In C programming language, printf() function is used to print the “character, string, float, integer, octal and hexadecimal values” onto the output screen.
The available convertion specifiers are:
%c: Prints a single character. %s: Prints a string of characters. %d: Prints integers. %i: Prints integers. %b: Prints the binary representation of an unsigned decimal. %u: Prints unsigned integers %p: Prints address of pointer %x: Prints the hexadecial representation of an unsigned decimal in lowercase letters %X:Prints the hexadecial representation of an unsigned decimal in uppercase letters %r: Prints a reversed string %R: Prints the Rot13 interpretation of a string Usage All the files are to be compiled on Ubuntu 14.04 LTS Compile your code with gcc -Wall -Werror -Wextra -pedantic .c Include the "main.h" header file on the functions using the _printf() Create a file (main.c) with below contend Example #include "main.h" #include <stdio.h> /*
- main - Entry point
- Return: Always 0 */
int main(void) { int a; int b; char *str;
str = "school";
a = _printf("%r\n", "hello"); /*expected: notrebloh*/
printf("--->%d\n", a); /*expected: 10*/
b = _printf("%r\n", str); /*expected: loohcs*/
printf("%d\n", b); /*expected: 7*/
b = _printf("%r\n", str); /*expected: loohcs*/
printf("%d\n", b); /*expected: 7*/
return (0);
