Question
How Would i get this to run if i were to use only vector statements to keep track of the number of rolls? not as a function but as a vector just to keep track of the number of rolls
#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;
int main(){
int i = 0; // Loop counter iterates numRolls times
int numRolls = 0; // User defined number of rolls
int numTwos = 0;
int numThrees = 0;
int numFours = 0;
int numFives = 0;
int numSixes = 0; // Tracks number of 6s found
int numSevens = 0;
int numEights = 0;
int numNines = 0;
int numTens = 0;
int numElevens = 0;
int numTwelve = 0;//
int die1 = 0; // Dice values
int die2 = 0; // Dice values
int rollTotal = 0; // Sum of dice values
int idK = 0;
cout << "Enter number of rolls: " << endl;
cin >> numRolls;
srand(time(0));
while (numRolls >= 0){
if (numRolls >= 1) {
// Roll dice numRoll times
for (i = 0; i < numRolls; ++i) {
die1 = rand() % 6 + 1;
die2 = rand() % 6 + 1;
rollTotal = die1 + die2;
// Count number of sixs and sevens
if (rollTotal == 2){
numTwos = numTwos + 1;
}
else if (rollTotal == 3) {
numThrees = numThrees++;
}
else if (rollTotal == 4){
numFours = numFours++;
}
else if (rollTotal == 5){
numFives = numFives++;
}
else if (rollTotal == 6) {
numSixes = numSixes + 1;
}
else if (rollTotal == 7) {
numSevens = numSevens + 1;
}
else if (rollTotal == 8){
numEights = numEights++;
}
else if (rollTotal == 9){
numNines = numNines++;
}
else if (rollTotal == 10){
numTens = numTens++;
}
else if (rollTotal == 11){
numElevens = numElevens++;
}
else if (rollTotal == 12){
numTwelve = numTwelve++;
}
cout << endl << "Roll " << (i + 1) << " is "
<< rollTotal << " (" << die1
<< "+" << die2 << ")";
}
// Print statistics on dice rolls
cout << endl << endl;
cout << "Dice roll statistics:" << endl;
cout << "2s: " << numTwos << endl;
cout << "3s: " << numThrees << endl;
cout << "4s: " << numFours << endl;
cout << "5s: " << numFives << endl;
cout << "6s: " << numSixes << endl;
cout << "7s: " << numSevens << endl;
cout << "8s: " << numEights << endl;
cout << "9s: " << numNines << endl;
cout << "10s: " << numTens << endl;
cout << "11s: " << numElevens << endl;
cout << "12s: " << numTwelve << endl;
else {
cout << "Invalid rolls. Try again." << endl;
}
return 0;
}
Explanation / Answer
Here is the code to maintain the similar kind of output, but with vectors, which also reduces the lines of code.
