//Multiplication table

for (int i = 1; i <= 10; i++) {
for (int j = 1; j <= 10; j++) {
cout << i << " * " << j << " = " << i + j << endl;
}
cout << endl;
}

system("pause>0");

I was watching this video as normal but The ending blew up my mind of how we can solve a huge problem from a small piece of code. I really like how you explained the concept.

[merveakbudak]

Such a teacher! I am really amazed by the way of explaining complicated subjects and making them so easy to understand. It is very nice to see an intelligent woman with the sense of humour. I would like to thank you so so much.

[hurleybanaag]

Thank you so much. now I know the flow of nested loops.

[tebellosephofane]

This really made me understand the nested for loop..You're Amazing Saldina😍😍

[yaserabd]

I love how relax you are , and how it was easy to explain it

[androvictrayo-dyeh]

Outstanding tutorial, thanks to you nested loop is easily understandable

[Flavzz]

Nice video, thank you for being very thorough. Much appreciated :)

[kelvins]

Using multiplication table to explain really help

[ayeshakhadim]

You are so cool. After your video, its seems like programming is easy, if we do it calmly. Thank you! Subscribed you!

[ព្រុំដែនញូ]

Thank you for you to complete my exercises

[davidalvarado]

It help me so much very different from html . thank you

[rudylucas]

Why are you using void main(), instead of int main()? I got an error on my compiler saying that it must return int. Can you explain? Thank you!

4 million is a big number to count to. it took someone 89 days to count to 1 million, 16 hours a day. it could easily take a year to count to 4 million. good stuff.

[manoharsagunthalla]

Will you please explain how to print the same tables in horizontal

[traianbadea]

Thank you for the tutorial is very helpful. I understand c++ due to your explication that is very good.

I try to mixt the last two lessons in one program. Thank you for your tutorial. All the best.

#include "pch.h"
#include <iostream>

using namespace std;

int main()
{
cout << " Exercise the multiplication table\n\n";
int i;
do {

cout << " Show the multiplication with ";

cin >> i;

cout << endl;

} while (i > 10);

for (int j = 1; j <= 10; j++)
{
cout << " " << i << " * " << " " << j << " = " << i * j<<endl;
}

cout << endl;




system("pause > 0");
}

Our teacher, we made j = 11,
How did j return again = 1?

*Kada koristimo nested loop racunar prati kod, u našem slučaju dolazi do 1. for loop (uzima vrijednost i=1), zatim ulazi u 2. for loop(uzima vrijednost j=1), pomnoži i ispiše. Nakon toga ne izlazi iz 2. for loop nego samo povećava vrijednost j do one vrijednosti koja je zadata tj. do 10 i tek nakon toga izlazi iz 2. for loop i ponovo se vraća na 1. for loop gdje uzima vrijednost i=2 i tako do kraja.. jesam dobro shvatio?

*Kojim tokom se stvari odvijaju ukoliko imamo npr. 4 for petlje (ugnijezdene) i nakon sto se 4. petlja zavrsi, da li racunar cita kod onda od 1. petlje pa sve ponovo ili prednost ima 3. petlja jer je ona najbliza posljednjoj tj. 4.

Nadam se da ste shvatili haha . LP

How can I develop the same program that asks the user to give me only even numbers?

[DavidLopez-vkgg]

Hello I am trying to create this one program that's like a store but I am having trouble in line 137 were I have put a while loop that pretty much a lows a customer to edit the amount of the item he wants but I cant seem to figure out hot to end the loop because after they don't want to edit anything anymore I thought I could just change the variable so the loop becomes false and it goes to the else statement but it doesn't work, if you have time for this I would appreciated and if you dont have time i understand.(I will put the whole block of code)
