Explanation / Answer

DEAR FRIEND i solved the error the index of the array was exceeding the allocated memory and this will get he program into a memory may have some system commands which cuased the error PLEASE RATE #include #include #include #include using namespace std; // Global const int ARRAY_SIZE = 15; // Struct struct ProductInfo { int number; // Product number string description; // Product Description double price; // Product Price }; // Function Prototype void showMenu(); void clearScreen(); void pauseScreen(); void openProductFile(ifstream &productFile); void readProductFile(ifstream& productFile, string & productCode, string & productDesc, double & productPrice, ProductInfo products[]); void bubbleSort(ProductInfo products[], int size); int binarySearch(ProductInfo products[], int size, long prodNum); /****************************************************************** Function: Main ******************************************************************/ int main() { // Set Variables int choice; ifstream prodFile; string product_code, product_desc; double product_price; ProductInfo products[15]; // numeric formatting cout
