Alphabet Pyramid pattern in C using while loop

Alphabet Pyramid pattern in C using while loop

In this tutorial, we will discuss the Alphabet Pyramid pattern in C using while loop

Alphabet Pyramid pattern in C using the while loop

In this program, we are going to learn about how to display  Alphabet pyramid pattern  using while loop  in C programming language

Here, we display an Alphabet pyramid pattern program with coding using nested while loop and also we get input from the user using scanf() function in C language

The user can provide numbers as they wish and get the  Alphabet pyramid pattern according to their input.

Program 1

Alphabet pyramid pattern 1

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int i,j,rows;
    printf("Enter the number of rows\n");
    scanf("%d",&rows);//get input from user
    i=1;
while(i<=rows){
j=1;
  while(j<=rows-i){
  printf(" ");//print space
  j++;
  }


   j=1;
   while(j<=i){//print left side pattern
  printf("%c",(char)(j+64));
   j++;
    }

   j=i-1;
   while(j>=1){//print right side pattern
  printf("%c",(char)(j+64));
   j--;
}
i++;
printf("\n");// move to next line
}
getch();
return 0;
}

When the above code is executed, it produces the following results

Enter the number of rows
6
          A
        ABA
      ABCBA
    ABCDCBA
  ABCDEDCBA
ABCDEFEDCBA

Alphabet pyramid pattern 2

Program 2

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int i,j,rows;
    printf("Enter the number of rows\n");
    scanf("%d",&rows);
    i=1;
while(i<=rows){
j=1;
  while(j<=rows-i){
  printf(" ");//print space
  j++;
  }


   j=i;
   while(j>0){
  printf("%c",(char)(j+64));//print left side pattern
   j--;
    }

   j=2;
   while(j<=i){
 printf("%c",(char)(j+64));//print right side pattern
   j++;
}
i++;
printf("\n");
}
getch();
    return 0;
}

When the above code is executed, it produces the following results

Enter the number of rows
6
          A
        BAB
      CBABC
    DCBABCD
  EDCBABCDE
FEDCBABCDEF

Alphabet pyramid pattern 3

Program 3

#include <stdio.h>
#include <stdlib.h>

int main()
{
     int i,j,rows;
    printf("Enter the number of rows\n");
    scanf("%d",&rows);

i=1;
while(i<=rows){
j=1;
  while(j<=rows-i){
  printf(" ");
  j++;
  }


   j=1;
   while(j<=i){
  printf("%c",(char)(j+64));
  printf(" ");
   j++;
    }
    i++;
    printf("\n");
}
    return 0;
}

When the above code is executed, it produces the following results

Enter te number of rows
6
          A
        A B
      A B C
    A B C D 
  A B C D E
A B C D E F 

Alphabet pyramid pattern 4

Program 4

#include <stdio.h>
#include <stdlib.h>

int main() {
    int i,j,rows;
    printf("Enter the number of rows\n");
    scanf("%d",&rows);
    i=1;
    while(i<=rows)
        {
            j=1;
    while(j<=rows-i){
            printf(" ");
    j++; }
    j=1;
    while(j<=i){
            printf("%c",(char)(i+64));
    printf(" ");
    j++; }
    i++;
    printf("\n");
    }
    getch();
    return 0; }

When the above code is executed, it produces the following results

Enter the number of rows
6
          A
        B B
      C C C
    D D D D
   E E E E E
  F F F F F F

Alphabet pyramid pattern 5

Program 5

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int i,j,rows;
    printf("Enter the number of rows\n");
    scanf("%d",&rows);

i=rows;
while(i>=1){
j=1;
  while(j<=rows-i){
 printf("  ");
  j++;
  }


   j=1;
   while(j<=2*i-1){
       if(j<=i){
  printf("%c",(char)(j+64));
  printf(" ");
       }
      else{
          printf("%c",(char)(2*i-j+64));
          printf(" ");
      }
   j++;
    }
    i--;
    printf("\n");
}
getch();
    return 0;
}

When the above code is executed, it produces the following results

Enter the  number of rows
5
A B C D E D C B A
    A B C D C B A
        A B C B A
            A B A
                A
