Hello
I have a question about set and get function in classes, if I have 3 classes have some common data member, can I write one set and get functions in global scope and link it as friend function?

Using friends doesn't sound as a good idea.
But what do you mean by common data member? If you h..

In C a lot. In C++, you can get by by learning to use smart pointers without having to worry about much of the complications about memory freeing and so on. But eventually when you advance into writing allocators and stuff, knowing about raw pointers does help a lot.

thanks a lot. Honestly, everything is possible to learn and the fact that I say it is hard is related to the amount of time I spend to learn cpp. But even though I read in the news or articles, I still do not understand the definition of pointers in the common sense. Because usually many people express things complicatedly
Strife
Actually, I have no idea why pointers should be used

You can use your smart phone and install online compiler or can use online compiler to compile your code.

not sure if that will support opengl

The same error
Must be something wrong with your code then. Unless you show your code, we can't help you.
This works fine for me.
#include <algorithm>
#include <vector>
#include <iostream>
int main(){
std::vector<double> v(5);
std::generate(v.begin(), v.end(), [&](){return 1.0;});
std::cout << v[2] <<std::endl;
}

Loops are used to repeat a block of code number of times until it meets the required condition
Consider gfg and do some basic codes on all three loops
For loop
While loop and
Do while

Hi everybody.
Below... Is a small code.
I d like to extract 2 numbers in a string but just the 2 first.
And also while input is incorrect
I ask again and again for input and i want to count the numbers in the string... If more than 2.
This line
c = sscanf(saisie,"%d %d",&a,&b);
Doesn't seems to do the job.
Any idea ? Tks
int main()
{
int a,b,c ;
char saisie[255];
do
{
printf("pls input a string with 2 numbers\n");
gets(saisie);
c = sscanf(saisie,"%d %d",&a,&b);
printf("c = %d\n", c);
} while (c!=2);
printf("you have input%d in first and %d in second\n",a,b);
}

Why are you do that, if you want to delete prevent first , now when he will be online it's not possible to him to see my suggestion
