int main(void) {
int input = -1;
double average = 0.0;
/* Use this for your input */
scanf("%d", &input);
/* This is the only output you need */
printf("%.1lf", average);
return 0;
}
Please write a C coding program (make it simple coding) that find the average of sequence integer. when user enter integers, once at a time. Also, If the user enters 0 (zero), the code will calculates the average and then prints it, and then exits.

PQ1. How would you declare the following scalar and non-scalar (vector) variables?
PQ2.
PQ3.
PQ4. The algorithm for checking if a number is a prime is to check if it is divisible by any number less than itself other than 1. (Divisibility implies that if you use the modulus operator, %, the result will be 0). Write a function to check if a number is a prime.

1. Create a base class called Vehicle that has the manufacturer’s name (type String), number of cylinders in the engine (type int). Then create a class called Truck that is derived from Vehicle and has additional properties: the load capacity in tons (type double) and towing capacity in tons (type double).
Add the following methods to the Vehicle class:
Add the following methods to the Truck class:
Write a driver program that tests all your methods. Create at least two objects of truck class, and two objects of vehicle class.

Need this in C#
Write a simple lottery program which can do the following:
1. asks the user to provide an integer value from 1 to 5
2. generates one random integer number from 1 to 5
3. display “You lost $1” if the two numbers are different, and display “You won $5” otherwise.the program asks if the user wants to continue playing the lottery.
If yes, the program repeats steps 1-3. If no, the program terminates.

Consider the following code:
values = [2, 5, 8, 12, 15]
values2 = {v % 3 for v in values}
What will be the length of values2?
Consider the following code:
values = ["moose", "giraffe", "antelope", "tortoise", "chinchilla"] values2 = [len(s) for s in values if "a" in s]
What will be the value of values2[1]?
Consider the following code:
numbers = [1, 2, 7, 9, 13] numbers2 = [n // 2 for n in numbers]
What will be the value of numbers2[2]?
