The document provides instructions for an experiment on arrays in C programming. It includes 5 problem statements: 1) Modify a program to calculate the mean of elements stored in an array instead of variables, 2) Design a program to calculate the effective inductance of coils in serial or parallel using arrays to store inputs and outputs repeating 5 times. The report must include the source code, output, flowchart/pseudocode, testing and conclusion for each problem statement.

#5 Array
Case Study#1: The mean or average value is defined as the sum of all elements divided by
the number of elements. The equation for calculation of the mean value for n elements is as
follows.
n −1
∑m i
m0 + m1 + m2 + ... + mn−1
meanval = i =0
=
n n
Figure1 illustrates how the mean value for n elements is calculated using repetition
structure. The variable sum is first set to zero. A for loop is then used to read the value of
elements, and perform additional operations of all elements received by variable m. The
variable meanval contains the mean value.
Figure1 The PS_arrays.c containing a program to calculate the mean value for n elements
Problem Statement 1:In this experiment, modify the above source code by applying an
array. The modified program should receive the value of each element and stored in
array m. The modified program should perform the same operations; calculating and
displaying the mean value for n elements, and produces the same output as given
program in Figure1.
Execute the modified source code and report the findings.
Problem Statement 2:Design a program to calculate and display the effective inductance
(L) of two coils arranged in (i) serial OR (ii) parallel. The user should provide connection
of coils, inductance of L1, inductance of L2 and mutual inductance (M). This program
should repeat 5 times. Use array L1, L2, M and conn to save all the inputs and array L
to save all the outputs.
