Program to swap elements of two integer arrays using user define function in C

/*  
* C program to swap elements of two integer arrays
*/

#include <stdio.h>

// funtion to swap the elements of the two arrays
void swapElements(int *arr1 , int *arr2 , int n)
{
    int i=0,temp=0;
    
    for(i=0 ; i<n ; i++)
    {
        temp    = arr1[i];
        arr1[i] = arr2[i];
        arr2[i] = temp;

// main function
int main()
{
    int i=0;
    
    // define two 1d-arrays
    int array_1[6] = {0,1,2,3,4};
    int array_2[6] = {5,6,7,8,9};
    
    // Passing two arrays and the number of 
    // elements to Function
    swapElements(array_1,array_2,5);

	printf("\narray_2 [%d] : %d",i,array_2[i]);
    }

}

Output

The arrays after swap are..

arra_1 [0] : 5
arra_1 [1] : 6
arra_1 [2] : 7
arra_1 [3] : 8
arra_1 [4] : 9

array_2 [0] : 0
array_2 [1] : 1
array_2 [2] : 2
array_2 [3] : 3
array_2 [4] : 4
