Branch Structure
The concept of branching in programming is similar to the concept of branching on a highway, whose determination of direction is determined based on the purpose of the user. Direction here shows the part of the program to be executed, while the destination is input data that is used branching to make decisions. In general, branching is described as follows

Types of Branching

1. If
2. Else If
3. Else
4. Switch

Make a branch

If written in the format the program code is stated as follows.

Programmatically fulfilling this condition means that the condition has a true boolean value. The program block to be executed is placed in curly brackets. The following is an example of a program with conditions that will generate true or false according to the input of the given age.

The following are other formats that can be used to accept inappropriate conditions.

For conditions more than one can also be made using the following format.

Switch

Switch is another form of branching. This concept is useful if the conditions to be determined have a certain value. The format of the switches is as follows.

In the example program above if the user chooses 1, there will be a message "The amount of your credit is nineteen thousand rupiah" displayed. If the choice is not in the switch-case block, the default part will be executed.

The break statement in the above program is used to exit the selected case or default block. If there is no break, the case block and / or default below it will also be executed.
