### 13. Design numbers tringle pyramid

Q. Write a program to generate a following numbers triangle:(Where user entered number through keyboard, for example if num=5)

54321
4321
321
21
1
Ans.
/*c program for number triangle pyramid*/

#include<stdio.h>
#include<conio.h>
int main()
{
int num,c;
printf("Enter loop repeat number(rows): ");
scanf("%d",&num);
for(; num>=1; num--)
{
for(c=num; c>=1; c--)
printf("%d",c);
printf("\n");
}
getch();
return 0;
}

/*************OUTPUT****************
Enter loop repeat number(rows): 5

54321
4321
321

5. I want the same program by using while loop

1. Above number triangle pyramid using while loop source code as:

#include"stdio.h"
#include"conio.h"
int main()
{
int num,c;
printf("Enter loop repeat number(rows): ");
scanf("%d",&num);
while(num>=1)
{
c=num;
while(c>=1)
{
printf("%d",c);
c--;
}
num--;
printf("\n");
}
getch();
return 0;
}
