Program description:-

In today’s tutorial, we will create a program, that will print a Right Arrow Star Pattern using nested for loops. First, we will be taking the size in form of rows from the user. Then we will use nested for loops to create a pattern looking like the Right Arrow symbol. Then we will print the pattern using the printf() function.

Below is an example of Print Right Arrow Star Pattern.

Program Code:-

#include<stdio.h>
int main()
{
    //declaring the required variables for the program.
 	int i, j, rw; 
 	//i,j = it will hold the integer value to control the loop.
 	//rw = it will hold the input rows from the user
 	//Taking the input number of rows from the user.
 	printf("Enter Right Arrow Star Pattern Rows =  ");
 	scanf("%d", &rw);//Scanning the input rows
    //Generating the pattern using star
    printf("Right Arrow Star Pattern\n");
	for(i = 1; i <= rw; i++)
	{
        for(j = 1; j <= rw; j++)
        {
            if(j < i)
            {
                printf(" ");
            }
            else
            {
                //Printing the right arrow using the star
                printf("*");
            }
        }
		printf("\n");
	}

    for(i = 1; i <= rw; i++)
	{
		for(j = 1; j <= rw; j++)
		{
            if(j < rw - i)
            {
                printf(" ");
            }
            else
            {
                printf("*");
            }		
		}
		printf("\n");
	}
 	return 0;
}

#include<stdio.h>

int main()

{

//declaring the required variables for the program.

int i, j, rw;

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

//rw = it will hold the input rows from the user

//Taking the input number of rows from the user.

printf("Enter Right Arrow Star Pattern Rows = ");

scanf("%d", &rw);//Scanning the input rows

//Generating the pattern using star

printf("Right Arrow Star Pattern\n");

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

{

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

{

if(j < i)

{

printf(" ");

}

else

{

//Printing the right arrow using the star

printf("*");

}

printf("\n");

}

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

{

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

{

if(j < rw - i)

{

printf(" ");

}

else

{

printf("*");

}

printf("\n");

}

return 0;

}

Output:-

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

rw = it will hold the integer value.
j = it will hold the integer value.
i = it will hold the integer value.

STEP 1: START the program

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 Floyd's

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 the program

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 Floyd's

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:-
