Here we will learn about function with structure in C++ with the help of a Example store a student Details and subjects detail using structure.
In the Program function will be a member of a structure this is the also the main difference between C and C++ language.
In the program we store student Age, Student Name , Father Name in normal way while storing subject details we used the function.
Here is the Program,
store a student detail and subjects using structure with function in C++
#include<iostream>
#include<stdio>
using namespace std;
struct student
{
// data member declaration
int roll,age;
char st_name[20];
char f_name[20];
char sub [30];
// function member declaration
void get_subject();
void show_subject();
}x;
int main(void)
{
// storing personal information
cout<<"Enter Roll no: ";
cin>>x.roll;
cout<<"Enter Stu.age: ";
cin>>x.age;
cout<<"Enter Stu name: ";
gets(x.st_name);
cout<<"Enter Fa. name: ";
gets(x.f_name);
cout<<endl;
x.get_subject(); // calling function
// display record after screen clear
cout<<"\nShow Record";
cout<<"\nStudent Roll no: "<<x.roll;
cout<<"\nStudent age : "<<x.age;
cout<<"\nStudent Name : "<<x.st_name;
cout<<"\nStu. father name: "<<x.f_name<<endl;
x.show_subject();
return 0;
}
void student::get_subject()
{
cout<<"\nEnter Subject Detail:\n";
for(int i=0; i<5; i++)
{
cout<<"Enter "<<i+1<<" subject name: ";
cin>>x.sub[i]; // store subject name
}
}
void student::show_subject()
{
cout<<"Display Subject name: \n";
for(int i=0; i<5; i++)
{
cout<<i+1<<" subject name: "<<x.sub[i]<<endl; // display subject name
}
}OUTPUT
Enter Roll no: 101
Enter Stu.age: 23
Enter Stu name:Rohit sherma
Enter Fa. name:Rakesh sherma
Enter Subject Detail:
Enter 1 subject name: hindi
Enter 2 subject name: english
Enter 3 subject name: math
Enter 4 subject name: physics
Enter 5 subject name: chemistry
Show Record
Student Roll no: 101
Student age : 23
Student Name : Rohit sherma
Stu. father name: Rakesh sherma
Display Subject name:
1 subject name: hindi
2 subject name: english
3 subject name: math
4 subject name: physics
5 subject name: chemistryExplanation
In the program we used two function inside the structure get_subject() and show_subject()
after storing Personal detail function get_subject() will called and will be ask to the user for entered the subject detail, and in the same order Record will be display on the console.
