- What are variadic functions
- How to use va_start, va_arg and va_end macros
- Why and how to use the const type qualifier
- 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
Mode: mandatory
File: 0-sum_them_all.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
Mode: mandatory
File: 1-print_numbers.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
Mode: mandatory
File: 2-print_strings.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
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
2 while loops
2 if
You can declare a maximum of 9 variables
You are allowed to use printf
Print a new line at the end of your function
Mode: mandatory
