Error in Program

[ashlee]

I tried declaring my structure as below in my C programming language:

struct test {
int x,y;
char exa[x][y];
}test;

I got error when I tried the above test structure. Why is it so? Can someone correct my program?

Question :

struct test {
int x,y;
char exa[x][y];
}test;
Hi,

It so happens that you are trying to declare an array of a variant size and so is the error. The size of the array must be a constant number. You can define a constant and then use that name as the size of the array.

#define MIN 10
#define MAX 50
struct test{
char exa[MIN][MAX];
}test;

int x=10;
int y=20;
struct test {
char exa[x][y];
}test;

I hope i have cleared your doubt.
