Labeled Statements
case label
EXAMPLE 2
int i ;
void main (void) {
/* ... */
i=2;
switch(i) {
case 1:
i=i+4;
case 2:
i=i+3;
case 3:
i=i+2;
}
/* ... */
}
EXPLANATION
In example 2, the processing starts in the second case statement since i is 2. The third statement is also
consecutively performed since the case statement does not include a break statement. Thus, if the constant
expression and the control expression in the case statement match, the programs thereafter are performed
sequentially. A break statement is used to exit the switch statement.
