Q-10: Write a C/C++ program to print a triangle of asterisks(*) as follows (take number of lines from user as input):
*
* * *
* * * * *
* * * * * * * 
    
Using - C

  
  

    
      #include<stdio.h>
      void main() {
        int n, i, j;
        printf("Enter the number of lines(rows):  ");
        scanf("%d",&n);
        
        for(i=1; i <= n*2; i+=2){
          for(j=1; j <= i; j++){
            printf("* ");
          }
        printf("\n");
        }	
      }

OUTPUT

Enter the number of lines(rows):  4

              for(int i=1; i <= n*2; i+=2){
                for(int j=1; j <= i; j++){
                  cout<<"* ";

              }
                
            return 0;
            }

OUTPUT

Enter the number of lines(rows):  3
