Array within Structure

As we know, the structure is a collection of the different data types. Like normal data types, It can also store an array as well. In arrays within the structure, the member of the structure is an array.

The syntax for array within the structure:

struct struct-name
{
datatype var1; // normal variable
datatype array [size]; // array variable
- - - - - - - - - -
- - - - - - - - - -
datatype varN;
};
struct struct-name obj;

Example program for array within structure:

#include<stdio.h>
#include<string.h>
struct Student
{
int Roll;
char Name[10];
int Marks[3]; //array of marks
int Total;
float Avg;
};
void main()
{
int i;
struct Student S;
printf("\n\nEnter Student Roll : ");
scanf("%d",&S.Roll);
printf("\n\nEnter Student Name : ");
scanf("%s",&S.Name);
S.Total = 0;
for(i=0;i<3;i++)
{
printf("\n\nEnter Marks %d : ",i+1);
scanf("%d",&S.Marks[i]);
S.Total = S.Total + S.Marks[i];
}
S.Avg = S.Total / 3;
printf("\nRoll : %d",S.Roll);
printf("\nName : %s",S.Name);
printf("\nTotal : %d",S.Total);
printf("\nAverage : %f",S.Avg);
}

Output:

The memory allocated for structure variable s is 24 bytes(2-roll,10-name,6-marks,2-total,4- avg).
