Thread: Need help with the output plz

I remember someone else had a homework problem that they wanted us to solve. In search to find something to do I decided to attempt it. I have worked about 90% of it and would like help finishing it. I would post it back into the original thread but I dont want to do his/her homework and figure that he does not read the forums and just simply wanted an answer.
The person's homework was to have an output read
1
22
333
4444
55555

well check out my code then I will ask my question.

Code:

#include <stdlib.h>

main()
{
int i,x,x1,d;
for(i=0;i<=5;++i)
{
for(x=0;x<i;++x)
{
printf("%i",i);
}
}
if(i=4)
{
for(;i>0;i--)
{
for(x=0;x<i;++x)
{
printf("%i",i);
}
}
}
return(0);
}

I have it down to output 1223334444555554444333221 and would like help on what conditional to have the newline come into play, I have tried different clauses but no luck. There has to be one person to steer me into the right place. Thanks

Code:

#include <stdio.h>

#define HEHE 5

int main()
{
	int i;
	int j;
	for (i = 0; i < HEHE; i++)
	{
		for (j = 0; j <= i; j++)
		{
			printf("%d", i + 1);
		}
		printf("\n");
	}
	for (i = HEHE - 1; i >= 0; i--)
	{
		for (j = 0; j < i; j++)
		{
			printf("%d", i);
		}
		printf("\n");
	}
	return 0;
}

Code:

#include <stdlib.h>

main()
{
 int i,x,x1,d;
   for(i=0;i<=5;++i)
   {
                    for(x=0;x<i;++x)
                    {
                    printf("%i",i);
                    }
   }
 if(i=4)
 {
  for(;i>0;i--)
  {
                    for(x=0;x<i;++x)
                    {                   
                    printf("%i",i);
                    }
  }
 }
 return(0);
}

sorry is that better for you, and sorry I don't have the highest grammer but dubious I have no idea what that means......thanks for your help?

well update I have fixed my problem. I even stoped it from \n the empty space. I kinda agree with Salem with blurting the answer, all you had to say if something along the lines of in which /n dictates the numbers value not amount. Well just to finish the thread I will post my code with my own updated tweak to it.

Code:

#include <stdlib.h>

main()
{
 int i,x,x1,d;
   for(i=0;i<=5;++i)
   {
                    for(x=0;x<i;++x)
                    {
                    printf("%i",i);
                    }
                                    if(i>0)
                                    {
                                    printf("\n");
                                    }
   }
 if(i=4)
 {
  for(;i>0;i--)
  {
                    for(x=0;x<i;++x)
                    {                   
                    printf("%i",i);
                    }
  printf("\n");
 
 }
}
scanf("%s",x1);
 return(0);
}

wait salem should it? I have never had that error, I use the bloodshed Dev-C++ complier.

i'm not good at english, you may not understand the words i written,so i thinked the code is the best way to express my thought.

sorry, i will do my best to explain , and not just post the code

I wrote out the if in my code. I would just like to know A. What is the difference between = and ==. B logicaly why that is. Please dont post use google its just rude.

in my compilation, it gives four warnings

This is the assignment operator: =
This is the comparison operator: ==

printf and scanf are in <stdio.h>, not <stdlib.h>.
d is not used anywhere.
x1 is an int, your scanf call uses %s with it -- %d is for ints -- and the corresponding argument should then be &x1.

do you know chinese?
