C Tutorial for Beginners In Telugu Scanf Part 5

printf() and scanf() functions are inbuilt library functions in C which are available in C library by default. These functions are declared and related macros are defined in “stdio.h” which is a header file.
We have to include “stdio.h” file as shown in below C program to make use of these printf() and scanf() library functions.

C printf() function:

printf() function is used to print the “character, string, float, integer, octal and hexadecimal values” onto the output screen.
We use printf() function with %d format specifier to display the value of an integer variable.
Similarly %c is used to display character, %f for float variable, %s for string variable, %lf for double and %x for hexadecimal variable.
To generate a newline,we use “n” in C printf() statement.

Note:

C language is case sensitive. For example, printf() and scanf() are different from Printf() and Scanf(). All characters in printf() and scanf() functions must be in lower case.
