Your software requires that user’s passwords meet the following criteria: The password should be at least sixteen (16) characters long. The password should contain at least: one uppercase letter one lowercase letter one digit one special character (no spaces) Write a program that asks for a password and then verifies that it meets the stated criteria. If it doesn’t, the program should display a message telling the user why. Whenever possible, use pointers. Manually destroy any memory used when finished using it.Write a C++ program that calculates the average of a group of test scores, where the lowest score in the group is dropped.

Implement a simple security software program using symmetric key cryptography Run the (same) program, twice, in this order (note the command line arguments below): programName 1 ‘messageToBeEncrypted’ keyFileName ciphertextFileName - 1 means encryption - compute symmetric key and write the key to file, keyFileName - messageToBeEncrypted’ stuff that needs to be encrypted - compute ciphertext and write ciphertext to file, ciphertextFileName programName 2 keyFileName ciphertextFileName - 2 means decryption - read the key from key file, keyFileName - decrypt content of file, ciphertextFileName, and cout the decrypted text to the terminalUse the C programming language. Do not use any other programming language like Python. Write one C file only for this problem. Only use variable declarations, assignments, operations, conditional constructs, and iterative constructs. Input should be taken in a value from the user (use scanf). Be sure to use loops to complete the solution. The use of functions is optional.
- (Conversion) a. Write a C++ program to convert meters to feet. The program should request the starting meter value, the number of conversions to be made, and the increment between metric values. The display should have appropriate headings and list the meters and the corresponding feet value. If the number of iterations is greater than 10, have your program substitute a default increment of 10. Use the relationship that 1 meter = 3.281 feet. b. Run the program written in Exercise 6a on a computer. Verify that your program begins at the correct starting meter value and contains the exact number of conversions specified in your input data. c. Modify the program written in Exercise 6a to request the starting meter value, the ending meter value, and the increment. Instead of the condition checking for a fixed count, the condition checks for the ending meter value. If the number of iterations is greater than 20, have your program substitute a default increment of (ending value - starting value) / 19.strictly use " operator overloading " WHILE SOLVING PROBLEM IF NOT FOLLOWED WILL BE GIVEN A DOWNVOTE.

The station has four pumps connectedto four tanks with capacities: 100, 75, 50, and 150. Every timea car fills up it takes 10 gallons. You’ll know that a car hasarrived because the carArrived function will return with apump number. After a car has filled up, print out the currentcontents of all four tanks.• Write a C program that can track each of the four tanks. Updatethe amount of gas remaining in a tank when a car fills up.When a tank gets to less than 20 gallons of gas remaining,make a call to request a refill truck visit the station(refillRequest). This will cause the tank to berefilled automatically
