Hey everyone,
Alright, my project requires that I write a program to demonstrate my understanding of class inheritance. Problem is the teacher wants us to use Java, something I have never used and...

Never mind, i got it.

Hi everyone,
I need to write a compiler using Yacc and I have encountered a problem. Since some of the code is C i thought I would try here. The problem occurs at one line in the following...

Hi everyone,
I need to write a compiler with Yacc that will basically perform minor algebraic commands. Here is the code so far for the Yacc part.


%token INTEGER VARIABLE READ WRITE
%left...

Are you expecting someone to write the code for ya?

Speak clean english and you might get a few more responses.

I had a feeling my grasp of declaring the arrays was the problem. Could anyone tell me why the seg fault occured though after the entire program ran instead of when it hit that bad code?

Don't know if there is a function built-in off the top of my head but it would be so easy to just write your own.

double max_find()
{
double max = 0; // This may need to be initalised...

I am writing a program that will build a graph and then find the lowest costs between any given vertices. I have the program building the graph just fine, but now I just started to write the part...

I need to set a variable to infinity or the highest possible number for the computer. But I have no idea how to do this. I did this a little while dabbling in assembly but I am unsure how to do...

Are you kidding me? The last person to try this at least offered to pay money. :rolleyes:

If you can't write it in english you won't be able to write it in c++.

A quote from my teacher, "the sooner you start to code, the longer the program will take to write".

Your function loan_schedule is written wrong. The function header requires parameters. While your function call and prototype have no parameters. I'm surprised it even compiles.

Future note...

I've never seen the time function but I would just guess it would have to look like this.

a=sqrt(x);
j=time(sqrt(x));

average=(.4f*midterm)+(.6f*final);

What are the f's for?

Where is the problem occuring? Have you done any debugging at all? Do your records that you attempt to sort even exist?

So you don't need to use cout << " "; as you originally stated?

Oh, how about

fin >> some_array[whatever_index];

I think you can fill in the right names.

Oh yeah, also your b and c variables are only initialized to work the first time through. After the first run b and c are equal to zero and therefore those two nested for loops will do nothing. I...

First thing I see on quick glance is you need an endline command at the end of the for loop.

No, variable names can be whatever you want. If you want to can choose to use only one letter variable names. Or you could have variable names that look similiar to previous post. Or you can use a...

Is it compiling? I am not 100% confident with c++ but I don't think what your doing is possible. Try something like this...

final_grade = (.4*midterm)+(.6*final);

Just curious, was that code segment from the book or did you just make it up without thinking about the logic? Just looks like a goofy piece of code.

I can't help you but I have a feeling for anybody to be able to help you, you are going to have post some more info. You are asking a pretty broad question right now.

Whats wrong here? Are you having a problem or do you expect someone to write the program for you?

^^
Exactly. You need to find where the seg fault is hitting. When I have that problem, I usually fill my program with stupid couts like "entering _____ function", "about to enter so and so loop",...

Have you read some of the shit Narue has had to answer? I think this thread was quite uncalled for. I personally have no problem with Narue and have received good help from him/her on a couple of...

cout<<"\naverage of these numbers: "<<ave<<endl;

You are not passing any of you parameters in ave. I am surpised it is compiling at all. Should look like ave(array, 10).

That was quick. Told ya there might be more efficient ways. :D

Ok, so the destructor would look something like this.


// Implementation File
#include <string.h>
#include <iostream>
#include "tree.h"
using namespace std;

Heres a quick algo I just threw together. There probably are more efficient ways but this gets the job done.


float min, max, temp, count;
count = 0;

cin >> max; // Read in first #
cin...

I didn' know you could resize an array. I thought thats what vectors were for.

Huh, I was under the impression that the destructor was basically a C++ function where ~(constructor) would automatically delete everything to do with the class. I didn't know I had to write that...

Hey everyone,
I just started writing this program when I hit a problem with the destructor. Me and my buddies in the lab could not figure out what is going on. The error said something about...

First, your surface equation is wrong. Surface area is simply lengh*width. I'm not even sure what that equation you are using will actually calculate.

The warning comes from cramming a double...

Just a handful of errors.

First it probably was not compiling because of this area

int hours, //#of hours
minutes, //# of minutes

should be

int hours, minutes;

Hey Everyone,
I need to write a program where the first half builds what is basically a file directroy tree. Files and their paths will come in from file in the form...

/program/file/whatever
...

First, are you familiar with a stack and its methods?

If you are the process is simple. Based on what you have said,

while(!eof(yourfile))
{
fin >> temp;
stack.push(temp);
}

Not a master of the language but the error might be that you are dividing by zero. Not sure how C++ handles that off the top of my head.

Boo and hiss. "Proud" Chippewa here. :-|
