C program for Floyd’s triangle Number pattern using nested for

C program for Floyd’s triangle Number pattern using nested for

In this tutorial, we will discuss C program for Floyd’s triangle Number pattern using nested for

In C language, we will discuss about Floyd’s triangle Number pattern using nested for in C programming language.

In C language, we can display many shapes such as Floyd’s triangle ,pyramids, rectangles and squares etc…

In this post, we display floyd’s triangle number pattern using Nested for loop in C language

Program to print triangle pattern using number

Code to floyd’s triangle pattern 1

Program 1

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

int main()
{
    int num,i,j;
    printf("Enter number of rows");
    scanf("%d",&num);
    for(i=1; i<=num; i++){
        for(j=1; j<=i; j++){
                printf("%d",j);
    }
     printf("\n");
    }
    getch();
    return 0;
}

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

Enter number of rows
7
1
12
123
1234
12345
123456
1234567

Program 2

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

int main()
{
    int num,i,j;
    printf("Enter number of rows\n");
    scanf("%d", &num);
    for(i=1; i<=num; i++){
        for(j=1; j<=i; j++){
        printf("%d",i);
    }
    printf("\n");
    }
    getch();
    return 0;
}

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

Enter number of rows
7
1
22
333
4444
55555
666666
7777777

Program 3

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

int main()
{
    int rows,i,j;
    printf("Enter number of rows\n");
    scanf("%d", &rows);
    for(i=rows; i>=1; i--){
        for(j=1; j<=i; j++){
        printf("%d",j);
    }
    printf("\n");
    }
    getch();
    return 0;
}

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

Enter number of rows
7
1 2 3 4 5 6 7
1 2 3 4 5 6
