Convert a decimal integer to hex

Question

TJ · Accepted Answer

Assuming the conversion is from string to string (e.g. "10" => "A"), we can take several steps to convert:
1. Convert number string to int or uint (assume str is a decimal number string):
unsigned int num = 0;
for (int i = 0; i > 4;
    if (num < 10)
        hexStr = (num+'0') + hexStr;
    else
        hexStr = (num+'A') + hexStr;
}

1. Convert number string to int or uint (assume decStr is a decimal number string):
unsigned int num = 0;
for (int i = 0; i > 4;
    if (hex < 10)
        hexStr = (hex+'0') + hexStr;
    else
        hexStr = (hex - 10 +'A') + hexStr; // Need to subtract 10
