Need help on Q1

Total is 20 this type of short question, This is just some of them due to can't put everything in. Can anyone help? Question 1 [20 marks] Note: For Question 1, you are not allowed to use any functions in the library. Each of the function below needs to be run in a program. Each of the programs should have at least one test case (with a screen capture) which shows the successful running of the program. a)Write a function checkeven that take in two parameters: an array call numarray containing integers and its size. The function should return the number of even integers in the array. You should initialise some values into the array numarray. b)Implement a function calculate to take in two integer parameters num1, num2 and a third parameter operator of character type and return the resulting operation. The function should use the 'switch ' keyword to determine the operation depending on the given operator. For example, if num1 = 2, num2 = 3 and operator = "+" then the returned result should be 5. The function should display an error message for invalid operator other than *,/,- and +. c)Implement an iterative function called xypower that take in 2 reference parameters x and y. Upon exit the function xypower stores the value of x to the power of y back to x and stores the value of y to x back y. For example, if x = 2 and y = 3, upon exit of xypower, x will have the value 8 (2 to power of 3) and y the value 9(3 to the power of 2). d)Write a function vowelcount that take in a string parameter and return the number of vowels ( a,e,i,o,u, A, E, I, O, U) in it. You are not allowed to use any C String Library functions. e)Write a function called ReturnSmallerChars that take in 2 five-character string parameters str1 and str2. The function compares each of the corresponding character in str1 and str2 and copies the smaller or same character (with the smaller or same ASCII code) into a temporary string and then returns it. For example ReturnSmallerChars ("ABC", "abc") returns "ABC" (as 'A' of str1 is smaller than 'a' of str2 in cell 0 and so on).
