运行时错误 - C 编程

Question

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main()
{
    int cases, num1, num2, var, *ptr2, count, i;
    scanf("%d", &cases);
    ptr2 = (int*)malloc(sizeof(int) * cases);
    memset(ptr2, 0, sizeof(int) * cases);
    if (ptr2) {
        for (count = 0; count < cases; count++) {
            scanf("%d", &num1);
            scanf("%d", &num2);
            for (i = 0; i < num1; i++) {
                scanf("%d", &var);
                ptr2[count] += var / num2;
            }
        }
        for (i = 0; i < cases; i++) {
            printf("%d\n", ptr2[i]);
        }
    }
    return 0;
}

问题描述如下https://a2oj.com/p?ID=17 它在 VS IDE 上运行得很好，但是由于某种原因，当我提交它时，他们的环境给我一个运行时错误。

Answer 1

切换'if (ptr2){'和'memset(ptr2,0...);'后解决了 – Andrew Naguib
