C++处理字符串时遇到Program received signal SIGSEGV, Segmentation fault.

Question

程序

#include <iostream>
#include <string>
using namespace std;
int main()
{
    string s;
    cin >> s;
    cout << s;
    return 0;
}

只要进行单步调试，codeblocks就会弹出提示框Program received signal SIGSEGV, Segmentation fault.
这是怎么回事？

Answer 1

你的代码没问题，估计是 CodeBlocks 的问题。
