Make a c++ program that will input two numbers and display the sum of numbers. Do this five times. Use function for the computation of the sum.

2. Assume that you are given a dictionary called softball_scoresthat holds player names as key and their scores for a season as the corresponding value.

a. Write Python code that finds and displays the lowest score in the dictionary.

b. Display the name of the player who has the lowest score.

// Ex . 8.13 : ex08_13.cpp

// What does this program do ? 

#include < iostream > 

using namespace std ; 

void mystery1 ( char *, const char * ) ; // prototype 

int main ( ) 

{ 

  char string1 [ 80 ] ; 

  char string2 [ 80 ] ; 

  cout << " Enter two strings : "; 

  cin >> string1 >> string2 ; 

  mystery1 ( string1, string2 ) ; 

  cout << string1 << endl ; 

} // end main 

  // What does this function do ? 

void mystery1 ( char * s1 , const char * s2 ) 

{ 

  while ( * s1 ! = '\0' ) 

    ++ s1 ; 

  for ( ; ( * s1 = * s2 ) ; ++ s1 , ++ s2 ) 

    ; / / empty statement 

} // end function mystery1

Create C# programs for singleton design pattern using following implementations

1- Thread-Safety Singleton using Double-Check Locking.

2- Thread-safe without a lock.

3- Using .NET 4's Lazy<T> type.

1.    Perform the task in each of the following statements:

a) Write the function header for function zero that takes a long integer built-in array parameter bigIntegers and does not return a value.

b) Write the function prototype for the function in part (a).

c) Write the function header for function add1AndSum that takes an integer built-in array parameter oneTooSmall and returns an integer.

d) Write the function prototype for the function described in part (c).

Using Visual Studio, create a Console App that:

a. Has a class to encapsulate the following data about a bird:

1.

. English name

i. Latin name

ii. Date last sighted

a. Allows the user to enter the information for a bird;

b. Stores the information in a Bird object; and

c. Displays the information to the user.

Write a program that allows the user to enter any number of names. Your prompt can inform the user to input their first name followed by a space and last name. Order the names in ascending order and display the results with the last name listed first, followed by a comma and then the first name. If a middle initial is entered, it should follow the first name. Your solution should also take into consideration that some users may only enter their last name (one name).

Write an application that displays revenue generated for exercise classes at the Tappan Gym. The gym offers two types of exercise classes, zumba and spinning, six days per week, four times per day. Zumba is offered at 1, 3, 5, and 7 p.m.; spinning is offered at 2, 4, 6, and 8 p.m. When attendees sign up, they agree to pay $4.00 per class for zumba and $5.00 for spinning. Produce a table displaying the number of attendees per time slot. Display a row and column of totals showing the total number of attendees by day and also time period. Also include a column showing the revenue generated each day and the overall revenue per type of exercise. Do a compile-time initialization of your data structures using data from the following table.

Write a program that reads in 10 midday temperatures for Port Elizabeth, for 10 consecutive days.

Only temperatures higher than 0 and less than 45 are valid (working with integer values for

temperatures). It must calculate and display the following:

• The warmest temperature

• The average temperature

• The number of days that the temperature was higher than 30

• The list of temperatures entered

Using the following formula a = p ( 1 + r ) n .write a program that calculates and prints the amount of money in the account at the end of each year for 10 years. the program should use interest rate of 5%, 6%, 7%, 8%, 9%, 10%.
