C Program to Implement Call By Value using Functions

include

swap (int, int);
main()
{
int a, b;
printf(“\nEnter value of a & b: “);
scanf(“%d %d”, &a, &b);
printf(“\nBefore Swapping:\n”);
printf(“\na = %d\n\nb = %d\n”, a, b);
swap(a, b);
printf(“\nAfter Swapping:\n”);
printf(“\na = %d\n\nb = %d”, a, b);
getch();
}
swap (int a, int b)
{
int temp;
temp = a;
a = b;
b = temp;
}
OUTPUT:
Enter value of a & b: 10 20

Before Swapping:

a = 10

b = 20

After Swapping:

a = 10

b = 20
