A program to swap two single dimensional arrays

C Programming Language 056

The following code shows how to write a program to swap two single dimensional arrays (Interchange their elements).

Program

#include <stdio.h>

void main()
{
    int a[5], b[5], temp, i, m, n;

    printf("Enter the sizes of a,b: ");
    scanf("%d %d", &m, &n);

    printf("a: ");
    for (i = 0; i < m; i++)
    {
        scanf("%d", &a[i]);
    }

    printf("b: ");
    for (i = 0; i < n; i++)
    {
        scanf("%d", &b[i]);
    }

    for (i = 0; i < m + n; i++)
    {
        temp = a[i];
        a[i] = b[i];
        b[i] = temp;
    }

    printf("\na: ");
    for (i = 0; i < n; i++)
    {
        printf("%d ", a[i]);
    }

    printf("\nb: ");
    for (i = 0; i < m; i++)
    {
        printf("%d ", b[i]);
    }

    printf("\n");
}

Result

Enter the sizes of a,b: 2 1
a: 3 7
b: 1

a: 1
b: 3 7
