triangle number pattern using nested while in C

triangle number pattern Using nested while in C

In this tutorial ,we will learn about triangle Number pattern using nested while in C.

We can use nested while loop in C to write coding for Squares, rectangles, Floyed triangle ,Pyramid triangles and many other shapes.

In this tutorial, we will learn about Floyd’s triangle shapes and how to write coding for that, in the C programming language.

Program to print triangle pattern using number

Program 1

Floyd’s triangle number pattern 1

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

int main()
{
    int i=1;
    while(i<=10){//outer while loop
         int j=1;
        while(j<=i){//inner while loop
            printf("%d",j);//display on the screen
            j++;
        }
        printf("\n");//move to next line
        i++;
    }
getch();
    return 0;
}

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

1
12
123
1234
12345
123456
1234567
12345678
123456789
12345678910

 

Program 2

Floyd’s triangle number pattern 2

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

int main()
{
    int i=1;
    while(i<=9){//outer while loop
         int j=1;
        while(j<=i){//inner while loop
            printf("%d",i);//display on the screen
            j++;
        }
        printf("\n");//move to next line
        i++;
    }
    return 0;
}

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

1
22
333
4444
55555
666666
7777777
88888888
999999999

 

Program 3

Floyd’s triangle number pattern 3

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

int main()
{
    printf("floyd's triangle number pattern\n");
    printf("Enter the number of rows: \n");
    int rows;
    scanf("%d",&rows);//takes input from user
    int row=1;
    printf("Here your pattern \n\n");
    int i=1;
    while(i<=rows){//inner wile loop
        int j=1;
        while(j<=i){//outer while loop
            printf("%d",row);
            row++;
            j++;
        }
        printf("\n");//move to next line
        i++;
    }
getch();
    return 0;
}

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

floyd's triangle number pattern
Enter the number of rows:
6
Here your pattern

1
2 3
4 5 6
7 8 9 10
11 12 13 14 15
16 17 18 19 20 21

Program 4

Floyd’s triangle number pattern 4

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

int main()
{
    printf("floyd's triangle number pattern\n\n");
    int i=1,j,k,m1=10,num=0;
    while(i<=m1){
        int k=1;
        while(k<=m1-(m1-i)){
            printf(" ");
            k++;
        }
        num=m1-i;
        j=1;
        while(j<=num){
            printf("%d",m1-(m1-j));
            j++;
        }
        i++;
        printf("\n");//move to next line

    }
    getch();
    return 0;
}

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

1 2 3 4 5 6 7 8 9
   1 2 3 4 5 6 7 8
      1 2 3 4 5 6 7
         1 2 3 4 5 6
            1 2 3 4 5
               1 2 3 4
                  1 2 3
                     1 2
                        1
