Problem With Vc++

[iccaros]

ok I ran into a problem moving a program over to Vc++ to make sure it ran before sending in for home work.

the line

cout << s << flush;

from my function

int promptUser (const string& s)

{

while (true) {

int user_input;

cout << s << flush;

cin >> user_input;

if (cin.fail()) {

cerr << "invalid input \n";

cin.clear();

cin.ignore();

}

else

return user_input;

}

}

throws an error.

I had to change it to

cout << s.cstr();

to make it work..

any guesses on this one?

thanks..

I was banging my head aginst the wall as VC++ does not tell you where the error occured.. I think they want you to guess??

at least with Dev-c++ ane Gcc it says

array.cpp:34

where 34 is the line number

[jcl]

Huh. It builds and runs fine with both gcc -std=c++98 -pedantic and icc -strict_ansi. It should be fine unless both compilers are broken.

I'll add this to the list of things to check in the standard.

Edit: Does it work if you change that line to

cout << s;
cout.flush();

?

Vc++ (visual C++)

still throws an error..

Gcc never had a problem wiht it.. or the Borland or Intel Compiler..

It's only Vc++

[jcl]

Not sure what could be wrong. You might try to produce a minimal test case. Slice code out of the program until it starts working or you've reduced it to a single expression.

Edit: Just to be clear, is it a compile-time or run-time error?
