Problem Statement:- Program to Print the Hollow Diamond Number Pattern.
Sample Input/Output:-
Data requirement:-
Input Data:- row_size
Output Data:- x
Additional Data:-out, in or inn(for python), print_control_x
Program in C
Here is the source code of the C Program to Print the Hollow Diamond Number Pattern.
Code:
#include<stdio.h>
int main()
{
printf("Enter the row size:");
int row_size;
scanf("%d",&row_size);
int in,out;
int print_control_x=row_size/2+1,x=1;
for(out=1;out<=row_size;out++)
{
for(in=1;in<=row_size;in++)
{
if(in==print_control_x || in==row_size-print_control_x+1)
{
printf("%d",x);
}
else
{
printf(" ");
}
}
if(out<=row_size/2){
print_control_x--;
x++;
}
else{
print_control_x++;
x--;
}
printf("\n");
}
}
Enter the row size:9
