A school is developing a program to keep track of information about students and their class schedules. In which of the following instances would a data abstraction be most helpful? O a. A program includes repeated programming statements that could be moved inside a loop O b. The program includes individual variables to store the names of each student rather than a single list of students. O C. A program includes repeated code that could be moved inside a function. o d. A program includes multiple comments that could be combined into a single comment

Create a program in C as follows:- Declare four floats as a1, a2, a3 and a4- Create a menu as follows:Option T to ask the user for and assign values to each of a1, a2, a3, and a4.Option V to call a function named cat that has four pointers of type float as parametersand no return. The function will sort, in ascending order, the values in a1, a2, a3 and a4.Option B to call a function named mouse that has four pointers of type float asparameters and no return. The function will sort, in descending order, the values in a1,a2, a3 and a4.Option K to call a function named dog that has four floats as parameters and no return.This function will print to the screen each of the values in a1, a2, a3 and a4 in aformatted manner (right justified with a field width of 12).Ex:a1 = 23.65a2 = 99.22a3 = 1.56a4 = 0.50Option X to exit the program.
A variable defined inside a function has local significance only. A variable definedexternal to a function is global and may be read but not modified by a function, itshould be declared global in the function to be modified. Arguments passed to afunction may be in arbitrary order when the name of the parameter is specified uponcalling the function. These concepts are illustrate the code where thenumber of occurrences of a letter in a word is counted and returned along with anincremented value of an input variable.
Write a C++ program with two user defined functions. The first function named “functionWithArray” takes two user input arguments of character types and return True if first argument is smaller than the second argument (alphabetically) and returns False otherwise. Write the second function named “functionWithPointers” which behaves like the first functions but uses pointers to receive the arguments. You may assume that both character arrays contain only lower-case letters, and no blanks or other non- alphabetic characters. Write a suitable Main function to test these two functions
12. John is used to doing programming in Python and since the print() function in Python by default prints a newline after printing the string passed to the print() function. But in his current project, he is using PHP programming language and the echo function does not print a newline by default after the end of the string. So, he often misses giving a newline after printing a message. Help David by writing a function myecho() that takes a string as a parameter and also prints a newline after printing the string.
1 - Nuclear Power Plant (python) The nuclear powerplant at Threeyedfish will automatically run a program to print a warning message when the reactor core becomes unstable. The warning message reads: NUCLEAR CORE UNSTABLE!!! Quarantine is in effect. Surrounding hamlets will be evacuated. Anti-radiationsuits and iodine pills are mandatory. Since the message contains crucial information, it should be printed three times. To do this, write a function that prints this message. This function has to be used three times.

In C++build a program to read that data with the following promptsa-) Create a class “name” with two data members: one for the first name (String) and one for the surname (String). The last name must be a pointer to char, the first name construct it as you prefer.b-) Create a grade class to store a subject name (String) and a grade (floating).c-) Create a class "student" that inherits from the class "name" and by composition can store the student's grades (consider that the maximum possible grades will be 6).d-) Create a group class to store the data of several students (consider a maximum of 10 students)e-) Develop a method that returns the average of the group of students.f-) Develop a method that returns the average of a student given his name and surname.g-) Develop a method that returns a list of students who have failed a subject (less than 6.0 points) given the name of the subject.h-) Develop a method that returns the first and last name of the student with the lowest…
For C++, How would I call or use a function that is passed by pointer or a reference? How would I use these in this example below? I understand how passing by value works, but when it comes to passing by references and pointers, that is when I get confused. #include <iostream> using namespace std; // passing by reference in this function void pass_ref(int &ref); // passing by pointer in this function void pass_ptr(int* ptr);
PYTHON Call expressions, such as square(2), apply functions to arguments. When executing call expressions, we create a new frame in our diagram to keep track of local variables: Evaluate the operator, which should evaluate to a function. Evaluate the operands from left to right. Draw a new frame, labeling it with the following: A unique index (f1, f2, f3, ...) The intrinsic name of the function, which is the name of the function object itself.For example, if the function object is func square(x)[parent=Global], the intrinsic name is square. The parent frame ([parent=Global]) Bind the formal parameters to the argument values obtained in step 2 (e.g. bind x to 3). Evaluate the body of the function in this new frame until a return value is obtained. Write down the return value in the frame. If a function does not have a return value, it implicitly returns None. In that case, the “Return value" box should contain None. Let's put it all together! Draw an environment diagram for the…
Write C++ code for the following tasks: Write a prototype for the function named fsum() that accepts two parameters: an array A of integer pointers and a variable x of type double. The return type of this function is int. Store three integer values entered as command line arguments in an integer array A.  Insert the string “ Offline” after the first occurrence of character „o‟ in the string s1= “Hello World”. Also, print the ASCII value of each character in this modified string after insertion.  Define a function replace() that receives an integer number as parameter and replaces it with a number formed by rearranging the digits of the original number. The return type of the function is void.  Define a class A that declares a static variable count of type integer. Initialize the value of count to zero. Use the variable count to count the number of objects of the class A.
Give an example of how calling an inline function is different from calling a normal function in the background, and explain how the difference came to be. Also, give a specific example of how the change came about.
Concepts of programming language Consider the following JavaScript program: var a, y, c;function sub1() {var b, z, c;function sub2() {var a, b, y;. . .}. . .}function sub3() {var a, x, w;. . .}List all the variables, along with the program units where they are declared,that are visible in the bodies of sub2 when the sequence of function call is:“sub1 calls sub3 and sub3 calls sub2”, assuming dynamic scoping is used.
