### Even Odd Number Star Pyramid

Q. Write a C program to print the following even odd number star pyramid as:

1
*2
1*3
*2*4
1*3*5
*2*4*6

Ans.

/*odd even number star pyramid C program*/
#include<stdio.h>
int main()
{
int num,r,c,z;
printf("Enter no. of rows : ");
scanf("%d", &num);
for(r=1; r<=num; r++)
{
for(c=1,z=r; c<=r; c++,z--)
{
if(z%2==0)
printf("%d",c);
else
printf("*");
}
printf("\n");
}
getch();
return 0;
}

The output of above program would be:

1. 1
3*2
4*5*6
10*9*8*7
11*12*13*14*15

1. its java code you have to convert it in c

package Triangle;

import java.util.Scanner;

public class Prg48 {

/**
* @param args
*/
public static void main(String[] args) {
int i,j,no,d=1,c=1;
Scanner sc = new Scanner(System.in);
no = sc.nextInt();

for(i=1;i<=no;i++)
{
if(i%2==0)
{
c=c+i;
d=c+1;
if(i>2)
{
c=c*2;
d=c+1;
}
for(j=1;j<=i*2-1;j++)
{
if(j%2==0)
{
System.out.print("*");
}
else
{
System.out.print(c);
c--;
}
}
System.out.println();
}
else
{
for(j=1;j<=i*2-1;j++)
{
if(j%2==0)
{
System.out.print("*");
}
else
{
System.out.print(d);
d++;
}
}
System.out.println();
}
}
}
// TODO Auto-generated method stub

}

please provide program for this star pattern?

1. @ Arundhati Saxena,

Your required star pattern C program source code as:

3. Plz print
××××××
×××
×

1. Your required symbol hash pattern C program source code as:

#include"stdio.h>
int main()
{
int n=6,r,c;
for(r=1; r<=3; r++,n=n-3)
{
for(c=1; c<=n; c++)
printf("*");
printf("\n");
}
printf("#");
getch();
return 0;
}

/****************Output****************/

4. Plz print
×××××
×××
×

5. Plz print
×
×××
