Yes, many of us know how to do this. The question is: do you? Or can you figure it out?

If you need help, asking specific questions and posting code you've tried will get excellent answers.

Re: pascal triangle?

TRY THIS OUT

c Syntax (Toggle Plain Text)
#include<stdio.h>
main()
{
 int i,j,k;
 printf("\n");
 for(i=1;i<=10;i++)
 {
  for(j=1;j<=31-i;j++)printf(" ");
  for(j=i,k=(2*i-1)/2+1;k;j++,k--)
  {
    if(j==10)j=0;
    printf("%d",j);
  }
  for(j-=2,k=(2*i-1)/2;k;j--,k--)
  {
   if(j==-1)j=9;
   printf("%d",j);
  }
  printf("\n");
 }
}
#include<stdio.h>
main()
{
 int i,j,k;
 printf("\n");
 for(i=1;i<=10;i++)
 {
  for(j=1;j<=31-i;j++)printf(" ");
  for(j=i,k=(2*i-1)/2+1;k;j++,k--)
  {
    if(j==10)j=0;
    printf("%d",j);
  }
  for(j-=2,k=(2*i-1)/2;k;j--,k--)
  {
   if(j==-1)j=9;
   printf("%d",j);
  }
  printf("\n");
 }
}

TRY THIS OUT

goutham, around here we want the poster to find the answer. We help them with their code, we don't do their homework for them.

stringgader, read the above. In order to get this problem from your instructor, you must know something about code. This can't possibly be your first program.

Go back and read the thread link that I posted, it contains the answer to your problem. If you don't understand the posted code to that thread then I doubt you are ready for the course you are taking. The proglem is a little too advanced for someone completly new to programming and C language in particular.

Re: pascal triangle?

ei,, tnx again for your replies,,,
yup im only new to this, im already working on this for 2 weeks,, this is my code:

c Syntax (Toggle Plain Text)
#include<stdio.h>
int value,count1,count2,count3,temp;
main()
 {
 clrscr();
 temp=1;
                   printf("Enter number of rows:");
                   scanf("%d", &value);
 
 
 for(count1=1; count1<=value; count1++)
 printf(" ");
 {
  for(count2=value; count2>=count1; count2--)
  printf(" ");
  for(count3=1; count3<=temp; count3++)
  printf("%d",count1,count2,count3);
 printf("\n");
 temp+=2;
 }
 getche();
 }
#include<stdio.h>
int value,count1,count2,count3,temp;
main()
 {
 clrscr();
 temp=1;
                   printf("Enter number of rows:");
                   scanf("%d", &value);
 
 
 for(count1=1; count1<=value; count1++)
 printf(" ");
 {
  for(count2=value; count2>=count1; count2--)
  printf(" ");
  for(count3=1; count3<=temp; count3++)
  printf("%d",count1,count2,count3);
 printf("\n");
 temp+=2;
 }
 getche();
 }

but, my output is this:

C Syntax (Toggle Plain Text)
                 1
               222
              3333
             44444
            555555
etc......
                 1
               222
              3333
             44444
            555555
etc......

i bet i got a wrong formulation for this stuff, and my deadline is on saturday,, hoping 4 ur nice consideration... tnx alot

Re: pascal triangle?

@ stringgader. The code that goutham_see posted for you, works very well. Why don't you compare his with yours and learn what is not working with yours?.

In your last post I see that you make the declaration of variables ALL Global. I don't think that's what you want even when is going to work. What you want to do is to declare them after the left bracket in main, in this case.

The function:

Quote ...

clrscr();

is not necesary there. Is not doing anything for your, and above anything else, it makes your code not portable, which is something that you should always shoot for.

Same with

Quote ...

getche();

your could very well use the standard getchar().
