### Cmis 102 Hands On Lab Week 8

##### Question

CMIS 102 Hands-On Lab

Week 8

Overview

This hands-on lab allows you to follow and experiment with the critical
steps of developing a program including the program description,
analysis, test plan, and implementation with C code. The example
provided uses sequential, repetition, selection statements, functions,
strings and arrays.

Program Description

This program will input and store meteorological data into an array. The
program will prompt the user to enter the average monthly rainfall for a
specific region and then use a loop to cycle through the array and
print out each value. The program should store up 5 years of
meteorological data. Data is collected once per month. The program
should provide the option to the user of not entering any data.

Analysis

I will use sequential, selection, and repetition programming statements and an array to store data.
I will define a 2-D array of Float number: Raindata[][] to store the
Float values input by the user. To store up to 5 years of monthly data,
the array size should be at least 5*12 = 60 elements. In a 2D array this
will be RainData[5][12]. We can use #defines to set the number of years
and months to eliminate hard-coding values.
A float number (rain) will also be needed to input the individual rain data.

A nested for loop can be used to iterate through the array to enter
Raindata. A nested for loop can also be used to print the data in the
array.

A array of strings can be used to store year and month names. This will allow a tabular display with labels for the printout.

Functions
will be used to separate functionality into smaller work units.
Functions for displaying the data and inputting the data will be used.

A selection statement will be used to determine if data should be entered.

Test Plan

To verify this program is working properly the input values could be used for testing:

Please try the Precipitation program again.

C Code

The following is the C Code that will compile in execute in the online compilers.

//  C code
//  This program will input and store meteorological data into an array.

//  Developer: Faculty CMIS102
//  Date: Jan 31, XXXX

#define NUMMONTHS 12 #define NUMYEARS 5 #include <stdio.h>

//  function prototypes void inputdata();

void printdata();

//  Global variables

//  These are available to all functions float Raindata[NUMYEARS][NUMMONTHS];

char years[NUMYEARS][5] = {"2011","2012","2013","2014","2015"}; char months[NUMMONTHS][12]

={"Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec"}; int main ()

{
char enterData = 'y';

printf("Do you want to input Precipatation data? (y for yes)\n"); scanf("%c",&enterData);

if (enterData == 'y') {

// Call Function to Input data inputdata();

// Call Function to display data printdata();

}
else {
printf("No data was input at this time\n");

}

printf("Please try the Precipitation program again. \n"); return 0;
}

// function to inputdata void inputdata() {

/* variable definition: */ float Rain=1.0;
// Input Data
for (int year=0;year < NUMYEARS; year++) {

for  (int month=0; month< NUMMONTHS; month++) { printf("Enter rain for %d, %d:\n", year+1, month+1); scanf("%f",&Rain);
Raindata[year][month]=Rain;

3

}
}

}

//  Function to printdata void printdata(){

//  Print data
printf ("year\t month\t rain\n");

for (int year=0;year < NUMYEARS; year++) {
for (int month=0; month< NUMMONTHS; month++) {

printf("%s\t %s\t %5.2f\n", years[year],months[month],Raindata[year][month]);
}

}
}

Setting up the code and the input parameters in ideone.com:

You can change these values to any valid integer values to match your test cases.

Results from running the programming at ideone.com

Learning Exercises for you to complete

1.       Modify the program to add a function to sum the rainfall for each year.
(Hint: you need to sum for each year. You can do this using a looping
structure). Support your experimentation with screen captures of
executing the new code.

2.       Enhance the program to
allow the user to enter another meteorological element such as windspeed
(e.g. 2.4 mph). Note, the user should be able to enter both rainfall
with screen captures of executing the new code.

3.       Prepare a new test table with at least 2 distinct test cases listing
input and expected output for the code you created after step 2.

4.       What happens if you change the NUMMONTHS and NUMYEARS definitions to
other values? Be sure to use both lower
experimentation with screen captures of executing the new
code
