In this simple tutorial, we will learn to get input from the user in C++. We will learn to take integer, character, string with spaces as an input. If you want to learn about the data types in C++ then go through the following tutorial.

Take Integer and Character as an Input from User

The program is simple, to take an input we use cin input stream present in C++. The program asks the user to enter an integer and displays that value on the screen. Then it also asks the user to enter a character and the value is again printed on the screen.

#include <iostream>
using namespace std;

int main()
{
  	// integer
   int val;
   cout << "Enter the Number: ";
   cin >> val;

   cout << "Integer Value " << val;

  	// Character
   char ch;
   cout << "\n\nEnter a Character: ";
   cin >> ch;
   cout << "Character value: " << ch;

   return 0;
}

Output:

Enter the Number: 25
Integer Value 25

Enter a Character: A
Character value: A

Get String Input with Spaces

We can get a string with spaces from the user with the use of gets() function or getline() function. Use them in the following way in the program.

gets(str);

getline(cin, str);

1. Take String input with Spaces using gets()

#include <iostream>
#include <stdio.h>
using namespace std;

int main()
{
   char str[200];

   cout << "Enter the String: ";
   gets(str);

   cout << "String entered: " << str;

   return 0;
}

Enter the String: This is simple2code.com
String entered: This is simple2code.com

2. Take String Input with Spaces using getline()

#include <iostream>
#include <string>
using namespace std;

int main()
{
   string str;

   cout << "Enter the String: ";
   getline(cin, str);

   cout << "String entered: " << str;

   return 0;
}

Enter the String: I am simple2code.com
String entered: I am simple2code.com
