C Program to Print Triangle Alphabets Pattern

Prerequisites

Before starting with this tutorial we assume that you are best aware of the following C programming topics:

Operators in C Programming.

Basic Input and Output function in C Programming.
Basic C programming.
While loop in C programming.

Conditional Statements in C programming.

Algorithm:-

1. Declaring the required variables for the program.

2. Taking the input rows of the right-angled from the user.

3. Generating the Alphabets  pattern using the nested while loop.

4. Printing the triangle pattern.

5. End the program.

1. Declaring the required variables for the program.

2. Taking the input rows of the right-angled from the user.

3. Generating the Alphabets pattern using the nested while loop.

5. End the program.

Program description that will print the Triangle Alphabets Pattern:-

In today’s tutorial, we will create a program, that will print the Triangle Alphabets Pattern using a while loop taking the rows from the user. First, take the input number of rows in the triangle by the user. Then we will print the simple right-angle triangle of Alphabets using the for-loop. The below is an example to print a Triangle Alphabets Pattern.

Program Code:-

/* C Program to Print Triangle Alphabets Pattern */
#include <stdio.h>
int main() 
{
   //declaring the required variables for the program
   int i, j;
   char rw, alp = 'A';
    //i = it will hold the integer value to control the loop. 
  	//j = it will hold the integer value to control the loop. 
  	//rw = it will hold the character value for number of rows.
  	//rw = it will hold the character value.
	//taking the input number of rows from the user
   printf("Enter an uppercase character you want to print in the last row: ");
   scanf("%c", &rw);
    //Generating the  right angled triangle.
   for (i = 1; i <= (rw - 'A' + 1); ++i) {
      for (j = 1; j <= i; ++j) {
         //printing the right angled triangle filled with alphabets
         printf("%c ", alp);
      }
      ++alp;
      printf("\n");
   }
   return 0;
}

/* C Program to Print Triangle Alphabets Pattern */

#include <stdio.h>

int main()

{

//declaring the required variables for the program

int i, j;

char rw, alp = 'A';

//i = it will hold the integer value to control the loop.

//j = it will hold the integer value to control the loop.

//rw = it will hold the character value for number of rows.

//rw = it will hold the character value.

//taking the input number of rows from the user

printf("Enter an uppercase character you want to print in the last row: ");

scanf("%c", &rw);

//Generating the right angled triangle.

for (i = 1; i <= (rw - 'A' + 1); ++i) {

for (j = 1; j <= i; ++j) {

//printing the right angled triangle filled with alphabets

printf("%c ", alp);

}

++alp;

printf("\n");

}

return 0;

}

Output:-

In the above program, we have Last initialized the required variable.

rw = it will hold the character value.
alp = it will hold the character value.
j = it will hold the integer value.

i = it will hold the integer value.

Input the number of rows for the pattern.
