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 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
