Question

C++

Write a program that asks for a number and then prints as many lines as the user inputs. Each line contains as many pairs of characters ("*#") as the number of this line. It should look like the right half of a pyramid. Your version of the program must print the same result as the expected output. To to this lab, you must use two do-while loops.

Two exceptions:

When the user inputs a number less than 1, then the program writes only one line.

When the user inputs a number greater than 20, then the program writes only twenty lines.

#include <stdio.h>

int main()

{

/* your code */

return 0;

}

Example input Example output *tt * # * # * # * #

Answer 1

#include <stdio.h>

int main()
{
   int n, i, j;
   scanf("%d", &n);
   if(n < 1) {
      n = 1;
   } else if(n > 20) {
      n = 20;
   }
   i = 0;
   do {
      j = 0;
      do {
         printf("*#");
         j++;
      } while(j <= i);
      printf("\n");
      i++;
   } while(i < n);
   return 0;
}
