Exchange Value of two variables with the help of Third Variable In C

 Exchange Value of two variables with the help of Third Variable In C :

#include <stdio.h>

int main() {

    int a, b, c;

    // Ask user to enter two numbers

    printf("Enter Value of a & b: ");

    scanf("%d%d", &a,&b);

    // Add the two numbers

    c = a ;

    a = b ;

    b = c ;

    // Display the result

    printf("value after Swap of :

            a=%d and b=%d",a,b);

    return 0;

}

Explanation

Prompting the User: The program prints the message Enter Value of a & b: to ask the user to input two integer values.

Reading Input: The scanf function reads two integer values entered by the user and stores them in the variables a and b.

Swapping Values:

The value of a is assigned to the temporary variable c.

The value of b is assigned to a.

The value stored in c (which was originally the value of a) is assigned to b.

Displaying Result: The program prints the swapped values of a and b.

Example Run

If the user inputs 5 for a and 10 for b, the output will be as follows:

output :

Enter Value of a & b: 5 10

value after Swap of     :

              

a=10 and b=5       

Explanation:

• Initially, a = 5 and b = 10.
• After swapping, a = 10 and b = 5.
• The program then prints the swapped values.
