Control statement

This document discusses different types of control flow statements in C++ including selection statements like if/else and switch statements, iteration statements like for, while, and do-while loops, and jump statements. Selection statements allow a program to choose one of several paths to execute based on conditions, while iteration statements repeat parts of a program. Jump statements abruptly transfer control from one part of a program to another. The document provides examples of how each type of statement is structured in C++ code.

 Flow of control  Statement  Selection /decision  Iteration/loop  Jump statements 2
 The flow of control jumps from one part of the program to another, depending on calculations performed in the program  Program statements that cause such jumps are called control statements. There are two major categories: loops and decisions 3

 Statements are the instructions given to the computer to perform any kind of action , be it data movements, be it making decisions or be it repeating actions.  Statements are the smallest executing unit of a C++ program. 5
 A compound statement in C++ is a sequence of statements enclosed by a pair of branches { }. { statements 1 ; statements 2 ; : } represents a compound statement 6
 The selection construct means the execution of statements depending upon a condition evaluates true, a set of statements is followed. 7

 Also known as either or. This statement is used to select one statement and ignore the other statements. if(condition) s1; else s2; when the condition is true statement s1 is executed. If the condition is false s2 is executed. Thus one of the statements, either s1 or s2 is always executed 9
 It is a multi branch statement which can be used to select and execute one of the available statements. switch(value) { case 1: statement 1; break; case 2: statement 2; break; case n: statement n; break; default: statement d; } 10
 Loops cause a section of your program to be repeated a certain number of times.  When the condition becomes false, the loop ends and control passes to the statements following the loop 11
 for Natural "counting" loop  do-while Least flexible Always executes loop body at least on  while Most flexible No “restrictions 12
 It is a repeated structure which can repeat a statement as long as the given condition is satisfied. for(statement1; condition; statement2) statement3; 13
While loop while(condition) statement1; Do while loop do { statement1; } while(condition); 14
 The types of jump statement are: 1)Break 2)Continue 3)Goto 4)Exit 5)Return 15
