C program to Floyd’s triangle star pattern

In this tutorial, we will discuss the C program to Floyd’s triangle star pattern.

This post to described how to create Floyd’s triangle star pattern using nested for loop in C language

Program 1

Code to Floyd’s triangle star pattern 1

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int i,j,rows;
    printf("Enter number of rows you want: ");
    scanf("%d",&rows);//Input number of rows from user

    for(i=1; i<=rows; i++){//parent for loop for literate rows

            for(j=i; j<rows; j++){//print space using this for loop
                printf(" ");
            }

            for(j=1; j<=i; j++)//print star through every rows
            {
                printf("*");
            }
            printf("\n"); //move to next line

    }
     getch();
    return 0;
}

When the above code is executed, it produces the following results:

Program 2

Code to Floyd’s triangle star pattern 2

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int i,j,rows;
    printf("Enter number of rows you want: ");
    scanf("%d",&rows);//Input number of rows from user

    for(i=1; i<=rows; i++){//parent for loop for literate rows

            for(j=1; j<=i; j++){//print star for pattern
                    printf("*");
            }
            printf("\n"); //move to next line

    }
     getch();
    return 0;
}

When the above code is executed, it produces the following results:

Program 3

Code to Floyd’s triangle star pattern 3

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int i,j,rows;
    printf("Enter number of rows you want: ");
    scanf("%d",&rows);//Input number of rows from user

    for(i=1; i<=rows; i++){//parent for loop for literate rows

            for(j=i; j<=rows; j++){//print star for pattern
                    printf("*");
            }
            printf("\n"); //move to next line

    }
     getch();
    return 0;
}

When the above code is executed, it produces the following results:

Program 4

Code to Floyd’s triangle star pattern 4

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int i,j,rows;
    printf("Enter number of rows you want: ");
    scanf("%d",&rows);//Input number of rows from user

    for(i=1; i<=rows; i++){//parent for loop for literate rows

            for(j=1; j<=i; j++){//print star for pattern
                    printf(" ");
            }
            for(j=i; j<=rows; j++){//print star for pattern
                    printf("*");
            }
            printf("\n"); //move to next line

    }
     getch();
    return 0;
