Different outptus from different compilers

[just_A_student]

A warm hello to all the contributors to this forum,

To be precise, two different compilers -
DevCpp ver 4.9.9.2 &
Tc by Borland ver 3.0
have given me two different outputs for the same program. TC excelled because it's output was what i intended it
to be, whereas DevCpp didn't produce the intended output.

The program -

/*
Assumptions - All alphabets are regarded irrespective of their cases. 'A' is considered same 
as 'a'. Numbers having multiple digits are looked as group of single digits. For example, 12 
is considered as digit 1 and digit 2. Absence of a histogram for any character should mean the 
absence of that character. All the other special characters except those mentioned above are 
not included.  
*/    

#include <stdio.h>    

#define SUCCESS 0  
#define ERROR  -1  
#define ALPHABETS 26      /* a - z, case - irrelevant */  
#define DIGITS	10	  /* 12 means digit 1 and digit 2 */	  
#define NEWLINE 2	  /* indices for the whitespaces */  
#define TAB	  1  
#define SPACE	  0  
#define WHITESPACES 3    

int main(void)  
{      
    /* Variable declaration and definitions */      
    int iExitCode = SUCCESS,
     	iInput = 0,
      	iAlphabets[ALPHABETS] = { 0 },
      	iNumbers[DIGITS] = { 0 },      	
        iWhiteSpaces[WHITESPACES] = { 0 },
      	/* iGap = 0, */
      	i = 0;    	

    /* Take input and fill the arrays with information */ 
    while((iInput = getchar()) != EOF)
    {
         if(iInput == ' ')
		iWhiteSpaces[SPACE] += 1;
         else if(iInput == '\t')
		iWhiteSpaces[TAB] += 1;
	else if(iInput == '\n')	
		iWhiteSpaces[NEWLINE] += 1;
	else if(iInput >= 'A' && iInput <= 'Z')
		iAlphabets[iInput - 'A'] += 1;
	else if(iInput >= 'a' && iInput <= 'z')
		iAlphabets[iInput - 'a'] += 1; 
	else if(iInput >= '0' && iInput <= '9')
		iNumbers[iInput - '0'] += 1;  
	else ;
     }

     for(i = 0 ; i < ALPHABETS ; i++)
	if(iAlphabets[i] != 0)
		printf(" %c = %d ", i + 'A' , iAlphabets[i]); 

     /* Exit code */ 
     printf("\n Press any key to exit...");      
     getch();
     return iExitCode;
}

The output -

By The DevCpp (Wrong one) :-
Starts by O, skipping A - N.... even if A has some entries.

By TC :-
Runs as intended, starts with A if A has any entries, and moves methodically

Friends, i don't know what is causing the DevCpp to output the kind that it is churning...

I am at my wit's end, and any help will be appreciated.

Thank u all in advance,

What input data are you using? It seems to work fine under gcc 2.95.3 in Linux (after removing the "press any key" message and the getch() call):

itsme@dreams:~/C$ ./count
iwauiovmnaOIFU29837849naonbhaiosfdjakls<EOF>
A = 5 B = 1 D = 1 F = 2 H = 1 I = 4 J = 1 K = 1 L = 1 M = 1 N = 3 O = 4 S = 2 U = 2 V = 1 W = 1 itsme@dreams:~/C$

I tried with multiple and different input sets, the outputs of all started out with R's frequency, if present.

I'm guessing that since you don't print any newlines that the output simply wraps over itself and hence "appears" to only start at certain letters.

Perhaps

printf(" %c = %d\n", i + 'A' , iAlphabets[i]);

[just_A_student]

No. That couldn't be the case as i used clrscr() in TC, but deleted the line for portability reasons.

And you're sure? What happens if you add a newline after every five outputs?
