字符数组和字符串用C ++比较 [英] Comparing character arrays and string literals in C++

问题描述

我有一个字符数组，我试图找出是否匹配一个字符串，例如：

I have a character array and I'm trying to figure out if it matches a string literal, for example:

char value[] = "yes";
if(value == "yes") {
   // code block
} else {
   // code block
}

这导致了以下错误：有明确的行为字符串结果进行比较。我也尝试过这样的：

This resulted in the following error: comparison with string literal results in unspecified behavior. I also tried something like:

char value[] = "yes";
if(strcmp(value, "yes")) {
   // code block
} else {
   // code block
}

这并没有产生任何编译器错误，但预期它不表现。

This didn't yield any compiler errors but it is not behaving as expected.

推荐答案

的 的std :: STRCMP 如果字符串相等返回0。

std::strcmp returns 0 if strings are equal.
