The document discusses various control flow statements in C programming including switch case statement, break statement, and goto statement. It provides the syntax and meaning of switch case statement which allows executing different code blocks based on the value of an expression. It also explains the break statement which terminates the execution of a switch case or loop statement. The goto statement allows transferring program control unconditionally to another label in the program.

2. Multiple Selection:
The switch Statement
value1
action 1
value2
action 2
value3
action 3
value4
action 4
multiway
expression

3. Multiple Selection:
The switch Statement
Syntax:
switch (<selector expression>) {
case <label1> : <sequence of statements>;
break;
case <label2> : <sequence of statements>;
break;
case <labeln> : <sequence of statements>;
break;
default : <sequence of statements>;
}

4. Multiple Selection:
The switch Statement
Meaning:
 Evaluate selector expression.
 The selector expression can only be: a bool, an
integer, an enum constant, or a char.
 Match case label.
 Execute sequence of statements of matching label.
 If break encountered,
go to end of the switch statement.
 Otherwise continue execution.

5. switch ( day )
{
case0:printf(“Sunday”);
break;
case1:printf(“nMonday”);
break;
case2:printf(“nTuesday”);
break;
case3:printf(“nWednesday”);
break;
case4:printf(“nThursday”);
break;
case5:printf(“nFriday”);
break;
case6:printf(“nSaturday”);
break;
default:printf(“nError -- invalid day.”);
break;
Is this structure more
efficient than the
equivalent nested if-else
structure?

6. The break statement
 Syntax:
Effect:
break;
• When the break statement is executed inside a loop-
statement, the loop-statement is terminated immediately
• The execution of the program will continue with the
statement following the loop-statement

7. The break statement (cont.)
 Schematically:

8.  Syntax:
The go to statement
Sample: …………..; //label
……………….;
If()
{
………………;
break;
}
else
goto sample; //goto statement

9. Go to Example
 #include<stdio.h>
main()
{
aa:goto cc;
hum:printf(“the limit”);
goto end;
switch Example”);
goto dd;
cc:printf(“n n The”);
goto bb;
dd:printf(“tis”);
goto hum;
end:printf(“for the programmer”);
