Code:I'm trying to set up a matrix where user inputs first line...I can't see why this doesn't work. Can anybody tell me? #include<stdio.h> int usernotes(int P[][12], int); //is this not the defined function?? int main(){ int i,j,temp; int P[12][12]; //Initialize array to -1 rather than 0 for(i=0;i<12;i++) P[0][i] = -1; printf("Please enter 12 notes hitting enter after each one.\n"); for(i=0;i<12;i++) P[0][i] = usernotes(P,i); }
