How to print diamond pattern in c++ & c...

Following is the program to print diamond using for loop in any programming language.

#include<iostream>

using namespace std;

int main()

{

int row,c,k,space=1;

cout<<"enter number of rows that you want to see=";

cin>>row;

space=row-1;

for(k=1;k<=row;k++)

{ //for loop to print space

for(c=1;c<=space;c++)

{

cout<<" ";

}

space--; //decrement the number of spaces by 1 each time

//for loop to print stars

for(c=1;c<=2*k-1;c++)

{

cout<<"*";

}

cout<<"\n";//move to the next line

}

//following will print second half of diamond

space=1;

//here we need to increment the space from 1 2 3 4 and so on

for(k=1;k<=row-1;k++)

{

for(c=1;c<=space;c++)

{

cout<<" ";

}

space++;// increment the number of space by 1 each time

for(c=1;c<=2*(row-k)-1  ;c++)

{

cout<<"*";

}

cout<<"\n";

}

return 0;

}
