Answer:

The correct answer for the given question is option(A) and option(C) .

Explanation:

To declared any variable of character we using following syntax

char variable=' value';

char  letter='w';

In option(A)  their is no single quotes between character w .So this is not a valid assignment.

In option(C) their is double quotes between character w,no single quotes  between character w .So this is not a valid assignment.

In option(B) their is single quotes between character w .So this is a valid assignment.

So option(A) and option(C) are are not valid assignment statement.

A) Valid if `w` is a `char` variable.

B) Valid (`'w'` is a `char` literal).

C) Invalid (`"w"` is a `String`, not a `char` literal).

In Java, a `char` variable can only be assigned a single character enclosed in single quotes (e.g., `'a'`, `'b'`, `'w'`). Therefore, valid assignment statements must adhere to this rule.

Let's analyze each option:

A) `letter = w;`

- This statement assumes `w` is a variable holding a `char` value. If `w` is not declared as a `char` and does not represent a valid character literal, this assignment will cause a compilation error.

B) `letter = 'w';`

- This is a valid assignment statement. `'w'` is a character literal representing the character 'w'. It matches the type `char`.

C) `letter = "w";`

- This statement uses double quotes, which in Java denote a `String` literal, not a `char` literal. Therefore, this assignment will cause a compilation error because you cannot directly assign a `String` to a `char` variable.

Conclusion:

The assignment statement that is not valid to assign the letter 'w' to a `char` variable in Java is **C) `letter = "w";`**.

Answer:

// here is code in c++.

#include <bits/stdc++.h>

using namespace std;

int main()

{

// initialize one Guinean_Francs

   double Guinean_Francs=9240.00;

   int u_s_d;

   double tot_Guinean_Francs;

   cout<<"enter the amount in U.S dollar:";

   // read the dollar

   cin>>u_s_d;

   // conver it into Guinean_Francs

   tot_Guinean_Francs=u_s_d*Guinean_Francs;

   print the output

   cout<<"total Guinean Francs is :"<<tot_Guinean_Francs<<endl;

return 0;

}

Explanation:

Declare and initialize a variable "Guinean_Francs" with 9240.00.Then read the  U S dollar from user and assign it to variable "u_s_d".Then multiply u_s_d  with Guinean_Francs and assign it to tot_Guinean_Francs. This will be the  total Guinean Francs.

Output:

enter the amount in U.S dollar:25                                                                                                                            

total Guinean Francs is :231000  

Final answer:

Option B (72 = amount;) is not a valid assignment statement because a constant value cannot be assigned to another value, whereas valid statements involve assigning values to variables.

Explanation:

The question is asking which of the given assignment statements in the context of a programming language is not valid. An assignment statement typically involves assigning a value to a variable.

The correct answer among the options provided is:

On the other hand, options A and C are valid assignment statements:

Answer:

#include <iostream>

using namespace std;

int main() {

int a=-156;//negative integer between -1 and -255.

a*=-1;//multiplying a to -1 so that it can become positive.

cout<<a;//printing a.

return 0;

}

Explanation:

The above written program is in C++ and in the program an integer a is defined with a negative value in the program it is -156.Then to convert it to positive integer we have to multiply a to -1 after that printing the value of a on the screen.

Answer:

3D ( in hexadecimal )

Explanation:

Converting the given hexadecimal numbers to decimal:

 67 (HEX) = 16*6 + 7 = 103 (Decimal)

 2A (HEX) = 2*16 + 10 = 42 (Decimal)

Subtracting the two numbers: 103 - 42 = 61 (Decimal)

Converting the result to Hexadecimal format:

61 = 16* 3 + 13

13 corresponds to D in hexadecimal.

So result in hex is 3D.

To summarize, the subtraction result for the two given hexadecimal numbers is 61 in decimal format or 3D in hexadecimal.

Answer:

function sum(number) {

      if (number == 1) {

             return 1;

      }

      return number + sum(number -1);

}

Explanation:

This is a recursive function, it means that is a function that calls itself for example: if you call the function with sum(5) the process is :

sum(5)

   |______ 5 + sum(4)

                           |_______ 4 + sum(3)

                                                       |______ 3 + sum(2)

                                                                                   |_____2 + sum(1)

                                                                                                        |_____ 1

Explanation:

The colon in square brackets is used to subsetting the list.

for example list1=[1,2,4,6,2,5]

print(list1[3:5])

This will print 6 ,2

Because it means the list from index 3 to 4 the last value is not inclusive.So if you write [:] it means the whole list and in the question we are assigning it to list2.So all the values from list1 will be copied to list2.

