I really fell on the floor laughing at 8:15, thanks for showing that mistakes happen even to the best programmers!

[christianmcdermott]

Thank you for the tutorials! These are making learning C++ a joy.

[MartinsLicis]

Love your tutorials! They’re helping me a lot! Also maybe I missed it.. why are you using void main() instead of int main()?

[hazal]

I paused the video after you explained the comment lines then wrote the code by myself. And IT WORKED. Thank you soooo much. This is the firs time I feel like I am learning something rather than copying the instructions from the examples

Hi! I'm a foreign learner and tried many many tutorials, but YOU ARE THE BEST. I love how you always start with a flow chart, explain every small thing and your videos are clearly understandable both visually and audibly. I have ADHD and you are the first instructor to get my attention all along. If you'd make tutorials for all programming languages, I'd learn them all. ❤

THAT SENSE OF SATISFICATION WHEN CODE GIVES APPROPIATE OUTPUT.

Finally, I have found a C++ teacher from whom I can learn without feeling like my mind is wandering or losing focus. Student from Taiwan.

[takwanamusariri]

For this tutorial i challenged myself to only use the comments that you provided at the beginning of this tutorial and my understanding of previous tutorials that you taught and wow i did it. You are an awesome teacher, i am grateful.

Subbed because this video saved me lol. I'm just starting programming and couldn't get into the Intro class so I got put straight into C++ and it's pretty overwhelming. I've tried doing tutors but they make me feel stupid talking to them so with videos like this it shows step by step but also even a very smart person like yourself can make mistakes. Thanks again and I'll be going through your videos on my spring break and practicing.

This is excellent content. Best of wishes to you, keep up the great work!!

8:56 gave me a good laugh😂 I really enjoy these tutorials :D

Why i am getting your bmi is inf after running program and inputting values please help

[jessemoore]

Took me a bit to get right, but I also added a couple features. 1) Enter height in feet and inches and it'll convert for you. 2) It will also tell you how much you need to gain or lose to be in the normal range. (And I know I can delete the brackets but they make the code easier for me to read)

#include <iostream>
using namespace std;


int main()
{
float heightFT;
float heightIN;
float weight;
cout << "Please enter you weight (LBS) then height in feet then inches :";
cin >> weight >> heightFT >> heightIN;
float truHeight = ((heightFT * 12) + heightIN);
float bmi = ((weight / (truHeight * truHeight)) * 703);
float w2liow = ((bmi - 25) * 9.1288);
float w2giuw = ((18.5 - bmi) * 9.3140);



if (bmi < 18.5)
{
cout << "You are underweight, you need to gain ~" << w2giuw;
}
else
{
if (bmi > 25)
{
cout << "Your are overweight, you need to lose ~" << w2liow;
}
else
{
cout << "Your weight is within normal range";
}
}


system("pause>0");
}

For the English system substitute this formula- Enter weight to the nearest pound and height in inches. BTW, you are a natural teacher and I'm saying this as a Master Degreed educator with 20 years of experience. Excellent videos.

[grsrigel]

I was happy and motivated to learn coding till i tried the program. I'm crying now. Are you happy Saldina?

Thanks for the video. :D

[jamichaelwright]

this may be a dumb question but i was just wondering why you used
void main()
instead of
int main()
????

i get a warning saying
"return type of main should be 'int' instead of 'void'"

[pharos]

I made a bmi calculator with pounds and inches

#include<iostream>;
using namespace std;


int main()
{
float weight, height, bmi;
cout << "Weight(p), height(in)";
cin >> weight >> height;
bmi = (weight * 703) / (height * height);


if (bmi < 18.5)
cout << "Underweight" << endl;
else if (bmi > 25)
cout << "Overweight" << endl;
else
cout << "Normal weight" << endl;
cout << "Your bmi is : " << bmi;




system("pause>0");
}

[rocketleague]

do you have anything about data structutes and their implementations

[talhasphotography]

I tried to make this . Can u plz tell me it is right or wrong.
