Can you please write these in language C for someone with beginner knowledge $($first grader at college$)$ to understand, thank you.

Exercise: Functions Using Math Library

Write a C function which gets base of double type and exponent of integer type as parameters and returns baseexponent

Write a main function to test the above function.

Example: Implement Password Control

First ask the user to specify a $5-$digit password. Read and store the user input in a variable named password. Print out that password has successfully been stored.

Next, write a loop that prompts the user to enter their password, which warns the user after $3$ wrong attempts. Steps are:

If the user types in the correct password, print out "Login Successfull".

As long as the user types in the wrong password, prompt the user again. After the third wrong attempt, print "Your account has been locked." and terminate your program.

Two Examples with User Input

Sum of First $n$ Numbers

Write a program that prints the sum of the first $n($user$-$input value$)$ integers

Calculating Averages

Write a program that takes $n$ numbers iteratively from the user, in each iteration computing and printing the average of the numbers till that time.
