Should I warn him?
Probably, you are the admin, not me (I rejected that responsibility long ago)

How we can print shapes using loops in c++?
Anyone can explain Concept/logic?

How we can print shapes using loops in c++?
Anyone can explain Concept/logic?
You are may be confused about nested loops.
Anonymous
I am confused to understand the logic/concept.
Roshan
Yes.
In case of a normal asterisk pattern like half pyramid. The first loop ends line and the inside loop prints it.
The loop inside will print 1 * if it's row 1, 2 * if it's row 2 and so on...

I am writing the code and if it will never print the given i'll share my code. Then Kindly help me.

You can i=size
For i to 1 decrease by one
i=j
For j to 1 decrease by one
Print star one time
Print new line

Can you tell me how can I change this one into which print half pyramid?
HaiNahi
No take the copy of variable from upper loop and then iterate it in the inside one
Roshan
Make star var go upto row.
I.e, star < row (in your case)

You should simply understand by intution

But I used star<row in condition in 2nd loop it works

I never asked the code, I asked the concept and logic.

But aren't you getting intution? You can even start with while loops if u don't know the syntax of for loop

I got admission in an institute but I can't understand my teacher. I asked this Question again and again and he tells me again and again but I can't understand. Because he tell me the code but I want to learn logic. If he tell me the logic and then I'll solve write the code for pyramid and other shapes like diamond etc.
Anonymous
I want to learn the logic not to read/write the code. If I learn the logic then i'll write the code using my mind.

You've used scanf() twice, remove the outer scanf() (outside while loop)
Roshan
Get it?

I tried it already, the code won't work if iill remove the outside or the inside

hey, trying to build matrix-rotate function but i don't understand how to do that. Even tried to look it up on YouTube but i found only one and didn't understood it (the rest were about rotate the matrix in 90 degrees, which i don't need)
Any help?

While loop is doing some nonsense. Try to run it after you remove while

After you check that the entered character is not Q, you again take input which discards the previous input and takes new one
Igor🇺🇦

I think you should use do while instead of while and remove the scanf outside of the loop.

It works when I remove the out side scanf on other compilers but not on VS

On other compilers, does the Q+enter feature works too?

It always prints "Wrong symbol" at least once tho, so it's not exactly the same

I simplified it until I get the desired results. Barney had incorrect code...

Your solution is fine, it works! (Just wanted to point out that it always prints "Wrong symbol" before exiting, that you could fix by adding a case 'Q': break;)
I would probably do it like this
while(1) {
scanf(" %d", &symbol);
if (symbol == 'Q') {
break;
}
switch (symbol) {
// ...

It's just the simplification. I also agree and work as you do...

Question, when you writing while(1)
It means while loop number 1?
Roshan

1 means true so while(true) is infinite loop
