Well it says clearly what is the problem. You need to use the function strcpy there is nothing called strcopy in standard library – and the corresponding implicit declaration considered by compiler is invalid – it complained. Actually C99 doesn’t allow implicit declaration – it showed error that’s why. Other options is to declrare the … Read more
This code is valid. But to invoke it, you must execute java PrintMsg and not java PrintMsg.Main as it seems you’re doing. java expects the fully qualified name (package + class) of a class containing a main method. Your class name is PrintMsg.
You’re initializing the variable myChar as type char, but trying to fit a String inside. Java uses double quotes (“”) for Strings and single quotes (”) for chars. To fix this is simple: char myChar=”\u00A9″; The single quotes make ALL the difference!
Another homework question? Seems to be the season for them. Here’s a point in the right direction: getTwoRandomNumbers takes some parameters. Look at the function declaration, it’s asking for something. Other than that, listen to the first comment on your main question. I highly suggest doing some basic reading on C++. Update: People seem to … Read more
This is an error1: a++ += b because a++ returns a temporary (a pr-value) the language forbids you to modify since it is discarded as soon as the full expression has been evaluated. This is a kind of fail safe. My understanding of this had been that this expression would first evaluate a+b, store that … Read more
Change the code from })} // this line I get the error to this }}); You need 2 consecutive closing braces: the first to finish the handle method, the 2nd to finish the EventHandler the outer close parentheses is to finish the setOnAction call. And finally a semi colon to complete the statement.
Change this: if (y == 1) int gender = askGender(); To this: int gender; if (y == 1) gender = askGender(); Or even better this: int gender = 0; // default: 0 if (y == 1) gender = askGender();
Headers included with one compiler are typically tailored to that compiler implementation and will not necessarily work correctly with a different compiler. So generally speaking you won’t be able use the headers that come with Visual Studio with another compiler.
