Write a complete C program that obtains two integers from the user, saves them in the memory, and calls the function void swap (int * a, int * b) to swap the content of the two integers. The main function of your program should display the two integers before and after swapping.

C program for swapping numbers

#include

void swap (int * num1, int * num2) / *Defining function for swapping the numbers*/

{

int temp; / *using third variable to store data of numbers*/

temp = * num1;

*num1 = * num2;

*num2 = temp;

}

int main () / /driver function

{

int a, b;

printf ("Enter the numbers for swapping/n"); //taking input

scanf ("%d %d",&a,&b);

printf ("The numbers before swapping is a = %d and b=%d / n", a, b);

swap (&a, &b); //calling function for swaping

printf ("The numbers after swapping is a=%d and b=%d", a, b);

return 0;

}

Output

Enter the numbers for swapping 3,4

The numbers before swapping is a = 3 and b=4

The numbers after swapping is a=4 and b=3
