Answer:

The answer to this question is "The program will not compile."

Explanation:

In the given C++ programming language program. The program will not compile because in the program we define a class that is "TestClass" in this class we define a private variable and a function that is val and showVal(). In this function, we print the value of val variable. Then we define a parameterized constructor, in this constructor we use the private variable val that holds the constructor parameter value. Then we define a main function, in the main function we create a class object test which is defined wrong.

That's why the answer to this question is "The program will not compile."

Write the definition of a function typing_speed, that receives two parameters. The first is the number of words that a person ha
Lera25 [3.4K]

Answer:

The definition of function is as follows:

def typing_speed(number_of_words,Time_Interval):

number_of_words>=0  

Time_Interval>0

speed=float(60*number_of_words/Time_Interval)

return speed

Explanation:

Above function is defined step-by-step as follows:

        def typing_speed(number_of_words,Time_Interval):

  • A function named typing speed has two arguments, num_of_words and Time_Interval.

                             number_of_words>=0  

                             Time_Interval>0

  • The variable number_of_words is the number of words entered that a person enters, they must be greater than or equal to 0. Where as Time_Interval is the variable for counting the time span in seconds, it must be greater than 0.

                    speed=float(60*number_of_words/Time_Interval)

                    return speed

  • For determining result firstly the seconds are converted int minutes by multiplying with 60 and number_of_words is divided with Time_Interval in order to get words per minute. The return value will give speed which has data type float.

A programming language is not used to talk from human to human. It is used to talk from a human to a computer. Computers are very dumb compared to us, so they need to be taught or spoken to in simple terms. Asking them something complex is far beyond their understanding, as they cannot learn anything beyond what has already been taught to them. Using print: “Hello, World” is the way to tell them to do stuff way less complex than when we say ‘write the words Hello, World on the screen’. A programming language is also not very easy to create. Talking to a computer in a dumb way reduces the process to make a new language for the computer to understand.
