Store and Display Information Using Structure in C++

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.

An example of a structure is as follows −

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

A program that stores and displays information using structure is given as follows.

Example

 Live Demo

#include <iostream>
using namespace std;
struct employee {
   int empID;
   char name[50];
   int salary;
   char department[50];
};
int main() {
   struct employee emp[3] = { { 1 , "Harry" , 20000 , "Finance" } , { 2 , "Sally" , 50000 , "HR" } ,    { 3 , "John" , 15000 , "Technical" } };
   cout<<"The employee information is given as follows:"<<endl;
   cout<<endl;
   for(int i=0; i<3;i++) {
      cout<<"Employee ID: "<<emp[i].empID<<endl;
      cout<<"Name: "<<emp[i].name<<endl;
      cout<<"Salary: "<<emp[i].salary<<endl;
      cout<<"Department: "<<emp[i].department<<endl;
      cout<<endl;
   }
   return 0;
}

Output

The employee information is given as follows:
Employee ID: 1
Name: Harry
Salary: 20000
Department: Finance

Employee ID: 2
Name: Sally
Salary: 50000
Department: HR

Employee ID: 3
Name: John
Salary: 15000
Department: Technical

In the above program, the structure is defined before the main() function. The structure contains the employee ID, name, salary and department of an employee. This is demonstrated in the following code snippet.

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

In the main() function, an object array of type struct employee is defined. This contains the employee ID, name, salary and department values. This is shown as follows.

struct employee emp[3] = { { 1 , "Harry" , 20000 , "Finance" } , { 2 , "Sally" , 50000 , "HR" } , { 3 , "John" , 15000 , "Technical" } };

The structure values are displayed using a for loop. This is shown in the following manner.

cout<<"The employee information is given as follows:"<<endl;
cout<<endl;
for(int i=0; i<3;i++) {
   cout<<"Employee ID: "<<emp[i].empID<<endl;
   cout<<"Name: "<<emp[i].name<<endl;
   cout<<"Salary: "<<emp[i].salary<<endl;
   cout<<"Department: "<<emp[i].department<<endl;
   cout<<endl;
}
