Explicit operators

[Seron]

Hello,

I get this error when I try to compile the code below. Why won't the Borland 5.5 compiler accept the and, or keywords?

Error E2293 Boolean3.cpp 17: ) expected in function main()

// Boolean3.cpp

#include <iostream>
using namespace std;

int main() {
double i,j;
cout << &quot;Enter a value (float): &quot;;
cin >> i;
cout << &quot;Enter another value (float): &quot;;
cin >> j;
cout << &quot;i > j is &quot; << (i > j) << endl;
cout << &quot;i < j is &quot; << (i < j) << endl;
cout << &quot;i >= j is &quot; << (i >= j) << endl;
cout << &quot;i <= j is &quot; << (i <= j) << endl;
cout << &quot;i == j is &quot; << (i == j) << endl;
cout << &quot;i not_eq j is &quot; << (i not_eq j) << endl;
cout << &quot;i and j is &quot; << (i and j) << endl;

}

Not equal to !=
AND &
OR |

also AND if(( yaba )&&( dabado ))
OR if(( yaba)||( dabado ))

In C++, not_eq is !=, and is &&, and or is ||. Also you need to put

return 0;

just before the closing bracket. You defined main to return an integer (which is the correct way of defining main()) so you need to return an integer. James P. Cottingham

Thanks for the replies.

I've read that the keywords and, or can be used instead of &&, || if the complier complies with Standard C++. Does Borland 5.5 compiler comply to C++ standard? Is it good or bad practise to use one or the other?
