To get the exact size of a type or a variable on a particular platform, you can use the
sizeof operator. The expressions sizeof(type) yields the storage size of the object or type in bytes.
Given below is an example to get the size of int type on any machine:

#include <stdio.h>
#include <limits.h>

int main()

{
printf("Storage size for int : %d \n", sizeof(int));

return 0;

}

When you compile and execute the above program, it produces the following result on
Linux:

Storage size for int : 4
