Assignment name : ft_itoa_base Expected files : ft_itoa_base.c Allowed functions: malloc
Write a function that converts an integer value to a null-terminated string using the specified base and stores the result in a char array that you must allocate.
The base is expressed as an integer, from 2 to 16. The characters comprising the base are the digits from 0 to 9, followed by uppercase letter from A to F.
For example, base 4 would be "0123" and base 16 "0123456789ABCDEF".
If base is 10 and value is negative, the resulting string is preceded with a minus sign (-). With any other base, value is always considered unsigned.
Your function must be declared as follows:
char *ft_itoa_base(int value, int base);
