CMIS 102 Hands-On Lab
// Week2
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, design, and implementation with C code.
Program Description:
This program will sum two integer numbers to yield a third integer number. It will also divide two float numbers to yield a third float number. Once the calculations are made the results of all the numbers will be printed to the output screen.
Analysis:
We will use sequential programming statements.
We will define 3 integer numbers: a,b,c. c will store the sum of a and b.
We will define 3 float numbers: f,g,h. h will store the quotient of f and g.
Test Plan:
To understand this program the following input numbers could be used for testing: a = 10 b = 20 c = a + b = 10 + 20 = 30 f = 75.0 g = 3.0 h = f/g = 75.0/3.0 = 25.0
Design using Pseudocode:
// This program will sum two integer numbers to yield a third integer number.
// It will also divide two float numbers to yield a third float number. // Declare variables
Declare a,b,c as Integer
Declare f as Float
// Set values of Integers
Set a=10
Set b=20
Set c=a+b
// Print c
Print a,b,c
Set f=75.0
Set g=3.0
Set h=f+g
// Print h print f,g,h

C Code
The following is the C Code that will compile in execute in the online compilers.
// C code
// This program will sum two integer numbers to yield a third integer number.
// It will also divide two float numbers to yield a third float number.
