1 Program A computer program (also software, or just a program) is a sequence of instructions written in a sequence to perform a specified task with a computer. 1

2 Creating a C++ Program created using an IDE source code Object code Executable code: exe file An Introduction to Programming with C++, Fifth Edition 2

3 Processing a C++ Program (cont'd.) C++ Programming: From Problem Analysis to Program Design, Fifth Edition 3

4 The Problem Analysis Coding Execution Cycle (cont d.) C++ Programming: From Problem Analysis to Program Design, Fifth Edition 4

5 Structure of C++ Program To include header files in our program Header File Contains built-in-functions. These are also called pre-defined or already developed functions Preprocessor Directives Angle or pointed brackets Return type of main function. It is used to determines whether the program is executed successfully or not. Void means nothing Body Begin 1 2 #include<iostream.h> #include<conio.h> void main( ) { Function Name main function Parenthesis shows function. It is used to pass parameters/arguments h stands for header file File name(standard input output ) Starting point of program execution 3 Program Body Body End Cout stands for console output.. It uses insertion operator (<<) print the output on the monitor/console. } cout<< Welcome to Computer Scientists ; getch(); Each statement must end with semicolon. A statement without Get character String or message to be semicolon generates function. It get a displayed on monitor. It must be syntax error. character at runtime. enclosed in double quotes( ) But we use it to stay screen to see output 5

6 Standard input and output streams cin Key Board >> Standard input stream cout << Monitor << cerr Memory Standard output stream

7 Simple Steps to write and run a program in C Go to this path C:\TC\BIN then double click on short to open C++ language. 2. Now save your program by choosing a meaningful program file name. e.g. welcome.cpp is a file name for a program that will display welcome message at runtime. 3. Now write your program as explained in the previous slide. (translation of algorithm to a c++ program). 7

8 4. Press Alt+F9 key to compile program. If your program is error free then following screen will appear: 8

9 5. Now press Ctrl+F9 key to run the program. Following screen shows the output of the program: Now press enter to go back to the source code of the program 9

10 Another Sample Program Program: #include<stdio h> void main() { int number; cout<< Enter an integer: \n ); //message for user cin>>number; //get input cout<< The number you entered is: <<number; getch(); } Output: Enter an integer: 25 The number you entered is: 25 10

11 Programming Style C++ is a free-format language, which means that: Extra blanks (spaces) or tabs before or after identifiers/operators are ignored. Blank lines are ignored by the compiler just like comments. Code can be indented in any way. There can be more than one statement on a single line. A single statement can continue over several lines. In order to improve the readability of your program, use the following conventions: Start the program with a header that tells what the program does. Use meaningful variable names. Document each variable declaration with a comment telling what the variable is used for. Place each executable statement on a single line. A segment of code is a sequence of executable statements that belong together. Use blank lines to separate different segments of code. Document each segment of code with a comment telling what the segment does. 11

12 Variable: Location in memory where value can be stored An identifier is a name for a variable, constant, function, etc. Rules to Declare an Identifier (variable) Alphabets from A to Z or a to z The digits from 0 to 9 Underscore(_) can be used The first character of an identifier can not be a digit The name of an identifier can not be a reserve word No space allowed in the name of identifier Valid Name: A Student_Name _Fname Pi Inalid Name: $Sum //special ch. 6StName // 1 st letter digit F name // no space allowed int // reserve word 12

13 Identifier (variable) Declaration Syntax Data-Type Space Variable-Name(Indentifier); e.g. int frstnumber; char choice; float divide; long output; Identifier (variable) Initialization Syntax Data-Type Space Variable-Name(Indentifier) = Value; e.g. int frstnumber=10; char choice= y ; float divide=0.0; 13

14 Memory Concepts cin>> first; Identifier Variable Assume user entered 45 cin>>second; Assume user entered 72 first 45 first 45 second 72 sum = first + second; first 45 second 72 sum

15 Assignment Operator (=) = (assignment operator) Assigns value to variable Binary operator (two operands) Example: sum = variable1 + variable2; 15

16 How many bytes I am eating? integer data short int long 2 bytes 2 bytes(16 bit system) 4 bytes (32 bit system) 4 bytes Floating point data float double long double 4 bytes 8 bytes 10 bytes Character char 1 byte Boolean bool 1 byte 16

17 Memory Allocation for Arithmetic Data Types Size (bytes) Range of Values Name (alternate) Description AVR GCC MSVC++ AVR GCC MSVC++ char Character or small integer 1 1 short int (short) Short integer 2 2 int Integer 2 4 long int (long) Long integer 4 4 long long int (long long) Really long integer 8 8 float 'Single-precision' floating point number 4 4 double 'Double-precision' floating point number 4 8 Signed: -128 to 127 (-2 (8-1) to 2 (8-1) -1) Unsigned: 0 to 255 (0 to 2 8-1) Signed: to Unsigned: 0 to Signed: to Unsigned: 0 to Signed: -2,147,483,648 to 2,147,483,647 Unsigned: 0 to 4,294,967,295 Signed: -9.2E+18 to 9.2E+18 Unsigned: 0 to 1.8E+19 1E 38 (7 decimal digits of precision) 1E 38 (7 decimal digits of precision) Signed: -128 to 127 Unsigned: 0 to 255 Signed: -32,768 to 32,767 Unsigned: 0 to Signed: -2,147,483,648 to 2,147,483,647 Unsigned: 0 to 4,294,967,295 Signed: -2,147,483,648 to 2,147,483,647 Unsigned: 0 to 4,294,967,295 Signed: -9.2E+18 to 9.2E+18 Unsigned: 0 to 1.8E+19 1E 38 (7 decimal digits of precision) 1E 308 (15 decimal digits of precision) long double Long double-precision floating point number 8 1E 308 (15 decimal digits of precision) 17

18 18

19 Arithmetic Rules of operator precedence Operators in parentheses evaluated first Nested/embedded parentheses Operators in innermost pair first Multiplication, division, modulus applied next Operators applied from left to right Addition, subtraction applied last Operators applied from left to right 19

20 Comments Non - executable statements Comments are used for program documentation Two formats Single Line Comments Multi Lines Comments // This program is used to show the Welcome Message. /* This program is used to show the square of even numbers from 10 to 100. */ 20

21 Tokens Tokens are individual words and punctuation marks in passage of text. In C++, program the smallest individual units are known as C Tokens. C++ has Six types of Tokens. The Tokens are shown in figure. C++ programs are written using these tokens and the syntax of the language. 21

22 22

23 C++ keywords Each keyword has a predefined purpose in the language. Do not use keywords as variable and constant names!! Exmples: bool, break, case, char, const, continue, do, default, double, else, extern, false, float, for, if, int, long, namespace, return, short, static, struct, switch, typedef, true, unsigned, void, while etc.. etc 23

24 Thank You New Computer Scientists 24

25 Memory Concepts Variable names Correspond to actual locations in computer's memory Every variable has name, type, size and value When new value placed into variable, overwrites previous value 25
