Thread: Message in Borland C++

Hi, I'm using Borland Turbo C++ 4.5. Hope you all can help me.

I received a compile error message saying that the array size is too large in function main(). Can anyone help me to solve this problem?

I'm using the array of object which contain about 80 objects. Is this too large? Please advise.

Code:

#include <iostream.h>
#include <fstream.h>
#include <string.h>
#include <stdlib.h>
#include <windows.h>
#include <conio.h>
#include <ctype.h>

#define tableSize 80
#define textSize 1000

class Secret
{
	int length;
	char actual;
	char cipher;
	char text[textSize];
	char temp[textSize];

public:
	Secret(){};
	Secret(char a, char c){actual=a; cipher=c;}
	~Secret(){}

	int menu();
	void encryptMSG(Secret s[]);
};


void Secret::encryptMSG(Secret s[])
{
	char filename[15], ans;
	float count=0, time=0.0;

	system("cls");

	//Prompt to enter message for encryption
	cout << "\n";
	cout << "\tEncrypt Message" << endl;;
	cout << "\t---------------" << endl;
	cout << "\n\tEnter Message:" << endl;
	cout << "\n\t";
	cin.ignore();
	cin.getline(text, textSize);
	
	length=strlen(text);

	//Encryption process start
	for (int x=0; x<length; x++)
	{
		for (int y=0; y<tableSize; y++)
		{
			if (text[x]==s[y].actual)
			{
				temp[x]=s[y].cipher;
				count++;
			}
		}
	}

	//Display encrypted message
	cout << "\n\n";
	cout << "\n\tEncrypted Message:" << endl;
	cout << "\n\t";

	for (int z=0; z<length; z++)
	{
		cout << temp[z];
	}

	time=count/10000;

	cout << "\n\n\n\n";
	cout << "\tTime used for encryption: " << time << " seconds" << endl << endl;

	cout << endl << endl;
	cout << "\tSave the encrypted message into a file? [Y/N] ";
	cin >> ans;

	//Save the encrypted message to a file
	if (ans=='Y'|| ans=='y')
	{
		cout << endl;
		cout << "\tEnter file name [end with .txt]: ";
		cin >> filename;

		ofstream ofile(filename);

		for (int z=0; z<length; z++)
		{
			ofile << temp[z];
		}
		ofile.close();
	}

	return choice;

It would seem to be specific to your set up, it compiles and runs fine with VC. No help to you of course, but at least you know it is not a coding error!
