Its not solution

really

it is

using goto is the worst idea one coudl possibly have
klimi
just solve the problem
klimi
and do find a way ariybd

if you want to get your solution: scanf doesn't input anything when you add a space so your condition doesn't work
But its working 😂, and when i dont add space than it is not working

In func1:
( ptr = first = &v1[0] ) != *ptr
In func2:
( ptr = *ptr ) != ( first = &v1[0] ) , but
*ptr != ( (void *) ptr = first = &v1[0] )
The question is, why in func2 "ptr" isnt equal to &v1[0]?
and apparently the ptr = *ptr, the pointer is equal to
your content.(?)

Sorry for reposting this. I think now is more clear what is my doubt.

Someone run this program
#include<stdio.h>
#include<conio.h>
main()
{
int a;
char b;
clrscr();
start:
printf("Enter any number \n");
scanf("%d",&a);
If(a%2==0)
{
printf("Even no \n");
}
else
{
printf("Odd no \n");
}
printf("Do u want to continue y/n \n");
scanf("%c",&b);
if(b=='n')
{
goto start;
}
getch();
return 0;
}

Can anyone tell what is the diffrence between
scanf(" %c",&a);
And
Scanf("%c",&a);
Using the space, whitespace characters are ignored and won't be read.

Than run that program which i have sent

Why? Are you facing any issues?
conio.h is not C standard btw
Anonymous
But why ??
olli
Please don't, this is not guaranteed to work (7.21.5.2.2.)
If stream points to an output stream or an update stream in which the most recent operation was not input, the fflush function causes any unwritten data for that stream to be delivered to the host environment to be written to the file; otherwise, the behavior is undefined.
olli
The correct way would be to discard the whitespace by using scanf(" %c", &b); and then if (b == 'y') {...}
olli
But why rely on UB if you can use a guaranteed way?
olli
That's alright, so I would advise to learn it "right" in the first place, getting rid of bad practices might be hard
olli
And there are infact reasons to use goto. The code shown above is however not a good example of it's usage.
Error, ressource handling and termination of nested loops might be possible use cases.
To repeat reading values you can and should be using regular loops
Anonymous
But if we use scanf(" %c",&b);
Than its wirking without using fflush

I have many other ways to soul problem but my question is why it is not working

What's not working?

scanf("%c",&b),

Than why its working scanf(" %c",&b); 😭

U should try to know bro

Sure 😁
olli
scanf("%c",&b),
After entering your number you confirm using "enter". This insert let's say a \n character to your input stream.
So you stream might look like 1234\n.
After reading the number, only the new line char is left.
Once you ask to enter y or n your input stream looks like \ny.
If you omit the space in scanf you are reading the next character in your stream, which is \n. y is still in your stream, you have not read it yet.
Using the space in scanf you discard all whitespace characters in the stream and read the next "meaningful" one, so y will be read. Your stream is empty
Edit: flushing the input stream can do whatever the implementers wanted it to do. If you are running a system, that clears the stream on flush, it will work too. In this case the flush will discard the new line element. However you are not guaranteed to see this behavior and flush might do nothing, in which case it would not work at all since your stream is not altered and you need to discard the character(s) on your own

The reason for goto are switch statements

Run it in turbo c and soul problem

In turbo c its not working

It only reads pointers. The sigir you give it tells it how to preprocess the values

How to design ui in c++
BinaryByter
then learn to google
BinaryByter
then, learn that Qt is shit
BinaryByter
then, learn that you should use C# for ui
BinaryByter
and C++ as a backend for that UI
