    g is initialized at 0 and so is i but i is then goes through the while loop and becomes how many positions in the array and g goes through the for loop and becomes the answer.

    There is no line in your posted code that initialized those two variables.
    Note: "," is not an assignment operator.

    oh yea the way to do that is i=j=0 and g=k=0.0 I forgot, thanks...i changed it but i still get this error:
    Code:
    /tmp/ccUFewuZ.o: In function `main':
    hw3.c:(.text+0xb7): undefined reference to `pow'
    collect2: ld returned 1 exit status

    Link in the math library; normally called just the letter "m".

    Now it actually compiles but it doesn't give me any output when i put in a hexadecimal number, why doesn't it work...i did the gcc -lm hw3.c -o hw3 and ./hw3 -lm, is there anything else wrong with the code?

    You print g with putchar, it's for characters so it will print a corresponding ascii value for g. g might be way larger than 127 since you raise 16 to the power of k in each iteration of your loop.
