Thanks for your explanation. Yeah I can see how you'd need to state the types again for the possibility that you'd be overloading functions. Otherwise it wouldn't know which function definition went with which prototype. I really appreciate the help guys. ...

Is that for Class/Object function prototype, I must define the function in header file or .cpp file. MyClass::functionA(); MyClass::functionB(); but for C function prototype, I don't have to define if it's put before the main() function the following i
A Function Prototype consists of the name of the function, and a list of its inputs and outputs. For mega- and macrofunctions, the Function Prototype can also contain parameters that are used to specify the characteristics of the function. Function Prototypes are specified in the Function ...
since a function identifier evaluates to a pointer expression. To use a function identifier in this way, the function must be declared or defined before the identifier is used; otherwise, the identifier is not recognized. In this case, a prototype forworkis given at the beginning of themainfu...

The meaning of TRIGONOMETRIC FUNCTION is a function (such as the sine, cosine, tangent, cotangent, secant, or cosecant) of an arc or angle most simply expressed in terms of the ratios of pairs of sides of a right-angled triangle —called also circular fu
In this case, a prototype for work is given at the beginning of the main function.The parameter function in work is declared to be a pointer to a function taking one int argument and returning a long value. The parentheses around the parameter name are required; without them, the ...
