C Programming Language 082

• Write a program to explain CALL BY VALUE

Program

#include <stdio.h>

void swap(int, int);
void main()
{
    int a = 10, b = 20;

    printf("Before swapping...\n");
    printf("a = %d\n", a);
    printf("b = %d\n", b);
    printf("\n");

    swap(a, b);
    printf("After swapping...\n");
    printf("a = %d\n", a);
    printf("b = %d\n", b);

    printf("\n");
}

void swap(int x, int y)
{
    int t;
    t = x;
    x = y;
    y = t;
}

Result

Before swapping...
a = 10
b = 20

After swapping...
a = 10
b = 20
