将ASCII十进制缓冲区转换为C++中的字符串或字符数组

#include <iostream>
#include <string>

int main() {
    int asciiBuffer[] = {65, 66, 67, 68, 69, 0}; // 示例ASCII十进制缓冲区
    int bufferSize = sizeof(asciiBuffer) / sizeof(asciiBuffer[0]);

    // 方法一：使用字符数组
    char charArray[bufferSize];
    for (int i = 0; i < bufferSize; i++) {
        charArray[i] = static_cast<char>(asciiBuffer[i]);
    }
    charArray[bufferSize - 1] = '\0'; // 添加结束符

    // 方法二：使用字符串
    std::string str;
    for (int i = 0; i < bufferSize; i++) {
        str += static_cast<char>(asciiBuffer[i]);
    }

    std::cout << "字符数组: " << charArray << std::endl;
    std::cout << "字符串: " << str << std::endl;

    return 0;
}
