cin.get(ch) function function

cin.get(ch) is in the C standard library Member function of the input stream object (cin) that reads a single character from standard input and stores it in the specified character variable ch.

How it works

When cin.get(ch) is called, it will:

• Read a character from standard input .
• Store the read characters in the character variable ch.
• Returns the ASCII code of the character read.

If the input stream has reached the end of the file, cin.get(ch) returns EOF (end of file flag).

<code class="c++">char ch;
cin.get(ch);</code>

The above code reads from the standard input Reads a character from and stores it in the ch variable.

Note

• The cin.get(ch) function cannot be used to read space characters.
• If there are space characters in the input stream, you need to use the cin.ignore() function to ignore them.
• cin.get(ch) function reads characters, not strings. To read a string, you need to use the cin.getline() function.
