[SOLVED] Lab 1 Course: CSE 165

All the exercises below are selected from the textbook: Thinking in C++ (volume 1).

1. [Exercise-2 on Page 120] Using Stream2.cpp and Numconv.cpp as guidelines, create a program that asks for the  radius of a circle and prints the area of that circle. You can just use the ‘*’ operator to square the radius. Do not try  to print out the value as octal or hex (these only work with integral types). [25 points]

2. [Exercise-1 on Page 226] Create a header file (with an extension of ‘.h’). In this file, declare a group of functions  by varying the argument lists and return values from among the following: void, char, int, and float. Now create  a .cpp file that includes your header file and creates definitions for all of these functions. Each definition should  simply print out the function name, argument list, and return type so you know it’s been called. Create a second .cpp  file that includes your header file and defines int main( ), containing calls to all of your functions. Compile and run  your program. [35 points]

3. [Exercise-3 on Page 227] Write a program that uses a while loop to read words from standard input (cin) into a  string. This is an “infinite” while loop, which you break out of (and exit the program) using a break statement. For  each word that is read, evaluate it by first using a sequence of if statements to “map” an integral value to the word,  and then use a switch statement that uses that integral value as its selector (this sequence of events is not meant to  be  good  programming  style;  it’s  just  supposed  to  give  you  exercise  with  control  flow).  Inside  each  case, print  something meaningful. You must decide what the “interesting” words are and what the meaning is. You must also  decide  what  word  will signal the  end  of  the  program.  Test  the  program  by  redirecting  a  file  into  the  program’s  standard input (if you want to save typing, this file can be your program’s source file). [40 points]

Requirements:

* Usage of spaces, blank lines, indention, and comments for readability

* Descriptive names of variables, functions, structs, classes, and objects (if any)

* Appropriate usage of structs, classes, and objects (if any)

Penalties:

* Zero if you have possession of a copy of online solutions or work done by someone else.

* 5-point deduction per day late
