In this tutorial, we will discuss how to write following C program to triangle number pattern
Here, some of Floyd’s triangle number patterns are written using nested for loop in C language
Program 1
#include <stdio.h>
#include <stdlib.h>
int main()
{
int rows;
printf("Triangle pattern 1\n\n");
printf("Enter the rows: ");
scanf("%d",&rows);
int i,j;
for(i=1; i<=rows; i++)
{
for(j=i; j<=rows; j++)
{
printf("%d",i);
}
printf("\n");
}
getch();
return 0;
}
When the above code is executed, it produces the following results:
11111111 2222222 333333 44444 5555 666 77 8
Program 2
#include <stdio.h>
#include <stdlib.h>
int main()
{
int rows;
printf("Triangle pattern 1\n\n");
printf("Enter the rows: ");
scanf("%d",&rows);
int i,j;
for(i=1; i<=rows; i++)
{
for(j=i; j<=rows; j++)
{
printf("%d",j);
}
printf("\n");
}
getch();
return 0;
}
When the above code is executed, it produces the following results:
12345678 2345678 345678 45678 5678 678 78 8
Program 3
#include <stdio.h>
#include <stdlib.h>
int main()
{
int rows;
printf("Triangle pattern 3\n\n");
printf("Enter the rows: ");
scanf("%d",&rows);
int i,j,k;
for(i=rows; i>=1; i--)
{
if(i%2==1){k=1;
}
else {k=i;}
for(j=1; j<=i; j++)
{
printf("%d",k);
if(i%2==1){k++;}
else {k--;}
}
printf("\n");
}
getch();
return 0;
}
When the above code is executed, it produces the following results:
87654321 1234567 654321 12345 4321 123 21 1
Program 4
#include <stdio.h>
#include <stdlib.h>
int main()
{
int rows, i,j,k=1;
printf("Enter the rows for pattern: ");
scanf("%d",&rows); //input from user
printf("here your pattern\n");
for(i=1; i<=rows; i++){ //for rows
for(j=1; j<=i; j++){
printf("%d",k);
k++;
}
k--;
for(j=1; j<=i-1; j++){
k--;
printf("%d",k);
}
printf("\n");
k=1;
}
getch();
return 0;
}
When the above code is executed, it produces the following results:
Enter the rows for pattern:9 here your pattern 1 121 12321 1234321 123454321 12345654321 1234567654321 123456787654321 12345678987654321
