C program to print Floyd’s triangle alphabet pattern

C program to print Floyd’s triangle alphabet pattern

In this tutorial, we will discuss the concept of C program to print Floyd’s triangle alphabet pattern

In this post, we will learn how to displayed  Floyd’s triangle alphabet pattern  using for loop or nested for loop in C programming language

here, we displayed 8 alphabet Floyd’s triangle program with coding using nested for loop and also we get input from user using scanf() function in C

the user can provide numbers as they wish and get the alphabet pattern according to their input

Program 1

Floyd’s triangle alphabet pattern 1

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

int main()
{
    int i,j,rows;
    char alphabet='A';
    printf("Enter number of rows to pattern: ");
    scanf("%d",&rows);
 printf("\n");
    for(i=1; i<=rows; i++){
        for(j=1; j<=i; j++){
          printf("%c",alphabet++);
        }
        printf("\n");
    }
    printf("\nHere, your pattern is printed");
    getch();
    return 0;
}

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

Enter number of rows to pattern: 6

A
BC
DEF
GHIJ
KLMNO
PORSTU

Here, your pattern is printed

 

Program 2

Floyd’s triangle alphabet pattern 2

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

int main()
{
    int i,j,rows,num,count;
    char alphabet='A';
    printf("Enter number of rows to pattern: ");
    scanf("%d",&rows);
 printf("\n");
    for(i=1; i<=rows; i++){
            num=rows-1;
    count=i;
        for(j=1; j<=i; j++){
          printf("%2c",(char)(count+64));
          count=count+num;
          num--;
        }
        printf("\n");
    }
    printf("\nHere, your pattern is printed");
    getch();
    return 0;
}

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

Enter number of rows to pattern: 6

A
B G
C H L
D I M P
E J N Q S
F K o R T U

Here, your pattern is printrd

 

Program 3

Floyd’s triangle alphabet pattern 3

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

int main()
{
    int i,j,rows;
    printf("Enter the number of rows: ");
    scanf("%d",&rows);
    printf("\nyour pattern here\n\n");
    for(i=0; i<=rows; i++){
        for(j=i; j<=rows; j++){
        printf("%c",(char)(j+65));
    }
    printf("\n");
    }
getch();
    return 0;
}

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

Enter the number of rows: 6

Program 4

Floyd’s triangle alphabet pattern 4

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

int main()
{
    char web[]="Code4coding";
    int i,j;
    for(i=0; web[i]; i++){
        for(j=0; j<=i; j++){
                printf("%c",web[j]);

    }
     printf("\n");
    }
    return 0;
}

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

int main()
{
    int i,j,k,rows;
    printf("Enter the number of rows: ");
    scanf("%d",&rows);
    printf("\nyour pattern here\n\n");
    for(i=1; i<=rows; i++){
        for(j=1; j<=rows-i; j++){
                printf(" ");
        }
        for(k=1; k<=i; k++){
        printf("%c",(char)(j+64));
    }
    printf("\n");
    }
