有大佬能告诉我这段代码有什么问题吗？他一直输出乱码。

#include <stdio.h>

int main()
{
int n, c, l, r;

scanf("%d %d", &n, &c);

int a[10000], s[10000], sum[10000];

for (int i = 0; i < n; i++) {
    scanf("%d", &a[i]);
}

sum[0] = a[0];
for (int i = 1; i < n; i++) {
    sum[i] = sum[i - 1] + a[i];
}

for (int i = 0; i < c; i++) {
    scanf("%d %d", &l, &r);
    s[i] = sum[r] - sum[l - 1];
}

for (int i = 0; i < c; i++) {
    printf("%d\n", s[i]);
}

return 0;

}

你可能没有给每一个变量赋予初始值，这几个数组所有的变量都没有给赋值，有可能是编译器直接使用内存中的数据赋值了才导致乱码。

我认为你需要在 int a[10000], int b[10000], int c[10000] 的后面加上以下代码：

int arrLength = 10000;
for (int i = 0; i < arrLength; i++) a[i] = 0;
for (int i = 0; i < arrLength; i++) b[i] = 0;
for (int i = 0; i < arrLength; i++) c[i] = 0;

好像还是不行
