Programming Example
C Program to Store Information of Students Using Structure
This program stores the information (name, roll and marks) of 10 students using structures.
#include <stdio.h>
struct student
{
char name[50];
int roll;
float marks;
} s[10];
int main()
{
int i;
printf("Enter information of students:\n");
// storing information
for(i=0; i<10; ++i)
{
s[i].roll = i+1;
printf("\nFor roll number%d,\n",s[i].roll);
printf("Enter name: ");
scanf("%s",s[i].name);
printf("Enter marks: ");
scanf("%f",&s[i].marks);
printf("\n");
}
printf("Displaying Information:\n\n");
// displaying information
for(i=0; i<10; ++i)
{
printf("\nRoll number: %d\n",i+1);
printf("Name: ");
puts(s[i].name);
printf("Marks: %.1f",s[i].marks);
printf("\n");
}
return 0;
}
Enter information of students:
For roll number1,
Enter name: Tom
Enter marks: 98
For roll number2,
Enter name: Jerry
Enter marks: 89
.

.
Displaying Information:
Roll number: 1
Name: Tom
Marks: 98

This program stores the information (name, roll and marks) of 10 students using structures.
In this program, a structure, student is created.
This structure has three members: name (string), roll (integer) and marks (float).
Then, we created a structure array of size 10 to store information of 10 students.
Using for loop, the program takes the information of 10 students from the user and displays it on the screen.
First read the algorithm, then study the program code line by line. After that, compare the code with the output and finally go through the explanation. This approach helps learners understand both the logic and the implementation properly.
After understanding this example, try to rewrite the same program without looking at the code. Then change some values or logic and run it again. This helps improve confidence and keeps learners engaged on the page for longer.
