为什么使用后strdup(value)
(int)value
返回的输出与以前不同?如何获得相同的输出?
我的简短示例出错了,请使用长示例:这里是完整的测试代码:
#include <stdio.h>
#include <iostream>
int main()
{
//The First Part
char *c = "ARD-642564";
char *ca = "ARD-642564";
std::cout << c << std::endl;
std::cout << ca << std::endl;
//c and ca are equal
std::cout << (int)c << std::endl;
std::cout << (int)ca << std::endl;
//The Second Part
c = strdup("ARD-642564");
ca = strdup("ARD-642564");
std::cout << c << std::endl;
std::cout << ca << std::endl;
//c and ca are NOT equal Why?
std::cout << (int)c << std::endl;
std::cout << (int)ca << std::endl;
int x;
std::cin >> x;
}
