How to Referencing a structure

Structure elements can be referenced by writing the structure variable before the structure element. The structure variable and the structure element are separated by a dot (.) which is called the dot operator. For example

st.name

st is a structure variable and name is an element in the structure

The program illustrates how to input and output elements in a structure. Details of employees namely code, name and salary are given as input in the form of a structure. The details of employees are also displayed in the same program.

#include<iostream.h>
void main() {
  char ch;
  struct employee {
  int code;
  char name[10];
  float salary;
} emp;
do {
  cout <<"Give the code of the employee: ";
  cin >> emp.code;
  cout<< "Give the name of employee: ";
  cin >> emp.name;
  cout<< "Give the salary of the employee: ";
  cin >> emp.salary;
  cout<<"\nCode: "<<emp.code<<'\n';
  cout<<"Name: "<<emp.name<<'\n';
  cout<<"Salary: "<<emp.salary<<'\n';
  cout<<"\nDo you want to enter more data? Type y or n. ";
  cin>>ch;
} while (ch= 'y');
}

Input and output:

Give the code of the employee: 10

Give the name of the employee: Sharma

Give the salary of the employee: 10000

Code: 10

Name: Sharma

Salary : 10000

Give the salary of the employee: 20000
