C++ executes blanks after class creation - c++

Question

I'm trying to learn C++ to help my sibling with their assignment. So I'm attempting the assignment. It's a simple program to load a dictionary test file with words, their type, and definition to an array of Word type objects. I was able to get started with a normal string array instead of an object array as requested. But as soon as I defined the Word class and the array the code builds without an issue. When I try to run the code the cursor simply blinks for a few seconds and returns to the normal terminal.
Am I doing something wrong with my Class constructor ??
#include <fstream>
#include <string>
using namespace std;
class Word {
public:
string WordEntry;
string Type;
string Definition;
//constructor
Word(string word, string type, string definition){
WordEntry=word;
Type=type;
Definition=definition;
}
};
int main(){
cout << "Test1";
Word *wordArray[318555];
int count=0;
string word, type, definition,blank;
cout << "TEST" << count << "\n";
ifstream file("dictionary2021 (1).txt");
if (file.is_open()){
cout << "File dictionary2021.txt has been opened \n";
while (!file.eof()){
getline(file,word);
getline(file,type);
getline(file,definition);
getline(file,blank);
wordArray[count]= new Word(word,type,definition);
count++;
}
file.close();
cout << "File dictionary2021.txt has " << count/3 << " entries\n";
}
cout << "TEST" << count << endl;
cout << cc;
int selection;
string input;
cout << "Function List - Please hit Enter after your selection \n";
cout << " 1. Word Search \n 2. Repetitive z search \n 3. Wild Card Search\n";
cout << "Selection:";
cin >> selection;
if(selection=1){
cout << "Enter word:\n";
cin >> input;
string str("a");
for (int i = 0; i < 12; i+3)
{
cout << "1";
if (input.compare(str)== 0)
{
cout << wordArray[i+1];
return 0;
}
cout << "2";
}
}
}```

Answer 1

Word* wordArray[318555]; is a huge value and we're talking about 2548440 bytes (or roughly 2.4MB). This might be too large for a single stack frame and can easily be inefficient.
What I suggest is to use std::vector to store the word array and use std::vector<>::push_back() method to insert data to it.
Note: In your code snippet your not deallocating the Word object pointers once everything is done. Either explicitly delete those pointers using delete or use a smart pointer like std::unique_ptr.
