You see, I am a total beginner, thrown into a deep sea trying to swim...
Let me then explain what the program is supposed to do:
user enters all the integers to fill in an array num[3][4] (these dimensions only). Then I have to write a function to use in this program with 3 parameters: address of the array, no of rows and no of columns... The function calculates the sum of squares of all integers in the array (each int is squared and then they are all added up). That's what sumsquares is supposed to do.

When I initially tried to avoid giving all the dimensions, I keep getting either an error message (syntax error) or at least a warning. That's why I am so confused.
