Study Notes

Decision Control Statements

C programs execute code sequentially from the first line to the last line.
The second statement is executed after the first, the third statement is executed after the second, and so on.

Types of Decision Control Statements

Conditional type branching: helps to jump from one part of the program to another when a particular condition is satisfied.
Unconditional type branching: changes the flow of a sequence of instructions.

Conditional Branching Statements

Used to determine which statements of the code should be executed and which should be ignored.
Examples of conditional branching statements include:
- if-statement
- if-else statement
- nested if-else statement
- switch-case statement
