Compileing ERROR

Does any one know why this is not compiling?


#include <cstdlib>
#include <iostream>
#include <ctime>
using namespace std;
int main()
{

int withinXpercent(double ref,double data,double x);
double ref;
double data;
double x = .05;

cout<<"Enter the boiling point of the substance: "<<endl;

cout<<"% if",&data;

if (withinXpercent(100,data,x))
cout<<"Your substance is Water."<<endl;

else if ( withinXpercent(357,data,x))
cout<<"Your substance is Mercury."<<endl;

else if ( withinXpercent(1187,data,x))
cout<<"Your substance is Copper."<<endl;

else if ( withinXpercent(2193,data,x))
cout<<"Your substance is Silver."<<endl;

else if ( withinXpercent(2660,data,x))
cout<<"Your substance is Gold."<<endl;

else
cout<<"Substance Unknown."<<endl;

return 0;
}
int withinXpercent(double ref,double data,double x)
{
if (( ref - x * ref) <= data <= (ref + x * ref))
return 1;
else
return 0;

}
Found a problem, your cout<<"% if",&data; is not the C++ format. That is C. You want the cin>>&data; function.

Also, unless you put a cin.get() at the end, your console window will close down without giving you time to read your final output.

Hope this helps.

Wow that help, it now compiles thanks, but it disappears after typing the boiling point. That is,I think there should be something that makes the program stay open to show the results. Do you know what that is?

a number of things. starting from worst to best...

system("pause") //on windows only
int c = getchar()
cin.get();
cin>> variable
getline(stream, std::string)
noecho(); getch() //linux only unless you have cygwin on windows
system("pause") //on windows only
int c = getchar()
cin.get();
cin>> variable
