In C, all names (including functions) must be declared with a type before they can be used. Knowing a name's type allows the compiler to ensure that operations upon the name are valid for its type, thus preventing many common bugs that might otherwise be missed, such as trying to assign a string to an integer.
What else can I help you with?
Can you compile program without header file?
Yes,we can compile our program without header file without any error,but we can not use any predefine functions like printf,scanf.
Does a function call come before main?
It does not have to. What is necessary, is that a function be declared before using it, so you either need function declaration separately from definition, or you need to arrange the declaration/definition in the right order, which usually places the main() function last.
Can you write any c prigramme in c language witthout any function?
No. At minimum, you need to provide a main() function.
What are the three required sets of statements for every function that a programmer writes in C plus plus?
There is no requirement for any statement in a C++ function, let alone three sets of statements. For instance, the following is a perfectly valid function: void foo(){} Clearly this does nothing as it has no statements in the function body, but it is nevertheless a valid function. Perhaps you mean something else by "statements". The only requirement of a function is that it have a return type, a valid name, an argument list and a function body. The return type may be void, of course, and the argument list may be empty, but it must include the ellipses. The function declaration need not include the function body, and the argument list need only specify the type of argument (the argument names are optional and need not match those declared in the actual definition). The function name and the arguments define the function signature (the prototype), thus the three required "components" of a function are the return type, the signature and the function body.
What does a hydroelectric power station need to function?
In order for a hydroelectic power station to function, the station will need a large supply of water. The station will also require large generators with turbines in order to create power from the pressure of the water.
A predefine formula that allows us to do complicated calculations easily is known as a?
function
How do you predefine your document setting?
Record actions and play it every time you want documents with settings you have specified during recording.
What does a computer need so that it will function?
computer need its main component c.p.u to function .
Why do you need a brain?
You need a brain to function.
Does a GFCI need a ground connection to function properly?
No, a GFCI does not need a ground connection to function properly.
Does a GFCI need to be grounded in order to function properly?
No, a GFCI does not need to be grounded in order to function properly.
Can you compile program without header file?
Yes,we can compile our program without header file without any error,but we can not use any predefine functions like printf,scanf.
When finding the derivative of a point on a piecewise function does every function in the piecewise function need to be continuous and approach the same limit?
All differentiable functions need be continuous at least.
What statement do you need to include in a value-returning function?
In a value-returning function, you need to include a "return" statement to specify the value that the function should return back to the caller.
How do you you rewrite a rule as a function?
You need to give an example of the rule and the function you want.
Can you have a function that is not a relation?
No, a function must be a relation although a relation need not be a functions.
Does the nucleolus need anything to function?
no
