C Program to Print Same Alphabet in each Right Triangle Column

Write a C Program to Print Same Alphabet in each Right Triangle Column using for loop. Or, Write a C program to print the repeated characters or same alphabets in each right triangle column using for loop.

#include <stdio.h>

int main()
{
    int i, j, rows, alphabet = 65;
    
    printf("Enter Right Triangle Columns with Same Alphabets Rows = ");
    scanf("%d",&rows);

    printf("Right Triangle Columns with Same Alphabets Pattern\n"); 
    
	for (i = 0 ; i < rows; i++ ) 
	{
		for (j = 0 ; j <= i; j++ ) 	
		{
			printf("%c ", alphabet);
		}
		alphabet++;
		printf("\n");
	}

    return 0;
}
C Program to Print Same Alphabet in each Right Triangle Column

This C alphabets pattern example displays the right triangle pattern of repeated characters in each column using a while loop.

#include <stdio.h>

int main()
{
    int i = 0, j, rows, alphabet = 65;
    
    printf("Enter Right Triangle Columns with Same Alphabets Rows = ");
    scanf("%d",&rows);

    printf("\nRight Triangle Columns with Same Alphabets Pattern\n"); 
    
	while ( i < rows ) 
	{
		j = 0 ;
		while( j <= i) 	
		{
			printf("%c ", alphabet);
			j++ ;
		}
		alphabet++;
		printf("\n");
		i++;
	}

    return 0;
}
Enter Right Triangle Columns with Same Alphabets Rows = 12

C program to print the same alphabets in every right Triangle row-column using a do while loop.

#include <stdio.h>

int main()
{
    int i = 0, j, rows, alphabet = 65;
    
    printf("Enter Right Triangle Columns with Same Alphabets Rows = ");
    scanf("%d",&rows);

    printf("\nRight Triangle Columns with Same Alphabets Pattern\n"); 
    
	do 
	{
		j = 0 ;
		do	
		{
			printf("%c ", alphabet);

		} while( ++j <= i);
		alphabet++;
		printf("\n");

	} while ( ++i < rows );

    return 0;
}
Enter Right Triangle Columns with Same Alphabets Rows = 15
