Thread: array problem

Code:

#include<stdio.h>
#include<conio.h>
  void main(){
	int x[10],i,square=0;
	clrscr();
	for(i=0;i<10;i++)
	  square=x[i]*x[i];
	printf("square=%d",square);
	getch();
}

Now lets look at it closer ( btw u use code tags like this [ code ] to close it [ /code ] - of course without the spaces between [ and / and [ and c ///hope that makes sense)

First of all never use void main use
int main and return 0 at end of main

Do not use clrscr see FAQ why it is a bad thing to use, there are more portable ways.+ i dont see any need of using that function here.

Now look at this piece of code

Code:

#include<stdio.h>
#include<conio.h>
int main(){
 int x[10];
 int i;
 int square=0;
 for(i=0;i<10;i++){
  square=x[i]*x[i];
  printf("square=%d\n",square);
  }
  getch();
 return 0;
 }

when u compile everything is still oke but when u run it you should get pretty strange outputs...


HINT: i didnt define something, in other words there is something undefined in your code which causes all your poblems...

Try and see if you can solve it now....

Aaah forget ...

your are not defining int x[10];
at all...
x[0] can be 1245445 or whatever it feels like at the moment...

Do a board search on how to declare arrays,
at least that way you will have done something on this one...
