Option Selection

[samrux]

I made an option selection program to use in my text game. It looks very simple, and it is (sort of), but expanding the options is extremely hard. I know it could be a lot better, so i came here.

I'll explain everything:

In my game, there are 2, 3 or 4 options to choose from to continue the game. In chapter 1, it's the main gameplay. It's always "Intro text" -> "ASCII image" -> "Outro text (sometimes)". So it's exactly what i did.

But, sometimes, when you have to test and investigate, some options dissapear when you already tried them. So i added a (very hard for me) way to completely ignore the option if you call the function with an option as "*". If you try to call it with 3 or 4 "*" options, it gives you an error. I added this feature just for fun.

So here are the arguments of the main function of the option selection:
void Main(bool IfNow, char Message1[99], char Message2[99], char Image[9999], char Op1[99], char Op2[99], char Op3[99], char Op4[99])

Boolean IfNow: If the function calling wants to show "now" in "What do you want to do"
Characterss Message1, 2 and Image: To know what to show when refreshing the screen.
Characters Op1, 2, 3 and 4: The options. As i explained, * makes it to ignore that option.


So again, I want to improve the way this works. Here is an example of what possibly can be greatly improved, the way the choosing works:

Position=1;
Choice=getch();
if(Choice=='s' || Choice=='S'){Choice=Position; return;}
else if(Choice==72){ //Up arrow key
    if(Position==1){ //Position 1
        if(Op4[0]=='*'){
            if(Op3[0]=='*'){Position=2;}
            else{Position=3;}
        }
        else{Position=4;}
    }
    else if(Position==2){ //Position 2
        if(Op1[0]=='*'){
            if(Op4[0]=='*'){Position=3;}
            else{Position=4;}
        }
        else{Position=1;}
    }
    else if(Position==3){ //Position 3
        if(Op2[0]=='*'){
            if(Op1[0]=='*'){Position=2;}
            else{Position=1;}
        }
        else{Position=2;}
    }
    else if(Position==4){ //Position 4
        if(Op3[0]=='*'){Position=4;}
        else{Position=3;}
    }
}
else if(Choice==80){ //Down arrow key
    if(Position==1){ //Position 1
        if(Op2[0]=='*'){
            if(Op3[0]=='*'){Position=4;}
            else{Position=3;}
        }
        else{Position=2;}
    }
    else if(Position==2){ //Position 2
        if(Op3[0]=='*'){
            if(Op4[0]=='*'){Position=1;}
            else{Position=4;}
        }
        else{Position=3;}
    }
    else if(Position==3){ //Position 3
        if(Op4[0]=='*'){
            if(Op1[0]=='*'){Position=2;}
            else{Position=1;}
        }
        else{Position=4;}
    }
    else if(Position==4){ //Position 4
        if(Op1[1]=='*'){
            if(Op2[0]=='*'){Position==3;}
            else{Position==2;}
        }
        else{Position=1;}
    }
}
