Question

Help with a C code!

Multidimensional Array problem:

a)
prompt the user for the number of rows they want. Then, print an array of stars.

For example, if user prompts "5", the output should look like:

*
* *
* * *
* * * *
* * * * *

b)

Do the same, but inverse the table.
If user types 5 for their prompt, output will look like:

* * * * *
* * * *
* * *
* *
*

Please help me write this code! I'm having troubles with multidimensional array coding for C

Thanks!

Answer 1

THE PROGRAM IS WRITTEN IN C.

ANS a.

SOURCE CODE:

#include<stdio.h>
int main()
{
   int n,i=0,j;
   scanf("%d",&n);
   for(i=1;i<=n;i++) /*this will run eqauls number of row*/
   {
       for(j=1;j<=i;j++) /*this for loop will run only till it prints '* ' equal to row number */
       {
           printf("* ");
       }
       printf("\n");
   }
   return 0;
}

OUTPUT:

5
*
* *
* * *
* * * *
* * * * *

ANS B.

SOURCE CODE:

#include<stdio.h>
int main()
{
   int n,i=0,j;
   scanf("%d",&n);
   for(i=1;i<=n;i++) /*this will run eqauls number of row*/
   {
       for(j=i;j<=n;j++) /*this for loop will run print * for the first equal to number of number and then drecreases by 1 each step */
       {
           printf("* ");
       }
       printf("\n");
   }
   return 0;
}

OUTPUT:
