In this tutorial we are going to learn console input output int C++ with example in very easy way.
Input through keyboard and output on the monitor/ screen is known as console input output.
To perform input /output operations , there are various functions.
console input / output can be divided into two categories.
- Unformatted input / output functions
- Formatted input / output functions
Unformatted input / output functions
It is mainly used for characters. No any control string is used.
Unformatted input functions
1. getch()
It takes entry of a single character. Entered key doesn’t display on the screen . It has defined in #include<conio.h> header file.
2. getche()
It takes a single character and very similar to getch( ). Entered character prints on the screen . It has defined in #include<conio.h> header file.
3. getchar()
It is used to take entry of single character form keyboard. It has defined in #include<stdio.h> header file.
4. gets()
It is used to take entry of a string(more than one words at a time) from the keyboard. It has defined in #include<stdio.h> header file.
Unformatted output functions
1. putch( )
It displays the character on the screen. It has defined in #include<conio.h> header file.
2. putchar( )
It displays the character on the screen. It has defined in #include<stdio..h> header file.
3.puts( )
It is used to display string on the monitor. It has defined in #include<stdio.h> header file.
