How Can I Read and Handle Spaces as Input in C ?

Understanding Space Input in C

In C , the extraction operator (cin) by default skips whitespace characters when reading input from standard input. This is why spaces are ignored when trying to retrieve space characters directly using a character array as in the given code.

Handling Spaces with noskipws

To read spaces as well as other whitespace characters, you can use the noskipws manipulator:

cin >> noskipws >> a[i];

This manipulator instructs cin to read all characters, including whitespace. However, it may not be ideal in your case, as it will also read other whitespace characters such as tabs and newlines.

Using get() for Individual Characters

A more precise way to read space characters and other individual characters is to use the get() function:

cin.get(a, n);

This function reads n characters from the input stream and stores them in the array a. It stops reading either when it encounters a newline character (n) or after reading n-1 characters. Note that it's important to use an array of sufficient size (n) to accommodate all characters.

By using get(), you can check the individual characters and specifically look for the space character:

if (a[i] == ' ')
  // Do something when a space is encountered

This method allows you to handle spaces and other characters more selectively without the need to disable whitespace skipping globally with noskipws.
