Answer 1

The biggest problem is that you did not assign any initial values ​​to the following variables : d, g, premier, dernier, even though you used them in functions.
I think you mean by premier the first and by dernier the last so, you have to add this two line befor using them :
premier = 0;
dernier = n-1;
i don't know what d, g need for, but you have to assign them initial values.
in line 104 remove return, and add return 0; at the end of code.

Answer 2

In lines 80 and 81. Make it lecture(t, x); and
affichage(t, x); n has no value there.

Answer 3

Why are t and n arguments for these functions? n doesn't have an value yet. x has a value, but you aren't using it.
lecture(t,n);//calling the function in order to enter the elements of the array
affichage(t,n);//printing them

Answer 4

Yes indeed.

Answer 11

i=g and j=d

Answer 12

yes i see that inside the function, but in main() function, g = ? And d = ?.

Answer 13

Why please is it necessary

Answer 14

You used d and g as tri_croissant_rapid function parameters,
tri_croissant_rappide(t,n,g,d); in line 91
but g and d have no value, how the function will use them?

Answer 15

What do you mean by d and g? what's their role in the code?

Answer 16

Gauche for g and droite for d
Quick sort method in ascending order
I can also use low and high

Usually، use 0 for the low value, and n-1 (array.size() -1) for the hight value.

Answer 18

In the main function ??
