C++ Program to Store Information of a Student in a Structure

A structure is a collection of items of different data types. It is very useful in creating complex data structures with different data type records. A structure is defined with the struct keyword.

Syntax

Here is the following syntax of structure.

struct employee {
 int empID;
 char name[50];
 float salary;
};

Example

A program that stores student information in a structure is given as follows.

#include <iostream>
using namespace std;
struct student {
 int rollNo;
 char name[50];
 float marks;
 char grade;
};
int main() {
 struct student s = { 12 , "Harry" , 90 , 'A' };
 cout<<"The student information is given as follows:"<<endl;
 cout<<endl;
 cout<<"Roll Number: "<<s.rollNo<<endl;
 cout<<"Name: "<<s.name<<endl;
 cout<<"Marks: "<<s.marks<<endl;
 cout<<"Grade: "<<s.grade<<endl;
 return 0;
}

Output

The student information is given as follows:
Roll Number: 12
Name: Harry
Marks: 90
Grade: A

Explanation

In the above program, the structure is defined before the main() function. The structure contains the roll number, name, marks and grade of a student. This is demonstrated in the following code snippet.

struct student {
 int rollNo;
 char name[50];
 float marks;
 char grade;
};

In the main() function, an object of type struct student is defined. This contains the roll number, name, marks, and grade values. This is shown as follows.

struct student s = { 12 , "Harry" , 90 , 'A' };

The structure values are displayed in the following manner.

cout<<"The student information is given as follows:"<<endl;
cout<<endl;
cout<<"Roll Number: "<<s.rollNo<<endl;
cout<<"Name: "<<s.name<<endl;
cout<<"Marks: "<<s.marks<<endl;
cout<<"Grade: "<<s.grade<<endl;
