Thank you so much, I was overthinking how to do this so much. Can't believe how simple it really is

[chriscruz]

Thank you for making tutorial like this, I can't believe how these videos only have a few thousand views. Your cpp tutorials are making me pass my class easily.

During this lockdown in France, only these videos are helping me keep my sanity. Thanks Caleb.

thanks my man this is very informative!!! was just looking about how to make a vector template & passing it around to functions, I'll just keep looking! great channel, just subbed

[zsoulz]

hello, could you explain more about passing by value vs passing by reference? THANK YOU VERY MUCH

[mohammedaladaqf]

Big thank to u. Ur explanation is easy understood and simplifying

[abdelrhmanahmed]

good practice:
dont put data.size inside loop condition because each time it will goo and calculate the size and that not good optimization, instead crest variable int s= data.size(), and put s inside the loop condition

[jamshaidmushtaq]

Thank you for that. I was taught nothing about vectors, and suddenly I had to use them in an assignment at my university. I might just prevail because of watching two or three of your videos on vectors!

If we want to return a vector how should we do??

[AdamCJost]

Easy enough, but it should be important to note that the the new line escape character in modern programs should be replaced by endl. Also since vectors are not primitive data types and you are not changing the vector within the function wouldnt you suggest passing by const reference opposed to passing by value?

[PunmasterSTP]

Thanks for these wonderful videos; I think they're a great &!

[brocklesnarufcchamp]

Awesome stuff! Now how to return vectors from functions?

[damnnits]

I had to declare my variable before like this:
int sample;
std::vector<int> sample = {1, 2, 3};
print_vector(sample);
Or I got an error. I dunno why.

[dbaby]

Now if the print vector actually returns the modified vector back to the main function. Does the print vector copied vector free up the memory?

[kdtallllll]

Regarding using the i's in the for loop, do we always use i? Can we use any character? I'm just confused as to why it's i when there's no i anywhere else in the program, I think I might have to rewatch your for loop video again!

People outside the door, eh? Sometimes people are better left outside. Burn. xD

[DanmanJR]

I keep getting an error with the for(int i = 0; < data.size(); i++) in the <.
The error is rror: expected primary-expression before '<' token
6 | for(int i = 0; < data.size(); i++). Any help?

[alnajafyprogrammer]

hello i am from iraq, what is library that contains "vectors", ,

[ammgnero]

#include <iostream>
#include <ctime>
#include <cstdlib>
#include <vector>

using std::cout;
using std::cin;


void print(std::vector<int> one)
{

for (i = 0; i < one.size();i++)
{
cout << one[i] << "\t";

}
}

int main()
{
std::vector<int> two = { 1, 2, 3 };
print(one);



}

hey Caleb can you please tell me what's wrong with my code?

[anthonychadwick]

Why on Earth would you not explain how to return a value
