Ahaaan I wasn't asking the basic type thing to just get started

It depends on what you mean by "learn", it depends what background you have, it depends how much time and effort you will dedicate to it
E.g. if you want to know the language to get a junior position, was using some other programming languages before and will spend a couple of hours every day to learn the language and practice then I would say from 6 months to 1.5 years you can reach this target.

https://gist.github.com/mgood7123/bed1a3f95be78829db534c38620df519 ok now that i have the appropriate info to determine if a region should be removed or kept, how would i go about removing any regions that are the same size or smaller than the upper most region with respect to if a region is transparent or opaque ?
or rather, how do i implement occlusion culling?

#Doubt Where and why floor() is used ?

#Doubt Where and why floor() is used ?
It is function that most people use in optimisation or while solving relations/functions based problems
Dr
It returns a value rounded to the lowest or greatest integer based on which function you’ve called - ceil or floor

Why we can't reassign static variable Globally?
Dr
Why we can't reassign static variable Globally?
Static variable in most cases or generally is a constant
Dr
A static variable’s function is to ensure that it can’t be used outside of its scope

static int num ;
num = 10 ; <-- why i can't do this ??
int main () { return 0;}
static int num ;
int main () { num =10; <-- why it is fine??
return 0;}

Variable celsius should be assgined a value.

Whts c in v(f) = a(f) + b(f) loop

sorry,have a mistakes

hi guys i have a question.
char s1[3] = "hi";
s1 = "test";
in the above example i can't do this because s1 is a static array ok?
but look below example
char s1[3] = "hi";
strcpy(s1,"test");
now no error and now s1 = "test"
how is this possible?
tnx
Ravi
Nope...c should be maximum of e1 and e2
Ravi
Also, array contains garbage values, first fill them with zeros, using memset (google it) and then start scanf

Can anyone help me please ihave a question in c language
Ask the question and people will think about it

Ask the question and people will think about it
Hmmm we have uses a fonction that have to show what the variables contained in the tableau
Fetheddine
// Prototype de la fonction d'affichage
void affiche(int *tableau, int tailleTableau);
int main(int argc, char *argv[])
{
int tableau[4] = {10, 15, 3};
// On affiche le contenu du tableau
affiche(tableau, 4);
return 0;
}
void affiche(int *tableau, int tailleTableau)
{
int i;
for (i = 0 ; i < tailleTableau ; i++)
{
printf("%d\n", tableau[i]);
}
}
Fetheddine
Why in the fonction we used a pointer.
Fetheddine
La fonction n'est pas différente de celles que l'on a étudiées dans le chapitre sur les pointeurs. Elle prend en paramètre un pointeur surint(notre tableau), 
Fetheddine
And how does it pointed to the tableau!

for (i = 0 ; i < tailleTableau ; i++)
{
printf("%d\n", tableau[i]);
}
}
did you write that code or is just an example that was given to you?
Fetheddine
He said our fonctipns are similar to the other fonctions the weve studied about pointeurs
The pointeur in fonction void is pointed to tableau in main fonction
Fetheddine
So myquestion is how the pointeur is pointed to tableau in main fonction
