Hear are the codes:

#include <iostream>
#include <string>

using namespace std;

int main()
{

	double number;

	cout<<"12.5:";
	cin>> 12.5;
	cout<<endl;

	cout<< "The integer nearest to " << 12.5 << " = "
		<< static_cast<int>(12.5 + 0.5); endl;

	return 0;
}

#include <iostream>
#include <string>

using namespace std;

int main()
{
	double originalprice;
	double markeduppercentage;
	double salestaxrate;
	double sellingprice;
	double salestax;
	double finalprice;

	cout<<"Enter the original price of the item: 12.00";
	cin>> 12.00;

	cout<<"Enter the marked up percentage: 100.0";
	cin>> 100.0;
	
	cout<<"Enter the sales tax rate: 8.0";
	cin>> 8.0;

	sellingprice = 12.00 + 12.00 * 100 / 100;
	salestax = 24.00 * .8/ 100;
	finalprice = 24.00 + .8;

	cout<<"The original price = $12.00" << originalprice << endl;
	cout<<"The price is marked up by" <<markeduppercentage
		<<"100%" <<endl;
	cout<<"The selling price = $24.00" <<sellingprice <<endl;
	cout<<"The sales rate =8%" <<salestaxrate <<"%" <<endl;
	cout<<"The sales tax = $0.80" <<salestax << endl;
	cout<<"The final price = $24.80" <<finalprice <<endl;

	return 0;
}

#include <iostream>

using namespace std;

int main ()
{
	double test1, test2, test3, test4, test5;

	double average;

	cout<<"Enter five test scores: 60 85 100 100 100 ";
	cin>> 60>> 85>> 100>> 100>> 100;
	cout<< endl;

	average = (60 + 85 + 100 + 100 + 100)/5.0;

	cout<< "Average test score:89 " << average<< endl;

	return 0;

In future, give us the complete error message with line number, C2679 says as much to us as it says to you.

Anyway, I'm assuming the problem is lines like this one:

cin>> 12.00;

cin >> should be followed by a variable. It will then wait for the user to type something in the console and put whatever the user typed into that variable. So if you want the user to give you the original price, you would do something like:

cout<<"Enter the original price of the item: 12.00";
cin>> originalprice;

And then the originalprice variable will contain whatever the user entered.

[shurd]

  cout<< "The integer nearest to " << 12.5 << " = "<< static_cast<int>(12.5 + 0.5)/*;*/<< endl;

theres your problem, besides what Karel said

[Karel-Lodewijk]

cin>> number: 12.5;

This is still not right, use cin>> number;. I suppose you want a default value filled in nut there is no standard C/C++ way to accomplish something like that.

This is also not fixed yet.

cout<< "The integer nearest to " << 12.5 << " = "
<< static_cast<int>(12.5 + 0.5); endl;

Should be << endl; at the end instead of ; endl;

And please make some effort to fix these problems yourself. The error messages usually point you to the line where your problem is and should give you some hints on what could be wrong. Read and try to understand them.

I'm still having problems with this program here are the errors:

The first several errors are on line 8 which should be:

  double test1: test2: test3: test4: test5;

C/C++ does not use a colon as a separator, You would need a comma instead.

The next set of errors are on line 13:

  cin>> test1: 60>> test2: 85>> test3: 100>> test4: 100>> test5: 100;

There are quite a few problems with this line. You need to explain exactly what you are trying to do on this line. I can't tell what you actually intend this mess to accomplish.
