Does anyone know what Error while dumping state(probably corrupted stack) mean?

I just created this simple array and compiled it and ran it once it was finished I received this error message:

3 [main] a 6196 exception::handle: Error while dumping state (probably corrupted stack)
Segmentation fault (core dumped)

I am running Cygwin on Windows 7 64bit.

Code:

/* One Dimensional Array Source Code*\

#include <stdio.h>

main()
{
//Declare and Initialize Variables
int iArray[] = {0};
int iX = 0;
int iNum = 0;
int iCount = 0;

//Input Data Module
           
            printf("\n Enter a number:");
            printf("\n Enter 0 when done:");
            scanf("%d", &iNum);
                   
        while (iNum != 0)
        {
            iArray[iX] = iNum;
            iX ++;           
            printf("\n Enter a number:");
            printf("\n Enter 0 when done:");
            scanf("%d", &iNum);
            iCount++;
                       
        }//end while
       
           
//Display Data Module
         
        for  (iX= 0; iX <= (iCount -1); iX++)
        {
            printf("%d\n", iArray[iX] );
            iX = iX ++;
       
        }//end for
       
        return 0;
       
       
}//end program

How many elements does this array have?

It is defined by the user.

> It is defined by the user.
No, it's defined by the compiler to be one element long.

If you want a variable length array, you need to look into using malloc() and perhaps realloc()

> iX = iX ++;
Just remove this, you're already incrementing iX in the loop construct itself.

I'm sorry to ask but I am in an intro to programming class.
What is malloc() and realloc()?

Thanks so much..

Have you followed Salem's advice to "look into" them? If so, what have you learned?

There is plenty of information readily available about them, without having to ask people in a forum to explain them again.

I'm sorry I will look into them. Thanks for the advise. So the error message I was receiving is due the the array not being defined.

I really appreciate all your help.

Thanks.

No. The array is defined, and initialised with exactly one element. That is not a problem in itself.

However, your code later attempts to modify more than one element of that one-element array. That is a probable cause of the error message you received. Strictly speaking, anything is allowed to happen when you do that: an error message and program crash is just as correct as any other possible consequence.

One way to correct the problem is to increase the number of elements in the array. Another way is to only access the first element of that one-element array.

Please confirm with your tutor that you are supposed to deal with any length of input, or can assume say a maximum of 100 integers.

It greatly simplifies the solution (down to beginner level) if you can make this assumption.
