Class Assignment

Having trouble with this assignment not sure how to fix all 4 things. having difficulties with all of them. Please help.

cout<<"I have "<<"myMoney"<<" and you have "<<yourMoney<<endl;

First, please use code tags when posting code. See http://www.cplusplus.com/articles/jEywvCM9/

Second, are there 4 or 12 homework assignments?
(threads http://www.cplusplus.com/forum/beginner/232545/ and http://www.cplusplus.com/forum/beginner/232546/ )


What do you mean by "debugs" and "fix"?

Is the real nature of these homework that you have been given erroneous code and your task is to figure out what is not correct and propose changes?

Your compiler is your friend. If you try to compile a code that has syntactic errors, then the compiler will tell what it does not like. (Some compilers are more to the point than others, but all do say something.)


Lets take an example:

//DEBUG1-1
#include<iostream>
void main()
double myMoney, yourMoney;
myMoney = 286.72;
yourMoney = 124.67;
cout<<"I have "<<"myMoney"<<" and you have "<<yourMoney<<endl;
system(:pause:);

reports:

4:1: error: expected initializer before 'double'
5:1: error: 'myMoney' does not name a type
6:1: error: 'yourMoney' does not name a type
7:1: error: 'cout' does not name a type
8:7: error: expected constructor, destructor, or type conversion before '(' token

Start from first error, for the other errors might be only side-effects of the first:

4:1: error: expected initializer before 'double'

Line 4 is: double myMoney, yourMoney;

What is before 'double'?

#include<iostream>
void main()

Compare that to http://www.cplusplus.com/doc/tutorial/program_structure/

* What return type should the main() have? Are both void and int valid?
* What should be after the main()? A { ?

Hello Masonbrady3,

Since this is an assignment you should start by compiling each example and see what errors you get. Then when compiled run the program to see what output you get.

Just looking at the first example I see three possible errors/problems. One may not be an problem for you depending on how old your compiler is.

The use of "system" anything is not a good idea as it could leave your program open to attack. I look at this a forth problem.

I looks like the point is to find the mistakes. If I tell you all the answers you will miss the opportunity to learn how to debug a program, yours or someone else's.

Instead of asking for all the answers compile and then run the program(s) and figure out what is wrong.

Hope that helps,

Andy

just compile them

check does:
using namespaces std;
