0-sum_them_all.c

Write a function that returns the sum of all its parameters.

• Prototype: int sum_them_all(const unsigned int n, ...);
• If n == 0, return 0

julien@ubuntu:~/0x0f. variadic functions$ cat 0-main.c
#include <stdio.h>
#include "variadic_functions.h"

/**
 * main - check the code
 *
 * Return: Always 0.
 */
int main(void)
{
    int sum;

    sum = sum_them_all(2, 98, 1024);
    printf("%d\n", sum);
    sum = sum_them_all(4, 98, 1024, 402, -1024);
    printf("%d\n", sum);    
    return (0);
}

1-print_numbers.c

Write a function that prints numbers, followed by a new line.

• Prototype: void print_numbers(const char *separator, const unsigned int n, ...);
• where separator is the string to be printed between numbers
• and n is the number of integers passed to the function
• You are allowed to use printf
• If separator is NULL, don’t print it
• Print a new line at the end of your function

julien@ubuntu:~/0x0f. variadic functions$ cat 1-main.c
#include "variadic_functions.h"

/**
 * main - check the code
 *
 * Return: Always 0.
 */
int main(void)
{
    print_numbers(", ", 4, 0, 98, -1024, 402);
    return (0);
}

julien@ubuntu:~/0x0f. variadic functions$ ./b
0, 98, -1024, 402

2-print_strings.c

Write a function that prints strings, followed by a new line.

• Prototype: void print_strings(const char *separator, const unsigned int n, ...);
• where separator is the string to be printed between the strings
• and n is the number of strings passed to the function
• You are allowed to use printf
• If separator is NULL, don’t print it
• If one of the string is NULL, print (nil) instead
• Print a new line at the end of your function

julien@ubuntu:~/0x0f. Variadic functions$ cat 2-main.c
#include "variadic_functions.h"

/**
 * main - check the code
 *
 * Return: Always 0.
 */
int main(void)
{
    print_strings(", ", 2, "Jay", "Django");
    return (0);
}
julien@ubuntu:~/0x0f. Variadic functions$ gcc -Wall -pedantic -Werror -Wextra -std=gnu89 2-main.c 2-print_strings.c -o c
julien@ubuntu:~/0x0f. Variadic functions$ ./c 
Jay, Django

3-print_all.c

Write a function that prints anything.

• Prototype: void print_all(const char * const format, ...);
• where format is a list of types of arguments passed to the function
• c: char
• i: integer
• f: float
• s: char * (if the string is NULL, print (nil) instead
• any other char should be ignored
• see example
• You are not allowed to use for, goto, ternary operator, else, do... while
• You can use a maximum of
• 2 while loops
• 2 if
• You can declare a maximum of 9 variables
• You are allowed to use printf
• Pint a new line at the end of your function

julien@ubuntu:~/0x0f. Variadic functions$ cat 3-main.c
#include "variadic_functions.h"

/**
 * main - check the code
 *
 * Return: Always 0.
 */
int main(void)
{
    print_all("ceis", 'B', 3, "stSchool");
    return (0);
}

julien@ubuntu:~/0x0f. Variadic functions$ ./d
