How to solve a C-segment failure with vectors?

Question

Look! I don’t know what’s going wrong. When I compile my code in the codeblock, it’s all right. However when I sent the code to the evaluation in the run codes, they returned that besides taking too long it is giving Segmentation Failure. Could someone help me?

#include <stdio.h>

int main(){

   int fib[60], N;

   scanf("%d", &N);

   int ent[N];
   fib[0] = 0;
   fib[1] = 1;

   for(int i=0; i < N; i++)
     scanf("%d", &ent[i]);

   for(int j=2; j < 60; j++)
    fib[j] = fib[j-1] + fib[j-2];


    for(int k=0; k < 60; k++)
    printf("Fib(%d) = %d\n", ent[k], fib[ent[k]]);

    return 0;
}

My intention with this code is to make that when the person type a number N, appear N spaces for it to fill that will be the position of the Fibonacci sequence so that it will be:

Entree:
3
2
3
6

Exit:
Fib(2) = 1
Fib(3) = 2
Fib(6) = 8

I hope you’ve made your point...
