Prototype

int _printf(const char *format, ...);

Usage

• Prints a string to the standard output, according to a given format
• All files were created and compiled on Ubuntu 14.04.4 LTS using GCC 4.8.4 with the command gcc -Wall -Werror -Wextra -pedantic *.c
• Returns the number of characters in the output string on success, -1 otherwise
• Call it this way: _printf("format string", arguments...) where format string can contain conversion specifiers and flags, along with regular characters

Examples

• _printf("Hello, main\n") prints "Hello, Main", followed by a new line
• _printf("%s", "Hello") prints "Hello"
• _printf("This is a number: %d", 98) prints "This is a number: 98"
