After a few minutes of doing them, I got kind of bored
and made a quick program to make punnett squares for me, as well as analyze the punnet square. Later I added more functions to make things easier for me.I just wanted to post it here to get a critique of my code, I'm kind of just starting out so I wanted to know how I'm doing. Don't take it easy on me though.
Here's the code:
Code:
#include <iostream>
using namespace std;
void boxes(char a, char b, char c, char d);
void analyze(char a2, char b2, char c2, char d2);
int main()
{
char a1,a2,a3,a4,resp;
resp = 'y';
cout<<"Punnet Squarer\n V1.0"<<endl;
while(resp == 'y'){
cout<<"enter first letter for top row A/a"<<endl;
cin>>a1;
cout<<"enter second letter for top row A/a"<<endl;
cin>>a2;
cout<<"enter first letter for side column A/a"<<endl;
cin>>a3;
cout<<"enter second letter for side comumn A/a"<<endl;
cin>>a4;
boxes(a1,a2,a3,a4);
analyze(a1,a2,a3,a4);
cout<<"\n\n";
cout<<"do another punnett square? y/n"<<endl;
cin>>resp;
}
return 0;
}
void boxes(char a, char b, char c, char d) {
if(a=='a' && c=='A'){
a='A';
c='a';
}
if(b=='a' && c=='A'){
b='A';
c='a';
}
if(a=='a' && d=='A'){
a='A';
d='a';
}
if(b=='a' && d=='A'){
b='A';
d='a';
}
cout<<"\n\n";
cout<<" ";
cout<<a<<c;
cout<<" ";
cout<<"|";
cout<<" ";
cout<<b<<c;
cout<<endl;
cout<<" ";
cout<<"--------"<<endl;
cout<<" ";
cout<<a<<d;
cout<<" ";

cout<<endl;
