C: Size of two dimensional array

Question

I need some help counting the rows and columns of a two dimensional array. It seems like I can\'t count columns?

#include 

int main() {

char res         


        

Answer 1

That's a problem of integer division!

int column = sizeof(result[0])/row;

should be

int column = 7 / 10;

and in integer division, 7/10==0.

What you want to do is divide the length of one row, eg. sizeof(result[0]) by the size of one element of that row, eg. sizeof(result[0][0]):

int column = sizeof(result[0])/sizeof(result[0][0]);
