- 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)arrow_forward2. What is the truth value of each of the following statements? 8 is even and 6 is odd If 8 is odd and 6 is even, then 8 < 6.arrow_forwardExercise: Write the following equation as a C++ expression and state the order of evaluation of the binary operators: .2 x² y -3 sin(x) %3D .3 tan xarrow_forward
- a) Given the following if-else statement. Convert this statement to a ternary operator. if ( x > 10 && y < 20) Z = a + b; else Z = a - b; b) The square of a number is given as N2. For example, if N = 5, the square is 5 × 5 = 25. Write a complete C program that computes the square of any given N and displays the answer as "The square of N is P'. (where N is the value entered by the user and F is the computed square value). Prompt the user to obtain the value of N. c) Write the appropriate C code to do the following; ) Declare X and Y as integers, and Z as double precision floating point mbers. i) Read the values of X and Y from the keyboard. iii) Divide X with Y and assign it to z iv) Print the value of Z to the screen with 3 decimal places. v) Using a single statement, print the value of Z to the nearest integer.arrow_forwardWrite the negation of each statementarrow_forwardIn C Declare a variable of type double.- Ask the user for a value and place it in the declared variable.- Write code to check for and output statement stating whether the variable is zero, positive, ornegative.- Declare a variable of type character.- Ask the user for a letter and place it in the declared variable.- Write code to check for and output statement stating whether the variable is an upper caseletter, lower case letter, or not a letter (neither of the above).- Write a simple program that is a four function calculator that displays a menu with options a to add, s to subtract, m to multiply, and d to divide two numbers. Ask the user for two float variables in each operation and output the result.arrow_forward
- 6. B) Write equivalent expressions for each of the following by using De Morgan’s Law. !(a || b) !(y > 2 && !found )arrow_forwardWrite C assignment statements for the following: a. Assign a value of 0 to a variable called between if n is less than -k or greater than +k; otherwise, assign 1. b. Assign a value of 1 to a variable called divisor if digit is a divisor of num; otherwise, assign a value of 0. c. Assign a value of 1 to a variable called lowercase if ch is a lowercase letter; otherwise, assign a value of 0.arrow_forwardcan obtain the remainder of this division by using the % operator. For example, 10 % 3 is 1. In C++, the % can be applied only to integer operands; it cannot be applied to floating-point types. The following program demonstrates the modulus operator:arrow_forward

Convert the two expressions below to one assignment expression and run it. x=y+5;t=x*z-1;arrow_forward(b) Which of the following statements are true? In each case you should justify your argument informally. X + X * 2 i. {x > Y} {x - Y > 0} Y +Y div 2 ii. {x is even} X + x+1 X + 2 * X {x is odd} X + 2 * Y iii. {x = Y} {x = Y} Y + 2 * Xarrow_forward
