C Programming

Question

#include<stdio.h>
typedef int ARRAY[10][10];
int main() {
   ARRAY arr[2];
   printf("Size is %d",sizeof(arr));
}

 

The program on running produces output Size is $800$

I know typedef is used for providing alternate names to existing datatypes. Can someone explain what's happening? Or correct me

Comments

a matrix of size 10x10=100 cells of integer type.

now each cell can store 2 integers .

total = 100x 2=200 cells...or 800 bytes(integer=4B)

Answer 1

typedef int ARRAY[10][10]

and ARRAY arr[2]

so  ARRAY replaced with arr[2] and becomes

int arr[2][10][10]

so sizeof(arr)=2*10*10*sizeof(int)=800
