void ft_print_comb(void) :
Initializes three integer variables, a, b, and c, each representing a digit.
Uses nested loops to generate combinations:
The outer loop (a) goes from 0 to 7.
The middle loop (b) starts from a + 1 to 8.
The inner loop (c) starts from b + 1 to 9.
Inside the innermost loop, it calls print_combination to print each combination of three digits.
The loops ensure that the combinations are printed in ascending order without repetition (e.g., 012, 013, 014...).