Answer:

False.

Explanation:

Index addressing is not for only traversing the arrays but to also access the element,manipulate them.Though indexing is also used in traversing but it is not solely for that.Indexing in an array starts from 0 to size-1.

for example:-

We have an array a of size 10.So to access the element at position 6.We have to write.

a[5];

Manipulating it

a[5]=6;

Answer:

Following are the program in Java

class abc // class abc

{

   public void area(int s) // function area

   {

       s=s*s;// calculate area

       System.out.println(" The area is:" +s + " ft"); // display the area

   }

    public void perimeter(int s) //function perimeter

    {

        s=4*s;//calculate perimeter.

       System.out.println(" The perimeter is:" +s + " ft"); //display the perimeter

    }

}

public class Main //class main

{

public static void main(String[] args) // main function

{

abc ob=new abc(); // creating instance of class abc

ob.area(7); // calling function area

ob.perimeter(7); // calling function perimeter

}

}

Output:

The area is: 49 ft

The perimeter is:28 ft

Explanation:

In  this program we create the class "abc" .We declared two function in the class "abc" i.e "area" and "perimeter" which is calculating the area and perimeter of a square and print them , from the main function we create a object of class "abc" i.e "ob" which called the function area and perimeter .

Answer:

//Here is the for loop in C.

for(n=10;n>0;n--)

{

   printf("count =%d \n",n);

}

Explanation:

Since C is a procedural programming language.Here if a loop that starts with n=10; It will run till n becomes 0. When n reaches to 0 then loop terminates otherwise it  print the count of n.

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

// main function

int main()

{  // variables

int n;

// for loop that runs 10 times

// when n==0 then loop terminates

for(n=10;n>0;n--)

{

   cout<<"count ="<<n<<endl;

}

return 0;

}

Output:

count =10

count =9

count =8

count =7

count =6

count =5

count =4

count =3

count =2

count =1

int main() // main method

{

 double rainfall[30]={45.5,78.9,67.78}; // array declaration and storing values

for(int i=0;i<3;++i) // iterating loop

{

    cout<<rainfall[i]<<endl; // printing the array elements

}

   return 0;

}

Output:

Final answer:

To find the location of any alphabetic character in a 2-character string, use two if statements to check both characters with Character.isLetter(), consider 0-based indexing while displaying a 1-based output.

Explanation:

The student is asked to write Java code that prints the location of any alphabetic character in a 2-character string called passCode. In Java, the method Character.isLetter() can be used to determine if a given character is a letter. To accomplish this task, two if statements can be used, one for each character in the string, and the indexes are 0-based. If an alphabetic character is found, the program outputs the location of the character using a 0-based index, but since users usually expect a 1-based index, we'll add one to the index before printing. Here is an example of how to write the code:

public class Main {
  public static void main(String[] args) {
      String passCode = "9a";
      if (Character.isLetter(passCode.charAt(0))) {
          System.out.println("Alphabetic at " + (0 + 1));
      }
      if (Character.isLetter(passCode.charAt(1))) {
          System.out.println("Alphabetic at " + (1 + 1));
      }
  }
}
For the string "9a", the output of this code would be "Alphabetic at 2" because 'a' is an alphabetic character at the second position (index 1).

Answer:

// here is code inn c++.

#include <bits/stdc++.h>

using namespace std;

// main function

int main()

{

// variable

   int t;

   double acc=32;

   cout<<"Enter the time in seconds:";

   // read the time in seconds

   cin>>t;

   // Calculate the distance=acceleration x time-squared divided by 2

   double dis=acc*(t*t)/2;

   // print the distance

   cout<<"distance is: "<<dis<<" feet."<<endl;

return 0;

}

Explanation:

Read the time in seconds from user and assign it to variable "t". declare and initialize variable "acc" with 32.Find the distance as "dis=acc*(t*t)/2". Print the distance.

Output:

Enter the time in seconds:10

distance is: 1600 feet.
