An identifier is the name of a program or the names of the variables, classes, methods, namespaces or interfaces within a program that are used to identify the relevant data/info.

Typically, identifiers must start with a letter (no numbers) and must not have any spaces in them, it should indicate the meaning and usage of the element being referred and i t cannot have more than 511 characters.

An example is:

int money;

Which of the following statements about global variables is true? 1.A global variable is accessible only to the main function. 2

Korvikt [17]

Answer:

A global variable can have the same name as a variable that is declared locally within the function.

Explanation:

In computer program, we refer to a global variable as that variable that comes with a global perspective and scope, ensuring its visibility throughout the program, except it is shadowed. The set of this kind of variable is referred to as global state or global environment. One feature of global environment is that it can have similar name as a variable declared locally within the function.

Write a recursive program that calculates the total tuition paid over certain number of years. The tuition goes up by 2.5% per y

Lisa [10]

Answer:

The program is as follows:

def calctuit(pay,n,yrs):

if n == 0:

return

pay*=(1.025)

print("Year ",yrs,": ",pay)

calctuit(pay,n-1,yrs+1)

n = int(input("Years: "))

pay = float(input("Tuition: "))

yrs = 1

calctuit(pay,n,yrs)

Explanation:

The function begins here

def calctuit(pay,n,yrs):

This represents the base case

if n == 0:

return

This calculates the tuition for each year

pay*=(1.025)

This prints the tuition

print("Year ",yrs,": ",pay)

This calls the function again (i.e. recursively)

calctuit(pay,n-1,yrs+1)

The function ends here

This gets the number of years

n = int(input("Years: "))

This gets the tuition

pay = float(input("Tuition: "))

This initializes the years to 1

yrs = 1

This calls the function

calctuit(pay,n,yrs)
