Circular Array Rotation

    Nice one!
    Here is my code in C. 

    #include <stdio.h>
#include <stdlib.h>


int main(){
    int n,k,q;
    scanf("%d %d %d",&n,&k,&q);
    int a[100000],m,i = 0;
    
    while(i < n)
        scanf("%d",&a[(i++ + k) % n]); 
    
    while(q--){
        scanf("%d",&m);
        printf("%d\n",a[m]);
    }
    return 0;
}

    Position resulting because of rotation is computed first using ((i++ + k) % n).Then the array elements are stored in these positions in the read ing stage itself using scanf() . Suggestions are welcome!
