Answer 1

Output:

C Program:

#include<stdio.h>
int main()
{
   int n,i,j;
   printf("enter a number: ");
   scanf("%d",&n);//read number from user
   for(i=1;i<=n;i++)
   {
       for(j=1;j<=i;j++)
           printf("* ");//print asterisks in based on line number
       printf("\n");//next line
   }
}

C++ Program:

#include<iostream>
using namespace std;
int main()
{
   int n,i,j;
   cout<<"enter a number: ";
   cin>>n;//read number from user
   for(i=1;i<=n;i++)
   {
       for(j=1;j<=i;j++)
           cout<<"* ";//print asterisks in based on line number
       cout<<endl;//next line
   }
}
