Convert decimal VALUE(not string) to hexadecimal in C++

Question

I have a decimal value stored in DWORD, and I want to convert it in simple way to hex to send it as argument to another function.

Is there any efficient function to do it or I have to write it myself?

I don't need to print it - I need the hex value in DWORD variable.

"I don't need to print it - I need the hex value in DWORD variable" is an idiotic requirement. The proposed duplicate makes it a string. — Jongware, Feb 21 '16 at 10:50

Try something like this:

int numToConvert = 15;
std::cout << std::hex << numToConvert << endl;

This should give you hex of 15.
