C Program to Create Floyd’s Triangle

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.
For loop in C Programming.

Creating a Floyd’s:-

The C language is a very powerful programming language. In C programming we can perform many operations with the help of codings. The c language is very easy to create any shape. In this program, we will learn to create Floyd’s triangle with the help of some code.

Floyd’s triangle is a right-angled triangle that contains mathematical numbers from 1 and goes up to the required point.

Algorithm:-

STEP 1: START

STEP 2: first declare the variables

STEP 3: then start the parent for loop

STEP 4: now make the child for loop 

STEP 5: now use child loop to start drawing the <strong>Floyd's</strong>

STEP 6: Now this for loop will also execute under the parent for loop

STEP 7: Print "\n" for changing the line before the increment of the main loop

STEP 8: increment of the main for loop

STEP 9: return the zero value for main function

STEP 1: START

STEP 2: first declare the variables

STEP 3: then start the parent for loop

STEP 4: now make the child for loop

STEP 5: now use child loop to start drawing the <strong>Floyd's</strong>

STEP 6: Now this for loop will also execute under the parent for loop

STEP 7: Print "\n" for changing the line before the increment of the main loop

STEP 8: increment of the main for loop

STEP 9: return the zero value for main function

Program:-

To Create a Floyd’s Triangle

#include <stdio.h>  
int main()  
{  
    //variable declaration
    int num, i, j, k = 1;  
    //Taking the number of roes a input
    printf( " Enter the number of rows wanted in Floyd's triangle: \n");  
    scanf( "%d", &num);  
    // using nested for loop  
    // The main for loop define the rows and check rows condition  
    for (i = 1; i <= num; i++)  
    {  
        // Sub for loop check j should be less than equal to 1 and print the data.  
        for (j = 1; j <= i; j++)  
        {  
            printf(" %2d", k++); // printing the numbers  
        }  
        printf("\n");  
        }     
        return(0);   
}

#include <stdio.h>

int main()

{

//variable declaration

int num, i, j, k = 1;

//Taking the number of roes a input

printf( " Enter the number of rows wanted in Floyd's triangle: \n");

scanf( "%d", &num);

// using nested for loop

// The main for loop define the rows and check rows condition

for (i = 1; i <= num; i++)

{

// Sub for loop check j should be less than equal to 1 and print the data.

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

{

printf(" %2d", k++); // printing the numbers

}

printf("\n");

}

return(0);

}

Output:-

In the above program we have first initialized the required variable.

i = it will hold the integer value to control parent for loop.
j = it will hold the integer value to control child for loop.
k = it will hold the integer value to control child for loop.

num = it will hold the integer value for the number of rows.

Taking input Number of rows

Nested For loop the body of the program

Printing Numbers
