printf() and scanf() function in C printf() and scanf() functions are inbuilt library functions in C programming language 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 in C language. We have to include “ stdio.h ” file as shown in below to make use of these printf() and scanf() library functions in C program. #include <stdio.h> printf() function in C In C programming language, printf() function is used to print the “character, string, float, integer, octal and hexadecimal values” onto the output screen. Here’s a quick summary of the available printf format specifiers: %c character %d decimal (integer) number (base 10) %ld Long integer %e exponential floating-point number %f floating-point number %lf double number %i integer (base 10) %o octal number (base 8) %s a string of characters %u
