rps prob

[Bumpehh]

this is a very simple RPS game and i ran into a prob. heres the code

#include <iostream>  // for cout/cin
#include <cstdlib>   // for rand/srand
#include <ctime>    // for time
#include <cctype>   // for case conversion
using namespace std;
char rps;
char ai;
char redo = 'Y';    // all the variables
unsigned int num;
int win = 0;
int lose = 0;

void Convert(){  // func to check if input is lower and to conv to upper
cin>>rps;
if(islower(rps)) rps=toupper(rps);
}
void Random(){  // for random ai num
srand(time(0));
num = rand()%2;
}
void AiConvert(){   // conv random ai num to letter
switch(num){
case 0:
ai = 'R';
break;
case 1:
ai = 'P';
break;
case 2:
ai = 'S';
break;
default: ai = 'P';
}

}
void Compare();   // compare func

void Display(){  // func to display winnings and losses
cout<<"Total winnings: "<<win<<endl;
cout<<"Total loses: "<<lose<<endl;
}

int main(){   // main func
    cout<<"Welcome to my RPS!\nCall which option you want by initial!\n";
do{  // main loop
Convert();
Random();
AiConvert();
cout<<"AI picked: "<<ai<<endl;
Compare();
Display();
cout<<"Wanna try again? (Y/N)"<<endl;
cin>>redo;                             // see if still wanna play
if(islower(redo)) redo=toupper(redo);

}while(redo!='N');

}

void Compare(){     // compare func coding
if(rps=='R'||ai=='P'){
    cout<<"You lose!"<<endl;
    lose++;
}
if(rps=='R'||ai=='S'){
cout<<"You win!"<<endl;
win++;
}
if(rps=='P'||ai=='S'){
cout<<"You lose!"<<endl;
lose++;
}
if(rps=='P'||ai=='R'){
cout<<"You win!"<<endl;
win++;
}
if(rps=='S'||ai=='R'){
cout<<"You lose!"<<endl;
lose++;
}
if(rps=='S'||ai=='P'){
cout<<"You lose!"<<endl;
win++;
}
if (rps==ai){
cout<<"Tieee!"<<endl;
}

}

when i run it the ai runs like 3 time but only asks for my input once.
and im just lost. all help appreciated

You'be been told before about formatting your code properly.

[np complete]

Perhaps there remain something in your input buffer. You need to flush your input properly. There is an excellent article on flushing in Daniweb's C++ forum. Read that.

Last time you told me sloppy coding isnt serious lol.

and i dont understand when i would flush my input?

It means that somehow the program is receiving input for 3 times, using only onetime user input.
That means, there are some characters that remian in buffer after you have entered the first input. That's why I said to flush the input stream, that is stdin stream.

That's not at all what I said. I said "Don't apologize for sloppy coding. It only takes a minute or two to fix formatting." That means make it unsloppy so you don't have to apologize. And so we can read and follow it.

and i dont understand when i would flush my input?

Any time you do an input and don't read everything from the stream. Such as typing in "N[enter]" and reading a single character ('N') and leaving the '[enter]' in the stream for the next input.
