Debug Error!解决方法

Debug Error!!!

C/C++ code

#include <iostream>#include <cstring>using namespace std;int main(){    char word1[] = "abcde";    char word2[5];    strncpy(word2, word1, 4);    word2[5] = '\0';    cout << word2;}

[解决办法]
没有完整安装开发包吧
我编译运行都正常
[root@localhost src]# g++ simple.cpp
simple.cpp:12:2: 警告：文件未以空白行结束
[root@localhost src]# ./a.out
abcd_trV
[解决办法]
C 字符串以 '\0' 结尾

数组下标从 0 开始

C/C++ code

word2[5] = '\0'; // 越界啦
