Your way of teaching is so very easy to learn for a person who doesn't know to say

[vijisebastian]

The way you are teaching is easy to learn, explaining all the syntaxs meaning fully. Good Tutorials!

You are so much better than Bucky. Bucky has no rhyme or reason to the order in which he does his video list. Your video list is logically laid out, you explain every step, use vocabulary that programmers use often and define this vocabulary as you go. Hands down much better than Bucky, thanks a bunch.

i m a beginner and ur videos are helping me alot.But, at last if u give some question then it will be pretty helpful

[sgautamjain]

Fantastic, easy, lucid, comprehensive and simply explained. Enjoyed fully. Saw 22 videos from beginning today. Much better than any books available on the subject. Keep it up and cheers!

Sir your video tutorials are great . But it could be more better if you add some practice problems on every topics separately

Hi everyone, who notices that even if we do not return any values our code still works perfectly .I did my code and did not add return a+b and it worked .I ask chat gpt and it says the return value is only useful if we want to use it somewhere else like storing it to a variable or passing it to another function .I hope you understand and it helps someone else who is just starting

[javeriaahmed]

your videos are great and so easy to learn keep up the good work

[rajubejawada]

hello anil sir .i am quite gud in c programming.. i think the same concepts are applied here ..give me a suggesion how can i learn c++ now ..means from which video i started learing ..

[sthebassest]

This is a good format, keep it up, I hope to see a advanced CPP section.

why you use semicolun after display function
while after main function you didn't use any semicolun .why ?

[rutujavijaykumar]

Which 1 is more benefecial ?
using return statement in the function OR
giving cout command in the function
& also what difference does it causes in execution?

[likithreddy]

good explanatory skills anil bhai!! thank you for explaining c++ ...its very helpful

[carlosmiguel]

Question, so do you ALWAYS need to declare a variable that will display the return of the function even if you had already said return a+b? Or did you only do that because you wanted to say "the result is" ?

[arduinotutos]

great work !!! you r doing verry good continue

[rationalthinker]

One thing that bugs me is the following: Why would you call a function, such as the 'display' function before you build the body of the function with statements? It seem backwards to me and that you should fully build the function before calling it?

[aankit]

int add(int a, int b) {
cout << "Enter the first digit" << endl;
cin >> a;
cout << "Enter the second digit" << endl;
cin >> b;

if(a < 5 && b < 5) {
cout << "Please enter something more than 5" << endl;
} else {
return a+b;
}
}

int main() {
int result = add(4, 4);
cout << result;
retuen 0;
}

What arguments do we pass in the add function in Main. I am passing any numbers(4, 4) and it just runs fine, and it also checks my condition. But passing 4 and 4 doesnt make any sense .

[yosrimhamdi]

It is necessary to declare the function prototype?
what if I put the function body before I call it, so the function prototype will be unnecessary to use?

[nimminirmala]

sir why cant we type the name of the variable in the function prototyping itself
lkke void display( int a, int b );

[ironysteeth]

can you pass values from one function to another without having MAIN function mediating? Say in int ELFunction you get a return value of 50, can you use that return value in another fucntion without spoonfeeding it through main into the 2nd function?
