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)
1) In mathematics, a factorial of a number is calculated by multiplying that number by all of the successive values less than it, stopping at 1. For example, factorial of 4 is written 4! and calculated as: 4! = 4 * 3 * 2 * 1 = 24 2) Write a program consisting of two functions (plus the main function). The first function should read in a number and then return this value back to the main function. This value should then be passed as a parameter (by value) into the second function which calculates and displays the factorial. Note: validate the input value (in the first function) to be greater than 1. 3) Improve your program from question 2, by changing the second function (that calculates the factorial) so that the result is returned to the main function instead of being printed where it is calculated. A new display function should be created and called from the main function that displays the calculated value. 4) Write a program that reads in two numbers and stores them into two…
*You need to have at least one user define function *Language: C programming Write a program to find whether a given number is a Palindrome number (number that is same when you read from forward or backward). You need to take a long integer number from user as input and verify whether it’s a number and positive or not. If the input is not valid (e.g., string or float) or positive, then notify the user and ask to input valid positive number again. If the number is valid then check whether it’s a palindrome number or not. [Hint: For splitting the digits from the given number, you need to use mod % and div / operators. E.g., 123/10 = 12 & 123%10 = 3] Input: Key in a number to check: -23 Output: The number -23 is not valid Key in a number to check: 123454321 The number 123454321 is a PALINDROME Do you want to continue (y/n)? y Key in a number to check: 456734 The number 456734 is NOT a PALINDROME Do you want to continue (y/n)? n Good bye!!
Language: Python A particular talent competition has 5 judges, each of whom awards as score between 0 and 10 to each performer. Fractional scores, such as 8.3, are allowed. A performer's final score is determined by dropping the highest and lowest score received, then averaging the 3 remaining scores. Write a program that uses these rules to calculate and display a contestant's score. It should include the following functions: -getJudgeData() should ask the use for a judge's score, store in a parameter variable, and validate it. This function should be called by main program once for each of the 5 judges. -calcScore(score1, score2, score3, score4, score5) should calculate and return the average of the 3 scores that remain after dropping the highest and lowest scores the performer received. This function should be called just once by main and should be passed the 5 scores. Two additional functions, described below, should be called by calcScore, which uses the returned information to…

integer) Write a function that computes the sum of the digits in an integer. Use the following function header:def sumDigits(n):For example, sumDigits(234) returns 9 (Hint: Use the % operator to extract digits, and the // operator to remove the extracted digit. For instance, toextract 4 from 234, use 234 % 10 To remove 4 from 234, use 234 // 10 (=23) Use a loop to repeatedly extract and remove the digits until all the digits are extracted.) Write a test program that prompts the user to enter an integer and displays the sum of all its digits.
