我的代码:
#include <iostream>
#include <cstring>
using namespace std;
bool t[10000];
int main()
{
int l, m, cnt = 0;
cin >> l >> m;
memset(t, 1, sizeof(t));
for (int i = 1; i <= m; ++i)
{
int a, b;
cin >> a >> b;
for (int i = a; i <= b; ++i)
{
t[i] = 0;
}
}
for (int i = 0; i <= l; ++i)
{
if (t[i]) cnt++;
}
cnt++;
cout << cnt;
}

@Howson_20120405 循环变量重复了
for (int i = 1; i <= m; ++i)
{
int a, b;
cin >> a >> b;
for (int i = a; i <= b; ++i)
{
t[i] = 0;
}
}
你这两个都是 i
