Find the size of the structure

Define a structure with members and thereby give the size of the allocated block of memory of the structure created.

Output: size of the structure is sizeof(int) + sizeof(char) = 104 bytes

Implementation:

#include <stdio.h> #include <stdlib.h> /* structure of student */ struct student { /* member variables */ int rollno; char name[100]; }; int main(void) { /* object 's' is created to access the allocated block of 104 bytes */ struct student s; /* collective size of the members of the structure student */ /* size of rollno (int type) & size of name (char array) */ printf("size of the structure is sizeof(int) + sizeof(char) = %d bytes ",sizeof(s)); return 0; }
