Input and output operations in C follow specific rules regarding whitespace characters. By default, the stream manipulators cin and cout ignore whitespace while reading or writing data. This can pose difficulties when attempting to capture space characters specifically.

In the provided code snippet:

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

the program ignores spaces during input. To resolve this, consider the following approaches:

Using noskipws Manipulator:

This manipulator disables the default whitespace skipping behavior:

cin >> noskipws >> a[i];
Copy after login

Using cin.get() Function:

This function reads characters from the input buffer, including spaces:

cin.get(a, n);
Copy after login

where n is the number of characters to read.

Note: cin.get() stops reading characters upon encountering a newline or reaching the specified limit. It appends a null character (
