Number Character Triangle

Posted: 21 Apr 2013 11:41 AM PDT

Q. Write a C program to print the following number character pyramid as:

1
21A
321AB
4321ABC
54321ABCD

Ans.

/*c program for number character triangle*/
#include<stdio.h>
int main()
{
 int num,r,c,p,z;
 printf("Enetr no. of rows : ");
 scanf("%d", &num);
 for(r=1; r<=num; r++)
 {
  for(c=r; c>=1; c--)
      printf("%d",c);
  for(z='A',p=r; p>1; p--,z++)
      printf("%c",z);
  printf("\n");
 }
 getch();
 return 0;
}

The output of above program would be:

 {
  for(c=0,s=r; c<=r; c++,s--)
     printf(" %d",s);
  for(q=1; q<=r; q++)
     printf(" %d",q);
  printf("\n");
 }
 getch();
 return 0;
}

 static char ch='A';
 printf("Enter no. of rows : ");
 scanf("%d", &num);
 for(r=1; r<=num; r++)
 {
  for(c=1; c<=r; c++)
  {
    if(r%2==0)
       printf(" %c",ch++);
    else
       printf(" %d",i++);
  }
  printf("\n");
 }

 for(r=1; r<=num; r++)
 {
   for(c=1; c<=r; c++)
   {
     if(r%2==0)
        printf(" $");
     else
        printf(" *");
   }
   printf("\n");
 }

Ans.

/*c program for character and star pyramid*/
#include<stdio.h>
int main()
{
 char ch,r,c,q;
 printf("Enter ending character : ");
 scanf("%c", &ch);
 if(ch>='a' && ch<='z')
    ch=ch-32;
 for(r='A'; r<=ch; r++)
 {
  for(c='A'; c<=r; c++)
  {
    if(r%2==0)
       printf("*");
    else
       printf("%c",c);
  }
  printf("\n");
 }
 for(q=ch-1; q>='A'; q--)
 {
  for(c='A'; c<=q; c++)
  {
    if(q%2==0)
       printf("*");
    else
       printf("%c",c);
  }
  printf("\n");
 }
 getch();
 return 0;
