Write a function called set_plan(), which accepts, a string for a plan name, an integer for goal calories, and a pointer to an Excersie_plan. The function indirectly sets (via the pointer to the Excersie_plan) each component in the struct to the values passed into the function. The function does not return a value.
PHP Write a reduce function Write a function reduce($arr, $func) that takes an array and a function as a parameter. The reduce function should apply the parameter function to each element of the array in succession to produce a single result. Note: the current result should always be the first parameter to the function and the next element of the array should always be the second parameter. You may not use the PHP function array_reduce in your solution. For example, the result of the following should be 10. function myMax($current, $new) { return $current < $new ? $new : $current; } $arr = array(10, 5, 3, 5, 1, 2, 5, 7, 4); print("Max: " . reduce($arr, 'myMax') .
Q3 OCaml type signature 1 Point The OCaml type signature val f : 'a -> a = indicates that function f has a parameter and return value that can be any type, as long as the types of f 's parameter and return value are the same.

Programming in C CorrectFormation Create a program and locally declare in main fname and Iname and completeName. Ask the user for their first and last name. Put the values into fname and Iname. You will create a function that is called as followed. joinNames( fname, Iname, completeName ); You will pass the first name array, the last name array, and the array that will contain the complete name. The function named joinNames should put the first and last names together in completeName. Make sure that the first and last names begin with capital letters, and that all others are lower case. Display the final combined name.

Given a structure for student as follows: struct student { int ID; float grade; } s[5]; Use scanf to have user enter ID and grades for each student: 1st student ID =1, Grade = 90 2nd student ID=2, Grade = 81.5 3rd student ID=3, Grade = 85.5 4th student ID=4, Grade = 88 5th student ID=5, Grade = 94 Each student as a structure needs to have the ID and grade properly set. Output: The average grade for 5 students' needs to be reported using printf. Also, each student ID and Grade need to be reported. NOTE: Use structure syntax as needed. Use for loop when you deal with arrays.
Consider the following structure: struct student { int id; char name[50]; float cgpa; }list[10]; a) Write a function that finds the average cgpa. The function should display the student ids, names and cgpas of the students holding the cgpa less than the average cgpa. b) Write a function to display all the student names with their cgpa

Description Write a short program that will define a function called make_book that will have 3 parameters: ● book_title book_author] book_length with a default value of 100 It will return a dictionary with the keys 'title', 'author', and 'length'. You will then call this function 2 times (not in a loop): • The first time specifying all parameters by order: Ulysses by James Joyce with 762 pages • The second time specifying the title and author by keyword: The Odyssey by Homer And print the dictionary returned by the function in a simple print statement. Specification • You should submit a single file called MidtermExam3.py • It should follow the submission standards outlined above. The assignment name will be Midterm Exam 3 • Each print statement should be sent a single f-string as an argument or nothing at all. For example: o Don't do this: [print("My variable is ", myvar1) o This is ok: print (f"My variable is {myvar1}")) o This is ok: print()
