C++ program to print a diamond inside a box using asterisks.

#include<math.h>
void main()
{
int i=0,j=0,num;
clrscr();
cout<<"Enter limit\n";
cin>>num;
cout<<endl;
for(i=-(num+2);i<=num+2;i++)
{
for(j=-(num+2);j<=num+2;j++)
{
if(abs(i)+abs(j)<=num||j==-(num+2)
||j==(num+2)||i==-(num+2)||i==(num+2))
{
cout<<"*";
}
