Answer:

The answer is "Option d".

Explanation:

In the given C++ program code, two-variable is defined, that is "s and i", in which variable s is a string type that holds a value, that is "abcde", and variable i is an integer type, that holds a value '1'.

  • In the next line, a while loop is declared, that uses integer variable which value is less than 5, inside a loop a substring function is used, that specifies the number of character and return its value.  
  • In array and string indexing starts from 0, and that variable i starts from 1, that is used in substring function, that's why it will print only "bcde".

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.
