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
