Thread: Enter an integer????

Helloooooo, I have one question! Is this any way to ask " Enter an integer" for n time?Instead of "Enter integers" and entering integer for n time? I tried printf but it didnot work!??

Code:

#include<stdio.h> 
void main() 
{ 
int n,m 


printf("Please enter a positive integer:"); 
scanf("%d",&n); 
printf("Enter integers:"); 
scanf("%d",&m);

Until you understand loop constructs and/or arrays - variable length arrays in particular - you will not be able to control the number of inputs read based on 'n'.

Your scanf("%d", &m); executes once and only once and stores one and only one integer in the variable m.

So, you mean it is not possible without arrays?

It depends on whether you want to store the data or just output it in some way as soon as it is entered.

With a loop, you could read the input, store it in a single variable, optionally modify it, and output it... repeat, overwriting the variable each time.
If you want all the data stored, you would need an array or at least enough int variables to handle the input. An array being the better choice.

ı am sorry I am a beginner I can not understand the loop part . You mean, if I wanna use loops, I have to identify a,b,and c instead of m if n=3 and I have to write printf and scanf for 3 times. Is it correct?

Any time you find yourself asking "How often do I want to do this?"... you're probably in a good position to use loops (for() while() or do while())

I know you're a beginner. I was basically telling you that until you get to at least loops in your learning you can't do what you are asking. Have patience.

And no, I meant quite the opposite. If you don't want to store the data, you can use a loop and have just one variable, m.

@CT and @ Tclausex, thanks for your answer I am trying to understand the logic of for but I didnt yet. For example in the exam there are many "for" that made up a triangle. I did it. But let me ask, we are always starting the loop inside,right? I mean if I am working on nested loops, first operation will be inside,right?

In nested loops the intial values are set as it tunnels in, then the inner most loop runs a full cycle for each count of the loop above it...

Thanks for the help.
