The parser() function takes a format string, a list of conversion functions, and a list of arguments. It identifies conversion specifiers in the format string, calling the appropriate function to print the corresponding argument. If a specifier is not recognized, it prints the character following the % symbol. Concepts: format strings, conversion specifiers, function calls, string manipulation, control flow.
The print_char() function takes a character as an argument and prints it to standard output. Concepts: character data type, standard output, function calls.
The print_string() function takes a string as an argument and prints it to standard output. Concepts: string data type, standard output, function calls.
The print_percent() function prints a percent symbol to standard output. Concepts: character data type, standard output, function calls.
The print_integer() function takes an integer as an argument and prints it to standard output. Concepts: integer data type, standard output, function calls.
The unsigned_integer() function takes an unsigned integer as an argument and prints it to standard output. Concepts: unsigned integer data type, standard output, function calls.
The print_binary() function takes an unsigned integer as an argument, converts it to binary, and prints it to standard output. Concepts: binary number system, unsigned integer data type, standard output, function calls.
The print_octal() function takes an unsigned integer as an argument, converts it to octal, and prints it to standard output. Concepts: octal number system, unsigned integer data type, standard output, function calls.
The print_hex() function takes an unsigned integer as an argument, converts it to hexadecimal in lowercase, and prints it to standard output. Concepts: hexadecimal number system, unsigned integer data type, standard output, function calls.
