Try this code:

#include <stdio.h>

void rotleft(int arr[],int size,int d)
{
int temp;
size--;
while (d<size)
{
temp = arr[d];
arr[d] = arr[size];
arr[size] = temp;

size--;
d++;
}
}

int main() {

int a[50]={1,2,3,4,5};
int i,n,r;
printf("Ente4 size og array\n");
n=5;
r=2;
rotleft(a,n,r);
for(i=0;i<n;i++)
printf("\t%d",a[i]);
return 0;
}
