What were you trying to do?
Compile a small c++ file to test stream manipulators
What's wrong:
The manipulators left, right, scientific, fixed, and internal do not seem to be defined in the g++ class iostream, where as they are in gcx. As a result, the file did not compile.
What should have happened:
The compiled program should have simply output some numbers, demostrating the effects of some of the above manipulators.
Please describe any relevant documentation references:
Here is the source file I was trying to compile with g++ (it worked fine with gcx):
#include <iostream>
#include <iomanip> // For setw() and setprecision()
using namespace std;
int main()
{
double x1 = 0.123456, x2 = 23.987, x3 = -123.456;
// a)
cout << left << setw(15) << x1 << endl;
// b)
cout << fixed << setprecision(2) << right << setw(12)
<< x2 << endl;
// c)
cout << scientific << setprecision(4) << x3 << endl;
// Output: -1.2346e+002
// A field width of 12 or more would be convenient!
return 0;
}
