Consider the following three function definitions in Haskell: first x y = x ident x = x omega x = omega x We could also define these in ML, although with a slightly different syntax: fun Ident x = x; etc. How would the evaluations of the following expression in Haskell and ML compare= first (ident 3) (omega 1) (First (Ident 3) (Omega 1). in ML}

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)

C++ The function prototype of a function that recieves two integer values and computes their sum and difference is given as follows: void computeSum (int num1, int num2, int & sum, int & diff); write the statments to call this function to compute and print the sum and the differnce of 167 and 84.
