How to Read Spaces from Standard Input in C

When reading input using cin in C , spaces are typically ignored by default. This can be problematic if you intend to process characters including spaces. Here's how to address this issue:

One approach is to use the noskipws manipulator before cin. This manipulator explicitly instructs cin to read all characters, including whitespace.

int main() {
  char a[10];
  // Enable reading spaces
  cin >> noskipws;

  for (int i = 0; i < 10; i++) {
    cin >> a[i];

    if (a[i] == ' ') {
      cout << "It is a space!!!" << endl;
    }
  }

  return 0;
}

Alternatively, you can use the get function to read individual characters from the stream. get retrieves characters until it encounters a newline or the specified number of characters.

int main() {
  char a[10];

  // Read 10 characters into the array 'a'
  cin.get(a, 10);

  for (int i = 0; i < 10; i++) {
    if (a[i] == ' ') {
      cout << "It is a space!!!" << endl;
    }
  }

  return 0;
}

Both methods allow you to read spaces from the standard input stream and process them accordingly.
