Array Practice

/*
Write a C program that computes the sum of all the
values in an array. Assume that he values are
numbers.

Write a C program that computes the average of all
the values in an array. Assume that he values are all
integers.

Write a C program that finds the largest number in an
array. Assume that he values are all integers.

Write a C program that finds the smallest number in
an array. Assume that he values are all integers.

Write a C program that finds the second largest
number in an array. Assume that he values are all
integers.

Write a C program that increments each value in an
array. Assume that he values are numbers.
