2.  Flow of control
 Statement
 Selection /decision
 Iteration/loop
 Jump statements

3.  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

5.  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.

6.  A compound statement in C++ is a sequence
of statements enclosed by a pair of
branches { }.
{
statements 1 ;
statements 2 ;
: }
represents a compound statement

7.  The selection construct means the execution
of statements depending upon a condition
evaluates true, a set of statements is
followed.

9.  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

10.  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;
}

11.  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

12.  for
Natural "counting" loop
 do-while
Least flexible Always executes loop body
at least on
 while
Most flexible No “restrictions
12

13.  It is a repeated structure which can repeat a
statement as long as the given condition is
satisfied.
for(statement1; condition; statement2)
statement3;
13

14. While loop
while(condition)
statement1;
Do while loop
do
{
statement1;
}
while(condition);

15.  The types of jump statement are:
1)Break
2)Continue
3)Goto
4)Exit
5)Return
