Converting a string with a hexadecimal representation of a number to an actual numeric value

Question

I have a string like this:

\"00c4\"

And I need to convert it to the numeric value that would be expressed by the literal:

0         


        

Answer 1

#include 

int main()
{
        const char *str = "0x00c4";
        int i = 0;
        sscanf(str, "%x", &i);
        printf("%d = 0x%x\n", i, i);
        return 0;
}
