c - 程序没有使用 switch 语句，而是直接关闭

Question

以下代码：它为我的字符值/类型命中 scanf 语句的实例所有地狱都崩溃了程序立即关闭，没有错误代码，什么也没有。我觉得我正在失去它。我似乎无法弄清楚问题可能是什么，我没有任何随机中断语句或任何应该关闭代码的东西。请帮忙

#include <stdio.h>

    printf("Enter Charachter to draw with:\n");
    scanf_s("%c", &type);

        int count = 0;
        int count2 = 0;
        int firstcounter = 0;
