Use C++ to complete the following problem

1.Write a program that prompts the user for three integers, calculates the minimum and prints it out to the console.

2.Write a loop that prints out every third number between 0 (included) and n (excluded) where n is an integer larger than 3 entered by a user.

Note: You don't need to write a main, only the loop is sufficient.

3.Implement a program that calculates the sum of all numbers from 1 to N where N > 1. For example: For 5 it would be 15: 5 + 4 + 3 + 2 + 1 = 15.

1. In the main function, the program prompts the user for an integer. Validate the input repeatedly until a valid value is entered.
2. The integer is passed as an argument to a function named sumUp
3. The function sumUp calculates the sum of 1 to N and returns the result. Define proper parameters and proper return type for the function.
4. In the main function, the program shows the result on the screen.

Note: The program does not need to output the equation!

Sample Run:

Input: 4

Sum: 10

4.Declare a string array of size 5. Use a loop to store five fruits in the array that are entered by the user. Then find the longest string in the array and output it.

Hint: Use .length() on a string variable to determine the number of chars in a string.

Sample Run: Fruit 1: banana Fruit 2: apple Fruit 3: lemon Fruit 4: pears Fruit 5: orange Longest: banana
