Write code to define a function as follows: 1. function is named foo 2. foo takes a pointer to a character and returns an integer named x. 3. foo uses the pointer to check what it's pointing to, if it is a character terminator, the functions returns an integer named x. 4. If not, foo counts by 1 if a call to an assumed function named, check1 returns 1. check1 requires one character argument and returns 0 or 1. You do not need to write the definition of check1; assume it's already defined. 5. make sure to advance the pointer to the next character unless the terminator is found. C PROGRAM with prinf and scanf
