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.

#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");
 }
