在这里,我们将看到如何在C ++中比较两个字符串。C ++具有字符串类。它compare()
在标准库中还具有比较字符串的功能。但是这里我们将使用条件运算符,例如==,!=,<,>,<=,> =。这些运算符逐个字符地检查字符串。让我们看一下代码以获得更好的主意。
#include<iostream> using namespace std; void compareStrings(string s1, string s2) { if (s1 != s2) cout << s1 << " is not equal to "<< s2 << endl; else if(s1 == s2) cout << "Strings are equal"; if (s1 > s2) cout << s1 << " is greater than "<< s2 << endl; else if(s1 < s2) cout << s2 << " is greater than "<< s1 << endl; } int main() { string s1("hello"); string s2("helLo"); compareStrings(s1, s2); }
输出结果
hello is not equal to helLo hello is greater than helLo
