C++实现十进制转换为十六进制

#include <iostream> #include <string> using namespace std; string decimalToHexadecimal(int decimal) { string hexadecimalDigits = "0123456789ABCDEF"; string hexadecimal = ""; while (decimal > 0) { int remainder = decimal % 16; hexadecimal = hexadecimalDigits[remainder] + hexadecimal; decimal /= 16; } return hexadecimal; } int main() { int decimal; cout << "请输入十进制数："; cin >> decimal; string hexadecimal = decimalToHexadecimal(decimal); cout << "十六进制数为：" << hexadecimal << endl; cout<<"为了防止您直接运行exe文件而看不到结果，请手动关闭程序"<<endl; while(true) int i; return 0; }
