As a constant?
#include <iostream>
int main()
{
double value = 1.23456E+3;
std::cout << "value = " << value << '\n';
return 0;
}
/* my output
value = 1234.56
*/ "One of the methods used by statists to destroy capitalism consists in establishing controls that tie a given industry hand and foot, making it unable to solve its problems, then declaring that freedom has failed and stronger controls are necessary." --Ayn Rand

And the line of code that goes with this error? Clearly you're trying to do something that looks something like a K&R style function definition, but C++ doesn't allow those.

um not sure what K&R is; have not learned that yet but the line where the error is the "{" right after main to start writing the code
>um not sure what K&R is
You aren't supposed to unless you have a perverse fascination with ancient dialects of C.
>the line where the error is the "{" right after main
That is soooooo incredibly NOT helpful. Not even I can debug a program given one character (most of the time
). How about posting that line as well as five lines above it (using code tags, because I'm not in the best of moods).
