How does a value-returning function differ from the void functions?
Step by step
Solved in 2 steps
- Why do you need to include function prototypes in a program that contains user-defined functions? (5)Mark the following statements as true or false: a. To use a predefined function in a program, you need to know only the name of the function and how to use it. (1) b. A value-returning function returns only one value. (2, 3) c. Parameters allow you to use different values each time the function is called. (2, 7, 9) d. When a return statement executes in a user-defined function, the function immediately exits. (3, 4) e. A value-returning function returns only integer values. (4) f. A variable name cannot be passed to a value parameter. (3, 6) g. If a C++ function does not use parameters, parentheses around the empty parameter list are still required. (2, 3, 6) h. In C + + , the names of the corresponding formal and actual parameters must be the same. (3, 4, 6) i. A function that changes the value of a reference parameter also changes the value of the actual parameter. (7) j. Whenever the value of a reference parameter changes, the value of the actual parameter changes. (7) k. In C++, function definitions can be nested; that is, the definition of one function can be enclosed in the body of another function. (9) l. Using global variables in a program is a better programming style than using local variables, because extra variables can be avoided. (10) m. In a program, global constants are as dangerous as global variables. (10) n. The memory for a static variable remains allocated between function calls. (11)In a void function, how would you utilise a return statement?
- Keyword _____________is used in a function header to indicate that a function does not return a value or to indicate that a function contains no parameters.When calling a function with several arguments, parameter order matters.Write a function that takes 3 parameters that are numbers. The function should return the sum of the numbers. Write function calls to test the function. Javascript
- You cannot have both keyword arguments and non-keyword arguments in a function call.Parameters are the value passed to a function when the function is called and Argument are the variable defined in the function definition. True or falseC++ Can a variable name be passed to a value parameter in C++ functions?
