1. A prime number is an integer greater than one and divisible only by itself and one.

The first seven prime numbers are 2, 3, 5, 7, 11, 13, and 17. Write a program that displays all the

prime numbers between 1 and 100

2. Write another program that accepts a number from the user and returns th Fibonacci value of that

number. You should use recursion in here.

3. Write a program that accepts a number and determine whether the number is prime or not.

4. Write a C++ code that computes the sum of the following series.

Sum = 1! + 2! + 3! + 4! + …n!

The program should accept the number from the user.

5. Write a C++ code to display only even numbers found between 222 and 180.

6. Write and run a program that reads a positive integer n and then prints a diamond of numbers Use for loop.  

Given an array A (8,8). Find the sum and the number of positive elements, located below the main diagonal the smallest element of the array (minimum).

1. Input five integers in one line, with each integer separated by a space.
2. Add the 1st and 2nd integers together and store the sum inside a variable.
3. Add the 3rd and 4th integers together and store the sum inside a variable.
4. Multiply the two sums and raise the product result to the power of the 5th integer.
5. Print out the result.

Input

A line containing five integers separated by a space.

1·2·3·4·5

Output

A line containing an integer.

1. Input three decimal numbers in one line separated by spaces, and make sure to store them in different variables.
2. Multiply the 1st and 2nd decimal numbers, and store the product into a variable.
3. Then, divide the product of the 1st and 2nd decimal numbers with the 3rd decimal number, then print out its quotient, with 2 decimal places.

Input

A line containing three decimal numbers with two decimal places separated by a space.

1.53·2.25·1.23

Output

A line containing the result with two decimal places.

1. Input two integers (one per line) and make sure to store them in variables.
2. Add the two integers and print out their sum!

• A) Create a function called To_Celsius that takes in a temperature in Fahrenheit temperature and returns the equivalent in Celsius.
• B) Create another function called To_Fahrenheit that takes in a temperature in Celsius and returns the equivalent in Fahrenheit.
• C) Use these functions to write a function called Print_EQ_Temps that prints out the Fahrenheit equivalents of all Celsius temperatures from 0°-100°, and the Celsius equivalents of all Fahrenheit temperatures from 32°-212°. Then, call this function in your program.

Hint: Use for loops to input into your functions.

Given an equation x1 + x2 + · · · + xn = k, where k is a

constant, and x1, x2, . . . ,xn are nonnegative integers (which are considered

as variables in the equation), list all the solutions. Write a C

or C++ program to solve this problem. The input is a pair of integers

(n, k) with k 

Define and initialize five arrays of integer types each having 6 elements and an array of pointers p of size 5. Store the starting address of each array to an array of pointers p. Design and call the function and initialize the values of these five arrays randomly using for loop and p inside this function. we can consider p as a 2D matrix. However, in that case, our number of rows (Which were 5 as there were 5 arrays stored in p) and the number of columns (which were 6 as each array had 6 elements) were fixed. In this question, your goal is to sort all data in the 2d array.
