Re: Convert string hex to int?
How would you do it manually?
Take the digit characters one at a time from the left and get their hex value and use those hex values to build the int value.
First problem is converting a digit character to a hex value. '0' is 0, 'a' is 10
Once you have the hex value then think about how to build the final value given a string of hex values left to right.
Think about how its done with a decimal number. Given "123" you'd get the 1 first and then multiply that by 10 and add the 2 and then multiply that by 10 and add the 3 giving 123.
If you don't understand my answer, don't ignore it, ask a question.
