7 – Best C program to reverse an array

#include <stdio.h>

int main ()
{
    int i,j,temp,nums[]={1,2,3,4,5,6,7,8,9};
    int l=sizeof(nums)/sizeof(int);

    printf("nOriginal array");
    for(i=0;i<l;i++)
    {
        printf("n nums[%d] = %d",i,nums[i]);
    }

    for(i=0;i<l/2;i++)
    {
         j = l-(i+1);
        temp=nums[j];
        nums[j]=nums[i];
        nums[i]=temp;
    }

    printf("nnArray in reverse order");
    for(i=0;i<l;i++)
    {
        printf("n nums[%d] = %d",i,nums[i]);
    }

    return 0;
