避免缓冲区溢出,使用字符串操作函数(如strcpy_s和strncpy_s)而不是不安全的函数(如strcpy和strcat)。针对指针操作时进行安全边界检查,确保不会访问越界内存。2....并确保不超过input数组的大小 // 模拟处理输入的代码 char buffer[20]; strncpy(buffer, input, sizeof(buffer)); // 使用strncpy_s...处理后的字符串为:" << buffer << std::endl; return 0;}在这个示例代码中,我们通过使用std::cin.getline()函数来读取用户输入,并使用strncpy()函数(或strncpy_s
不要认为 strcpy_s 和 strncpy_s( 以及其他的字符串函数)(在空间不够的时候)会自动终止拷贝(truncate截断,不截断则意味着溢出).如果需要自动截断,请使用strncpy_s (
