是的,C++中的string匹配可以忽略大小寫(xiě)??梢允褂肅++標(biāo)準(zhǔn)庫(kù)中的algorithm函數(shù)tolower()將字符串轉(zhuǎn)換為小寫(xiě),然后再進(jìn)行匹配。例如:
#include <algorithm>
#include <cctype>
#include <iostream>
#include <string>
using namespace std;
int main() {
string str1 = "Hello World";
string str2 = "hello world";
transform(str1.begin(), str1.end(), str1.begin(), ::tolower); // 將str1轉(zhuǎn)換為小寫(xiě)
transform(str2.begin(), str2.end(), str2.begin(), ::tolower); // 將str2轉(zhuǎn)換為小寫(xiě)
if (str1 == str2) {
cout << "Strings match, ignoring case." << endl;
} else {
cout << "Strings do not match." << endl;
}
return 0;
}
輸出結(jié)果為:
Strings match, ignoring case.
