Read and Display the Contents of Input

Certification: Basic Level Accuracy: 85.71% Submissions: 14 Points: 10

Write a C++ program that reads and displays the contents from user input. The program should take input from the user and display the contents.

Example 1
     
  • Input: string = "Hello World"
    •  
  • Output: "Hello World"
    •  
  • Explanation: 
       
    • Step 1: Allocate memory for storing the input string.
      •  
    • Step 2: Read characters from the standard input stream using pointers.
      •  
    • Step 3: Store the characters in the allocated memory.
      •  
    • Step 4: Display the stored string to the standard output stream.

Example 2
     
  • Input: string = "C++ Programming"
    •  
  • Output: "C++ Programming"

Constraints
     
  • Input size ≤ 10^6 characters
    •  
  • Input contains printable ASCII characters
    •  
  • Time Complexity: O(n) where n is the number of characters in the input
    •  
  • Space Complexity: O(n) for storing the input

Solution Hints

    
  
  • Use string stream to handle input instead of file handling.
    • 
  
  • Read the input character by character or line by line.
    • 
  
  • Display the contents of the input.
    •

Steps to solve by this approach:

 Step 1: Define a function displayContents that takes a constant string reference as parameter.

 Step 2: Create an input string stream with the provided string.

 Step 3: Iterate through the stream character by character using get().

 Step 4: Print each character to the console.

 Step 5: In main, prompt the user to enter content.

 Step 6: Use getline to read the input into a string variable.

 Step 7: Call displayContents with the input string.
