C has GOTO statement but one must ensure not to use too much of goto statement in their program because its functionality is limited and it is only recommended as a last resort if structured solutions are much more complicated. First let us see what the goto statement does, its syntax and functionality. The goto is a unconditional branching statement used to transfer control of the program from one statement to another.

switch statement is generally best to use when you have more than two conditional expressions based on

a single variable of numeric type. For instance, rather than the code

No, but it is not a bad idea to put default statements in switch statements for error- or logic-checking

purposes. For instance, the following switch statement is perfectly normal:

Switch statement is a powerful statement used to handle many alternatives and provides good presentation for C program. But there are some limitations with switch statement which are given below:

Logical operators cannot be used with switch statement. For instance

case k>=20:

is not allowed

Switch case variables can have only int and char data type. So float or no data type is allowed.

For instance in the switch syntax given below:

switch(ch)
{
case 1:
statement-1;
break;
case 2:
statement-2;
break;
}

In this ch can be integer or char and cannot be float or any other data type.
