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
