在c ++中将字符串乘以int

#include<iostream>
#include<string>

std::string repeatString(const std::string& str, int n) {
    std::string result;
    for (int i = 0; i < n; ++i) {
        result += str;
    }
    return result;
}

int main() {
    std::string str = "abc";
    int n = 3;
    std::string repeatedStr = repeatString(str, n);
    std::cout<< repeatedStr<< std::endl;  // 输出 "abcabcabc"
    return 0;
}
