getchar() and putchar()

Syntax Getchar()

variable = getchar("characters");

example:

C = getchar("C");

C is the variable.

getchar() is the input function.

inner C is the character which was used in program

C = putchar("C");

C is the variable.

putchar() is the input function.

inner C is the character which was print on print screen.

clrscr ( );

c = getchar();

putchar(c);

printf ( "The input character is %c" , c );

getch ( );

}

Explanation:

• Header file as stdio.h and conio.h
• Main function that was heart of the c program
• Variable declaration, That "char c;" statement used for variable declaration. char keyword indicate the variable is based on character storing. 
• Clrscr() function was used to clear previous output on output screen.
• C variable was get the value from getchar() function. getchar() function is predefined. So i get single character from users. More than 1 character its cannot get. 
• Putchar() functions also predefined function it's display values which variable pass. 
• printf() also used to display statement of strings.
• getch() is the functions used to hold the output screen to use.
• end of file 

Its simple way of getting values from users by getchar() and putchar().
