Earlier we discussed on the basic introduction and structure of C, preprocessor it's features, intermediate and executable codes. compilation and execution process of a C program. And keywords and identifiers, data types, variables and constants, scope of variables, operators and expressions in C. Type casting in #C. Introduction to input and output functions and reading a character in #C.

In this section we will discuss on writing a character using many inbuilt #C functions like printf, putchar(), puts, putche, putch etc.

Writing a character :-

We know that there are many inbuilt functions for reading a text or character in #C like scanf, getchar, getch etc.. Same as that there are many functions for also writing a character like printf, puts, putchar, putch, putche etc.

This take form as shown below :

putchar (variable_name);

Here putchar is an inbuilt function used for printing any char type variable_name as an output.

This can be better understand by taking an example of program :

Input :

#include
main()
{ char a;
printf("enter any character");
printf("\n");
a = getchar();
putchar(a);
}

Output :

enter any character
Y
Y
enter any character
H
H
