cnt初始化一下就好了
```c
#include <stdio.h>
int main() {
int sum = 0, a[12] = { 0 }, i, cnt = 0;
for (i = 0; i < 12; i++) {
scanf("%d", &a[i]);
}
for (i = 0; i < 12; i++) {
a[i] = 300 - a[i];//求这个月剩余的钱
sum += a[i];//每个月钱的总和
if (sum >= 100) {
cnt += (sum / 100);
sum %= 100;
}
if (sum < 0) {
printf("%d", -(i + 1));
break;
}
}
if (sum >= 0) {
printf("%d", cnt * 120 + sum);
}
return 0;
}
```
