Question

C++

Read first a user's given name followed by the user's age from standard input. Then use an ofstream object named outdata (which you must declare) to write this information separated by a space into a file called outdata. Assume that this is the extent of the output that this program will do.

Declare any variables that you need.

Answer 1

Code Segment:

#include<bits/stdc++.h>
#include<fstream>
#include<iostream>
using namespace std;

int main()
{
// declaring variables to store data
string name;
int age;

// taking input from user
cin>>name>>age;

// declaring ofstream object
ofstream outdata;

// opening file named outdata.txt
outdata.open("outdata.txt");

// checking if the file is open
if(outdata.is_open())
{
// writing name followed by space and then age into the outdata.txt file
outdata<< name <<" "<<age;

// closing the file outdata.txt
outdata.close();
}

// if the file is not opened, display error opening in file
else
cout<<"error opening file";

}

Output:

Explanation:

As soon as you give the input Name and Age, a file named outdata.txt will be created in the same directory. And the given information will be written with a space between them in the outdata.txt file.
