I have a question for the following program:
#include <iostream>
#include <stdlib.h>
using namespace std;
int rolldice(){
int r1, r2, s = 0;
r1 = rand() % 6 + 1;
cout << "After rolling: " << r1 << endl;
r2 = rand() % 6 + 1;
cout << "After rolling: " << r2 << endl;
s = r1 + r2;
if(r1 == r2){
r1 = rand() % 6 + 1;
cout << "After rolling: " << r1 << endl;
r2 = rand() % 6 + 1;
cout << "After rolling: " << r2 << endl;
s += r1 + r2;
if(r1 == r2)
s = 1;
}
return s;
}

}
}
return j;
}
int findlast(int pos[]){
int i, j = 0, m = pos[0];
for(i = 1; i < 4; i++){
if(m > pos[i]){
m = pos[i];
j = i;
}
}

}
void calposition(int pos[], int sum[]){
int i, p, temp, j;
for(i = 0; i < 4; i++){
if(sum[i] == 1 || sum[i] == 12)
pos[i] = 0;

pos[i] = pos[p];
pos[p] = temp;
}
}
else{
if((pos[i] + sum[i]) <= 50)
pos[i] += sum[i];
}

}
cout << "|" << endl;
}
}
int findwinner(int pos[]){
int i;
for(i = 0; i < 4; i++){
if(pos[i] == 50){
break;
}
}
if(i == 4)
return 0;
else
return (i + 1);
}
int main() {
int pos[4];
int sum[4];
int i, temp, winner;
char choice = 'y';
cout << "Lets play, sorry!" << endl;
while(choice == 'y' || choice == 'Y'){
pos[0] = pos[1] = pos[2] = pos[3] = 0;
while(true){
for(i = 0; i < 4; i++){
cout << "Player " << i + 1 << " is rollong." << endl;
sum[i] = rolldice();
}
calposition(pos, sum);
display(pos);
winner = findwinner(pos);
if(winner > 0){
cout << "Player " << winner << " is winner!!" << endl;
break;
}
}
cout << "Wanna play again? (Y/N)" << endl;
cin >> choice;
}
return 0;
}
How did it display the player's position after every roll?
