As a constant?
#include <iostream>
int main()
{
double value = 1.23456E+3;
std::cout << "value = " << value << '\n';
return 0;
}
/* my output
value = 1234.56
*/

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

You aren't supposed to unless you have a perverse fascination with ancient dialects of C.

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).
