In this tutorial, we will write a C program to print half Pyramid using alphabets/characters. Before that, you may go through the following topic in C.

Pattern 1: C program for character/alphabet.

Enter the no. of rows: 6
F F F F F F
E E E E E
D D D D
C C C
B B
A

Source code:

#include <stdio.h>

void main()
{
   int i, j, rows;

   printf("Enter the no. of rows: ");
   scanf("%d", &rows);

   for (i = 1; i <= rows; i++)
   {
      for (j = i; j <= rows; j++)
         printf("%c ", (char)(i + 64));

      printf("\n");
   }
}

Pattern 2: C program for character/alphabet.

Enter the no. of rows: 5
A A A A A
B B B B
C C C
D D
E

Source code:

#include <stdio.h>

void main()
{
   int i, j, rows;

   printf("Enter the no. of rows: ");
   scanf("%d", &rows);

   for (i = rows; i >= 1; i--)
   {
      for (j = 1; j <= i; j++)
         printf("%c ", (char)(i + 64));

      printf("\n");
   }
}

Pattern 3: C program for character/alphabet.

Enter the no. of rows: 5
A B C D E
A B C D
A B C
A B
A

Source code:

#include <stdio.h>

void main()
{
   int i, j, rows;

   printf("Enter the no. of rows: ");
   scanf("%d", &rows);

   for (i = 1; i <= rows; i++)
   {
      for (j = 1; j <= rows - i + 1; j++)
         printf("%c ", (char)(j + 64));

      printf("\n");
   }
}

Pattern 4: C program for character/alphabet.

Enter the no. of rows: 5
E D C B A
D C B A
C B A
B A
A

Source code:

#include <stdio.h>

void main()
{
   int i, j, rows;

   printf("Enter the no. of rows: ");
   scanf("%d", &rows);

   for (i = rows; i >= 1; i--)
   {
      for (j = i; j >= 1; j--)
         printf("%c ", (char)(j + 64));

      printf("\n");
   }
}

Pattern 5: C program for character/alphabet.

Enter the no. of rows: 5
E F G H I
D E F G
C D E
B C
A

Source code:

#include <stdio.h>

void main()
{
   int rows, k, i, j;

   printf("Enter the no. of rows: ");
   scanf("%d", &rows);

   for (i = rows; i >= 1; i--)
   {
      k = i;

      for (j = 1; j <= i; j++, k++)
         printf("%c ", (char)(k + 64));

      printf("\n");
   }
}

Pattern 6: C program for character/alphabet.

Enter the no. of rows: 5
E D C B A
E D C B
E D C
E D
E

Source code:

#include <stdio.h>

void main()
{
   int rows, i, j;

   printf("Enter the no. of rows: ");
   scanf("%d", &rows);

   for (i = 1; i <= rows; i++)
   {
      for (j = rows; j >= i; j--)
         printf("%c ", (char)(j + 64));

      printf("\n");
   }
}

Pattern 7: C program for character/alphabet.

Enter the no. of rows: 5
A B C D E
B C D E
C D E
D E
E

Source code:

#include<stdio.h>

void main()
{
    int rows, i, j;

    printf("Enter the no. of rows: ");
    scanf("%d",&rows);

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