Hey guys,I'm having a go at re-writing a simple enough code I did, to use dynamic memory here is the header and the main Code: int assignOdds (int horse) ; // function to assign odds int whichHorseToBetOn (void) ; // function to ask which horse to bet on int getAmount (void) ; // function to ask how much to bet int runRace (void) ; // function to run the race Code: //Horse Betting #include <iostream> #include <ctime> #include <cstdlib> #include "betting.h" using namespace std ; int Cash = 100; // starting cash int const NUMBEROFHORSES = 8 ; int Bet = 0 ; // how much have they bet int horseWon = 0 ; int x =0 ; int odds[7] ; // array which holds each horses odds int tempOdds = 0 ; int winner = 0; int thisBet = 0; // holds horse bet on int Amount = 0; //. holds amount bet this race int main() { while (cash > 0) { cout << "You have " << cash << " to spend. \n" ; for(x=0 ; x<NUMBEROFHORSES ; x++) //loop asign and display odds { odds[x]= assignOdds(x) ; cout << "Horse " << x+1 << " Odds are " << odds[x] <<"/1 \n" ; } cout << "Which Horse do you want to bet on - " ; Bet = whichHorseToBetOn() ; thisBet=getAmount(); cout << endl ; winner=runRace();// selects winning horse randomly with runRace() function if (winner+1 == Bet) { cash = cash+(thisBet*odds[winner])+thisBet ; // If you have picked the winner then calculate earnings } } } int assignOdds (int horse) // assign random odds to horse { tempOdds=(rand()%10)+1; return tempOdds ; } int whichHorseToBetOn () { cin >> Bet ; return Bet ; } int getAmount () { cout << "How much do you want to bet? You currently have " << cash<< " to spend -\n "; cin >> Amount ; cash =cash -Amount ; return Amount ; } int runRace () // calculates randomnly which horse has won the race and displays it on screen { horseWon=(rand()%8); cout << "Horse " << horseWon+1 << " has won the race! " ; cout << endl << endl << endl ; return horseWon; } My question is if I were to replace the "Cash=100" keyword with int *ptr; ptr = new int; *ptr = 100; Would this work?
Please repost the code with line breaks; it's unreadable as just a single line. Also please use code blocks for all code. Regarding your question, I couldn't see "Cash=100" anywhere, but on the face of it (a) yes it should work; (b) why didn't you try it instead of asking here; (c) why would you want to do it this way anyway - what's the benefit of using a pointer?
