将整数转换为 C++ 中的定长字符数组

#include <cstdio>

int main() {
    int num = 12345;
    char str[10];
    sprintf(str, "%d", num);
    printf("转换后的字符数组为：%s\n", str);
    return 0;
}

#include <iostream>
#include <sstream>

int main() {
    int num = 12345;
    std::stringstream ss;
    ss << num;
    std::string str = ss.str();
    char charArray[10];
    strncpy(charArray, str.c_str(), sizeof(charArray));
    std::cout << "转换后的字符数组为：" << charArray << std::endl;
    return 0;
}
