C++ 十进制转十六进制：使用 stringstream 实现

#include #include #include

using namespace std;

int main() { int num; cout << "Please enter a decimal number: "; cin >> num;

stringstream ss;
ss << hex << num;
string hexNum = ss.str();

cout << "The hexadecimal equivalent of " << num << " is: " << hexNum << endl;

return 0;

}
