C PROGRAMMING (Jump Statement)

 Jump Statements in C

These statements are used in C for unconditional flow of control through out the funtions in a program. They support four type of jump statements:

1. C break: This loop control statement is used to terminate the loop. As soon as the break statement is encountered from within a loop, the loop iterations stops there and control returns from the loop immediately to the first statement after the loop.
   Syntax:

   break;
   

   Basically break statements are used in the situations when we are not sure about the actual number of iterations for the loop or we want to terminate the loop based on some condition.
   

2. C continue: This loop control statement is just like the break statement. The continue statement is opposite to that of break statement, instead of terminating the loop, it forces to execute the next iteration of the loop.
   As the name suggest the continue statement forces the loop to continue or execute the next iteration. When the continue statement is executed in the loop, the code inside the loop following the continue statement will be skipped and next iteration of the loop will begin.
   Syntax:

   continue;
   

   

3. C goto: The goto statement in C also referred to as unconditional jump statement can be used to jump from one point to another within a function.
   Syntax:

   Syntax1      |   Syntax2
   ----------------------------
   goto label;  |    label:  
   .            |    .
   .            |    .
   .            |    .
   label:       |    goto label;
   

   In the above syntax, the first line tells the compiler to go to or jump to the statement marked as a label. Here label is a user-defined identifier which indicates the target statement. The statement immediately followed after ‘label:’ is the destination statement. The ‘label:’ can also appear before the ‘goto label;’ statement in the above syntax.
   

4. C return: The return in C or C++ returns the flow of the execution to the function from where it is called. This statement does not mandatorily need any conditional statements. As soon as the statement is executed, the flow of the program stops immediately and returns the control from where it was called. The return statement may or may not return anything for a void function, but for a non-void function, a return value is must be returned.
   Syntax:

   return[expression];
