为什么即使字符串相同，此代码也会将输出视为false？ [英] Why this code is giving output as false even when strings are same?

问题描述

我给了两个字符串相同的值，但它仍然说条件是假的。



我尝试了什么：

I have given two strings the same values but still it's saying the condition is false.

What I have tried:

char s[] = "hello", t[] = "hello";

	std::cout << "s: " << s << std::endl;
	std::cout << "t: " << t << std::endl;

	std::cout << (s == t ? "true" : "false") << std::endl;

推荐答案

您正在比较两个字符数组的地址，而不是它们的内容。切换到std :: string或使用strcmp，请参阅此处的讨论：



比较C ++中char数组的值 - Stack Overflow [ ^ ]

You're comparing the address of the two character arrays, not their contents. Either switch to std::string or use strcmp, see discussion here:

Comparing the values of char arrays in C++ - Stack Overflow[^]

这是因为字符串不是怎么样的比较。

in s == t ，你要比较两个字符串的地址，它们总是不同。

This is because is not how string are compared.
in s == t, you are comparing the addresses of both string, and they are always different.
