To take one of a number of possible actions.
switch is preferred over multiple if...else statements.
The general form of a switch statement is
switch(switch_expr)
{
case constant expr1 : S1;
S2;
break;
case constant expr1 : S3;
S4;
break;
.....
default : S5;
S6;
break;
}
The clause 'default' is optional.
#include
main(){
int i,n = 5;
for(i = 1; i switch(i%2)
{
case 0 : printf("the number %d is even \n",i);
break;
case 1 : printf("the number %d is odd \n",i);
break;
}
}
}
the number 1 is odd
the number 2 is even
the number 3 is odd
the number 4 is even
