7. Write a program to display the output as follows: Lets learn together C++ program
It is not so difficult
I

Output

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

.

.

.

Explanation:

e user and displays it on the screen.

Example: Store Information in Structure and Display it

#include <iostream>

using namespace std;

struct student

{

char name[50];

int roll;

float marks;

} s[10];

int main()

{

cout << "Enter information of students: " << endl;

// storing information

for(int i = 0; i < 10; ++i)

{

s[i].roll = i+1;

cout << "For roll number" << s[i].roll << "," << endl;

cout << "Enter name: ";

cin >> s[i].name;

cout << "Enter marks: ";

cin >> s[i].marks;

cout << endl;

}

cout << "Displaying Information: " << endl;

// Displaying information

for(int i = 0; i < 10; ++i)

{

cout << "\nRoll number: " << i+1 << endl;

cout << "Name: " << s[i].name << endl;

cout << "Marks: " << s[i].marks << endl;

}

return 0;

}

#include <iostream>  

using namespace std;

int main()

{

   cout<<"Lets learn together C++ program" << endl;

   cout<<"It is not so difficult" << endl;

   cout<<"I" << endl;

   return 0;

}

answer; insolated i/o uses separate memory space,and on the other hand memory mapped i/o uses memory from the main
