c - Magnitude of numbers -

problem : determine number of pos, neg , zeros entered user.

code in c:

#include <stdio.h>  void main() {     int pos, neg, 0 = 0 ;     char x[7] ;      int num = 0 ;     printf("\npress q quit anytime");     while( printf("\n") , gets(x)) {         num = atoi(x) ;         if( !strcmp(x , "q")) break ;         if( num > 0) pos++ ;         else if (num < 0) neg++ ;         else zero++ ;     }     printf("\npos nos: %d \tneg nos: %d \tzeros: %d", pos, neg, zero); } 

here, although neg , zeros being counted appropriately, positives not. shows positive numbers offset of 4196240 ie if there 4 positive numbers, show 4196244.

whats special 4196240? , why showing this?

you need initialize of counting variables. declaration initializes zero, leaving pos , neg uninitialized.

int pos = 0, neg = 0, 0 = 0 ; 

whats special 4196240 ? , why showing ?

it happens value when not initialized you, there's nothing special it, it's garbage value.
