Working with matrix

[dkn]

To show matrix M
void showV(int vv[])
{ int nn, i;
nn=sizeof(vv)/sizeof(int);
for(i=0; i<nn; i++) printf("%d, ", vv);
return;
}
void showM(int mm[][])
{ int i;
nn=sizeof(M)/sizeof(int);
for(i=0; i<nn; i++) showV(mm);
}

What's wrong ??
Thnx

Please tell us what's the problem you facing.

There's a few reasons this won't work. Or even compile. nn isn't declared in showM. In your print statements, you're not using your loop/index variables. Lastly, sizeof will not work on array arguments like that in C 'cause the compiler has NO idea how large they actually are. You'll most definitely have to pass in the number of rows and columns to the functions.
