First Practice Program need help...C++

[Jeff.Brown]

Need help with simple code for calculating interest...not compound....yet. Can not figure out what code is needed to change the -double percent- to a -decimal-.

Giving me the error:

------ Build started: Project: Practice_Work, Configuration: Debug Win32 ------
Practice_Work.cpp
Practice_Work.cpp(24): error C2440: '=' : cannot convert from 'System:decimal' to 'double'
No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

Here is the Code i have written so far:

// Practice_Work.cpp : main project file.
// calculating intrest over one fixed period

#using <mscorlib.dll>
#include <iostream>
using namespace System;
using namespace std;


int main()
{

//declaring variables

double number= 0.0;
double percent= 0.0;
double difference= 0.0;
double sum= 0.0;

//Algorithms: assigning integers to variables

Console::WriteLine("Enter Amount: ");
number= Convert::ToDouble(Console::ReadLine());
Console::WriteLine("Enter Intrest Rate: ");
percent= Convert::ToDouble(Console::ReadLine());
percent= Convert::ToDecimal(percent);


//Calculations for solving the algorithm

difference= number*percent;
sum= number + difference;

//Printing out the results

Console::WriteLine("Total amount after interest equals: ",Convert::ToString(sum));


cin.get();

return 0;

}

[Alex F]

percent= Convert::ToDouble(Console::ReadLine());
percent= Convert::ToDecimal(percent);

Why do you need both lines? Use only one of them:

double percent= 0.0;
percent= Convert::ToDouble(Console::ReadLine());

If you want to use ToDecimal, declare percent as decimal.

Actually i figured it out, it was a simple issue with the math. Thank you for your help though, i ended up looking into that. funny how a break from constantly staring at code can produce simple answers lol

If you are compiling in the IDE, if you double click on the error in the errors window, it will take you right to the offending line of code.

After a short time, you'll pretty much know what the errors mean and how to fix them. Before then, just copy the error text into a bing or google search for additional hints on how to solve them.
