Structure problem.. stachdump

[austin7]

hi everyone, please help: I doing a structure problem, it compiles fine, it looks fine to me as well, gives me stackdumpfile error. Any suggestions folks.. please help:
Below is my code:
/*

*/
#include<iostream>
#include<iomanip>
#include<string>
#include<cstdlib>

using namespace std;

struct DrinkData {
string nam;
float pr;
int nB;
};

void getData(DrinkData[]);

int showChoices(DrinkData[]);

void processSelection(int, DrinkData[]);

float calculateEarnings(DrinkData[], int);

int main() {
DrinkData dd[5];
//getData(dd);
showChoices(dd);
do{
processSelection(showChoices(dd), dd);
}while(showChoices(dd)!=6);
cout<<"Amount earned : "<<calculateEarnings(dd,showChoices(dd));
}

void getData(DrinkData drink[5]) {
drink[0].nam = "Coke(Can)";
drink[1].nam = "Coke(Bottle)";
drink[2].nam = "Sprite(Bottle)";
drink[3].nam = "Water";
drink[4].nam = "Full Throttle";

drink[0].pr = 0.75;
drink[1].pr = 1.25;
drink[2].pr = 1.25;
drink[3].pr = 1.25;
drink[4].pr = 2.00;

drink[0].nB = 4;
drink[1].nB = 4;
drink[2].nB = 4;
drink[3].nB = 4;
drink[4].nB = 4;
}

int showChoices(DrinkData drink[5]) {
int ch;
cout << "Vending Machine Options :\n";
for (int i = 0; i < 6; i++) {
cout << "[" << i + 1 << "]" << " " << drink[i].nam << " ... " << "$"
<< drink[i].pr << "\n";
if (i == 5)
cout << "[" << i + 1 << "]" << "Quit the Program\n";
}

cout << "Enter your choice : ";
cin >> ch;

return ch;

}

void processSelection(int ch, DrinkData drink[5]) {

if (drink[ch].nB < 1)
cout << "The item is sold out.\n";
else {
drink[ch].nB = drink[ch].nB - 1;
cout << "The price is : " << drink[ch].pr;
}
return;
}

float calculateEarnings(DrinkData drink[5], int ch)
{
float amount= 0;
amount= amount+drink[ch].pr;
return amount;
}

wrap your code in code tags and format it properly

Thank Yanson, sorry about that as well, wasn't aware.

Line 63 for (int i = 0; i < 6; i++) { should be for (int i = 0; i < 5; i++) {

also you need to subtract one from ch in your processSelection function
the users options are 1 - 5 but the array is 0 - 4

Thanks Yanson got is sorted out:
