Write a program that outputs "Hello!" exactly 7 times. Your code must consist only of the main () function, and the body of the program must consist entirely of calls to Fork () and/or conditional statements (possibly nested) of the form "if (Fork()==0)" or "if (Fork()!=0)”, and exactly one printf("hello\n"); statement, followed by exit(). Recall that Fork() calls fork () and returns if and only if that call succeeds. Draw a process graph for your program. Label the nodes corresponding to printf calls.

Variables and Constant

Constants and variables are widely used in mathematical equations and expressions. They are also commonly found in the domain of programming, where each language has its own way to differentiate between a constant and a variable. Since they have all sorts of applications, knowing their differences is a good place to start.

Question

**Exercise: Process Creation and Graph Representation**

**a. Program Task**

Write a program that outputs "Hello!" exactly 7 times. Your program should only include the `main()` function. The program body must solely consist of calls to `Fork()` and/or conditional statements (possibly nested) in the form of `if (Fork() == 0)` or `if (Fork() != 0)`. Include exactly one `printf("Hello\n");` statement, followed by `exit()`. Remember, `Fork()` calls `fork()` and returns only if that call succeeds.

**b. Process Graph**

Draw a process graph for your program. Label the nodes that correspond to `printf` calls.

In C++ A system is set up to take raw grading information from the console and calculate a consolidated grade. The information comes in as a single line with first name, last name, homework grade (a tota out of 20), lab grade (a total out of 50), exam grade average, and a letter (upper or lower) indicating Audit, Passfail, or Grade. Sample: Mary Poppins 17 28 87 g A program should be written that takes the input data and calculates a consolidated FINAL grade based upon 10% Homework, 20% Lab, and 70% Exams.

Design a function called intdiv() which takes a dividend and a divisor as parameters and returns the result and remainder (2 integers) as a tuple. E.G. given 9/2 equals 4 remainder 1:9 is the dividend, 2 is the divisor (parameters), 4 is the result and 1 is the remainder (values returned as a tuple).Write program statements which test this function by calling it twice with different parameters, and printing the returned values each time.
