C/C++ :: Parsing Integers Values From Strings

So I have this assignment to read a file in, malloc some arrays, run it through a perceptron and to display the final weights. I have the majority of it already written but this is only my third program in C and I'm more familiar with Java and Python than C.

The problem I'm having is when I read in command line arguments, I can't seem to parse integer values from the strings in argv[i] by using atoi().

I've included the piece of code where I'm trying to 'parse.' I understand atoi convers ascii to integer, but I don't understand if it just gives you the ascii code or the number that it actually represents. I attempt to use atoi on lines 33-35

The input arguments in the command line are:

bob in.csv 100 5 10

int main(int args, char* argv[]){
int ** ra; // array of array of pointers
FILE *ifp; // file pointer
char cc; // char var for reading input from file
int i = 0; // counter
