HEY ! ! ! ! I said that it can't run. Just tell me what's wrong with my interpreter:

#include <iostream>
#include <fstream>
#include <windows.h>
using namespace std;
int tape[65535];

int main()
{
	ifstream fin;
    fin.open("subleq.txt", ios::in);
    if (!fin.is_open())
    {
    	cout << "Failed to open SUBLEQ.TXT" << endl;
		return -1;
    }
	cout << "Program:\n";
	int cnt = 0;
	int n;
	char ch = ',';
	do
	{
		fin >> n >> ch;
		tape[cnt] = n;
		cnt++;
		cout << n << " ";
	}
	while(ch != ';');
	cout << "\n";
	fin.close();
	system("pause");
	int pc = 0;
	cout << "\n-----------\n";
	do
	{
		int a = tape[pc];
		int b = tape[pc+1];
		int c = tape[pc + 2];
		int na,nb,nres;
		if(a == -1){cin >> ch; na = ch;} else na = tape[a];
		if(b == -1){nb = 0;} else nb = tape[b];
		nres = na - nb;
		if(b == -1){cout << (char)nres;} else tape[b] = nres;
		if(nres <= 0) pc = c;
		else pc += 3;
	}
	while(pc >= 0);
	cout << "\n-----------\nThe Subleq program halts.";
	while(true) cout;
}

while the file subleq.txt contains:

18,-1,3,33,0,6,34,0,9,32,0,-1,32,0,15,34,34,0,72,101,108,108,111,44,32,119,111,114,108,100,33,10,32,-1,0;

I'll try to. I don't program in windows or C++. I am a little familiar with it though. I appreciate you sharing your code. I'll share mine with you once I get it reading files. Superstitionfreeblog (talk) 15:31, 16 October 2024 (UTC)

Sorry.I misunderstood "subtract a from b" as "a-b", and that is the problem. After all I think "negated"subleq is easier to use, but i don't know why. islptng 08:33, 4 November 2024 (UTC)
