Get integer value from character array

I have character arrays of 3 ascii characters representing range values from a sonar. I need to do some calculation on these values now. How can I convert the ascii char array to a valid integer ...

char* Sonar_Height
The above code declares an array of character pointers. I think you probably want an array of characters instead:
char Sonar_Height
Also, the atio function expects a NULL terminated string. You could increase the character array to length 4 and set the last character to NULL.
