function to convert ascii to dec,hex, octal or binary?

[nbgoku]

is there a function in c++ or vc++ that converts a ascii to its dec,hex,octal, or binary value?

If your platform uses ASCII (which it probably does), then you can just cast the character to an int and display it in dec, hex, or octal format. Binary takes a little more work, but it should be pretty easy.

Example:

#include <iostream>
#include <iomanip>

int main()
{
    char c = 'A';
    std::cout << "   char: " << c << std::endl;
    std::cout << "decimal: " << static_cast<int>(c) << std::endl;
    std::cout << "  octal: 0" << std::oct << static_cast<int>(c) << std::endl;
    std::cout << "    hex: 0x" << std::hex << static_cast<int>(c) << std::endl;
}
