打印输出在c++中居中对齐的解决方案

#include <iostream>
#include <iomanip>
#include <string>

std::string centerAlign(const std::string& text, int width) {
    if (text.length() >= width) return text;
    int totalPadding = width - text.length();
    int leftPadding = totalPadding / 2;
    int rightPadding = totalPadding - leftPadding;
    return std::string(leftPadding, ' ') + text + std::string(rightPadding, ' ');
}

int main() {
    std::string text = "Hello, World!";
    int width = 20;
    std::cout << centerAlign(text, width) << std::endl;
    return 0;
}

#include <iostream>
#include <iomanip>
#include <string>

int main() {
    std::string text = "Hello, World!";
    int width = 20;
    std::cout << std::left << std::setw(width) << text << std::endl;
    return 0;
}

std::string safeCenterAlign(const std::string& text, int width) {
    if (text.length() >= width) return text.substr(0, width);
    // 其余代码与centerAlign函数相同
}
