- 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)(Numerical) Write a program that tests the effectiveness of the rand() library function. Start by initializing 10 counters to 0, and then generate a large number of pseudorandom integers between 0 and 9. Each time a 0 occurs, increment the variable you have designated as the zero counter; when a 1 occurs, increment the counter variable that’s keeping count of the 1s that occur; and so on. Finally, display the number of 0s, 1s, 2s, and so on that occurred and the percentage of the time they occurred.Write a isPalindrome Function Write a function isPalindrome($str) that returns true if the parameter string is a palindrome (a palindrome is a word or sentence that reads the same forward and backward at the character level). You should ignore non-letter characters when determining if the string is a palindrome. Thus, isPalindrome("A man, a plan, a canal, Panama!") should return true.
- Write and test a function that removes the leading and trailing spaces from a string. The function has two parameters. The first parameter is the address of the original string. The second parameter is the address of a string that is almost a copy of the original string. The difference between the strings is that the first string may have leading or trailing spaces and the second string will not have leading or trailing spaces. Use the function Str_length to compute the length of the original stringdef truth_value(integer): """Convert an integer into a truth value.""" # Convert 0 into False and all other integers, # including 1, into True if integer == 0: truth_value = False else: truth_value = True return truth_value Now, write a function that goes in the opposite direction of the truth_value() function. This new function should convert a truth value into an integer. In particular, True should be converted into 1 and False into 0. Name the new function integer_0_or_1(). All you need to include below is your definition of the function integer_0_or_1(). It will be tested automatically against relevant inputs. So include your function and nothing more.Write and test the “digit” function:Function Prototype: int digit(int n,int k)This function returns the kth digit of the positive integer n. For example, if n is the integer 29,415, then the call digit(n,0) would return the digit 2, and the call digit(n,2) would return the digit 4.
- Write a function which will take 2 arguments. They are: Sentence position Your first task is to take these arguments as user input and pass these values to the function parameters. Your second task is to implement the function and remove the characters at the index number which is divisible by the position (Avoid the index number 0 as it will always be divisible by the position, so no need to remove the index 0 character). Finally, add the removed characters at the end of the new string. Return the value and then finally, print the new string at the function call. ===================================================== Input:"I love programming."3Function call:function_name("I love programming.", 3)Output:I lveprgrmmngo oai. ============================================== Input:"Python is easy to learn.

(For the purposes of this exercise, we are talking about the standard 5 vowels -- A, E, I, O, U). Write a function that counts and returns the number of consonants in the string. Write a function that converts the string to all lowercase. Write a function that converts the string to all uppercase. Write the following functions. Each of these functions should have a single parameter -- accepting a c-style string as an argument. The function should only do what is specified (note that none of these functions do any output to the screen). Your functions should use const in the prototype wherever it is appropriate: Write the main function that offers a menu and allows the user to test the functions you have implemented. Program C++, must use c- style
- (Format an integer) Write a function with the following header to format the inte- ger with the specified width. def format(number, width): The function returns a string for the number with prefix 0s. The size of the string is the width. For example, format(34, 4) returns "0034" and format(34, 5) returns "00034". If the number is longer than the width, the function returns the string representation for the number. For example, format(34, 1) returns "34". Write a test program that prompts the user to enter a number and its width and dis- plays a string returned from invoking format(number, width). Here is a sample run:Playing with Functions: Write a Javascript program to check if the argument passed to any function is a function type or not. I.e. Create a function check which takes a argument and check if that argument is a function or not.Write a function argument_count that accepts an integer i, followed by any number of additional arguments. The function should returnTrue if the value given to i is equal to the number of arguments that follows it, and should return False otherwise.
