Design a function : float average(int n); The function reads n different number from keyboard and returns average of odd number out of them . design main function also, that will call this function

*You need to use at least one user define function Write a program to find the first n numbers of the Fibonacci series. You have to take a positive number from input and show all the Fibonacci numbers belongs to that range. If the number is not valid then notify the user and ask to input positive number again. If valid, then print the series. Input: Key in a number: 10 Output: Fibonacci Series: 0 1 1 2 3 5 8 13 21 34 Do you want to continue (y/n)? n Good bye!! Language:(C programming)

Write a function argument_count that accepts an integer i, followed by any number of additional arguments. The function should returnTrue if the value given to i is equal to the number of arguments that follows it, and should return False otherwise.

2. Code the given function and test it inside the main function. int Length(char* str){ // return the length of string str //write your code here}

When a function accepts several arguments, how important is it what order they are sent in?
