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.

For this program implement the following methods before implementing the main method (which must make use of these methods):

static int getValidTemperature (int dayNum)

static int getWarmest(int temp1, int temp2)

static void readIntegers (int[] list)

static int getWarmestTemperature(int[] list)

static double getAvgTemperature(int[] list)

static int countWarmDays(int[] list)

static void displayList(int[] list)

write a program that contains two functions i.e., encrypt_string() and decrypt_string()a.encrypt_string(s): Thisfunction uses the following dictionary:encrypt={'a':'1','b':'@','c':'*','d':')','e':'$','f':'#'}This function should accept a string as its parameter and return anencrypted string. To encrypt a string, use the dictionary given above. Read each character of the string(match it with the keyin the dictionary)and replace each character with the given encrypted value(valuein the dictionary)and return the encrypted string.b.decrypt_string(s)This function uses the following dictionary:decrypt={'1':'a','@':'b','*':'c',')':'d','$':'e','#':'f'}This function should accept an encrypted string as its parameter and return the decrypted/original string. To decrypt a string, use the dictionary given above. Read each character of the string(match it with the key in the dictionary) andreplace each character with the given decrypted value(value in the dictionary)and return the decrypted string.

In traditional way, there are three classes: TRUCK (number, name , NoOfWheel, Price, Capacity, EnginePower, TypeOfConsump), BUS (number, name , NoOfWheel, Price, NoOfSeat, EnginePower, TypeOfConsump, Color, Speed), CAR (number, name , NoOfWheel, Price, NoOfSeat, EnginePower, TypeOfConsump, Color, Speed).

Divide the above three classes into two base classes and three derived classes. Each class will contain two member functions, getdata() to get that class data from user and putdata() to display that class data on the screen

Write a program to read numbers from a file.

C++ programming

Create a structure called Exam that includes exam ID (string), name of the subject (string), 

registration fee (double) and the number of students registered during a week (7 days) (int 

array). • Write a function called getExamDetails() which is the data type of Exam that reads the 

details of the Exam and store them in the variable of the Exam structure. 

Hint: Use the given function prototype as 

Exam getExamDetails (Exam e); 

• Write a function called calExamFee() which takes three parameters, registration fee for 

the exam, the number of students registered during a week (7 days) array and the size of the array. Find the total exam registration fee during the week and print the total exam 

registration to the screen. • Call the getExamDetails() and calExamFee() in the main function to print the following 

output as required.

In traditional way, there are three classes: TRUCK (number, name , NoOfWheel, Price, Capacity, EnginePower, TypeOfConsump), BUS (number, name , NoOfWheel, Price, NoOfSeat, EnginePower, TypeOfConsump, Color, Speed), CAR (number, name , NoOfWheel, Price, NoOfSeat, EnginePower, TypeOfConsump, Color, Speed). 

Divide the above three classes into two base classes and three derived classes. Each class will contain two member functions, getdata() to get that class data from user and putdata() to display that class data on the screen. How the above member data of three classes will be distributed into five classes as shown in the following diagram.

Compute and display the output of the Area (A) of a rectangle, the length (L) is 10 and the width (W) is 15. 

1) Write a program that declares a structure to store the record of a book. It defines a structure variable, input the values and displays them using pointer.

2) Write a program that input two integers and passes them to a function using pointers. The function exchange the values and the program finally display the values.
