Program to print chessboard pattern in C++

#include<iostream>

using namespace std;

int main() {
	int size = 8;
	
	for(int i=0; i<size; i++) {
		for(int j=0; j<size; j++) {
			if((i+j)%2 == 0)
				cout<<"#";
			else
				cout<<" ";
		}
		cout<<"\n";
	}
	return 0;
}

Output

# # # # 
 # # # #
# # # # 
 # # # #
# # # # 
 # # # #
# # # # 
 # # # #

So, in this code, we are running two loops, one to control rows and another to columns. Then we are simply checking the alteration using the positions. When both i+j are even, then we substitute # otherwise we print a space character.
