C++ pointer runtime error - c++

Question

I made a program using structure and pointer. But for some reason it is not working properly. The main problem is that, for-loop would no go as it would. It would be helpful if you could solve this problem
#include <iostream>
#include <string>
#include <sstream>
using namespace std;
struct Book{
string name;
int release;
};
int main(){
//local variable
int i;
string release_dte;
int choice;
//interface
cout << "Welcome to Book Storage CPP" << endl;
cout << "How many entries would you like to make: ";
cin >> choice;
Book* Issue = new Book[choice];
//for handler
for (i = 0; i < choice; i++){
cout << "Book: ";
getline(cin, Issue[i].name);
cout << "Release Date: ";
getline(cin, release_dte);
Issue[i].release = atoi(release_dte.c_str());
}
cout << "These are your books" << endl;
for ( i = 0; i < choice; i++){
cout << "Book: " << Issue[i].name << " Release Date: " << Issue[i].release << endl;
}
system("pause");
return 0;
}

Answer 1

You're not checking if the input succeeded, nor are you clearing the new line left after the extraction into choice:
if ((std::cout << "Book: "),
std::getline(std::cin >> std::ws, Input[i].name) &&
(std::cout << "Release Date: "),
std::getline(std::cin >> std::ws, release_dte))
{
Input[i].release = std::stoi(release_dte);
}
You should also be using std::stoi for C++ strings as shown above.

Answer 2

I could not exactly infer what is the problem you are referring to. But my guess is getline() function inside the for loop is not working properly, I suggest the code before the for loop to be like the following\
cin.ignore (std::numeric_limits<std::streamsize>::max(), '\n');
for (i = 0; i < choice; i++){
cout << "Book: ";
getline(cin, Issue[i].name);
cout << "Release Date: ";
getline(cin, release_dte);
Issue[i].release = atoi(release_dte.c_str());
}
Your final code should be
#include <iostream>
#include <string>
#include <sstream>
using namespace std;
struct Book{
string name;
int release;
};
int main(){
//local variable
int i;
string release_dte;
int choice;
//interface
cout << "Welcome to Book Storage CPP" << endl;
cout << "How many entries would you like to make: ";
cin >> choice;
Book* Issue = new Book[choice];
cin.ignore (std::numeric_limits<std::streamsize>::max(), '\n');
//for handler
for (i = 0; i < choice; i++){
cout << "Book: ";
getline(cin, Issue[i].name);
cout << "Release Date: ";
getline(cin, release_dte);
Issue[i].release = atoi(release_dte.c_str());
}
cout << "These are your books" << endl;
for ( i = 0; i < choice; i++){
cout << "Book: " << Issue[i].name << " Release Date: " << Issue[i].release << endl;
}
system("pause");
return 0;
}
This will work as you intended
