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
