Study Notes
Conditional Statements in C
- Conditional statements, also known as decision control structures, facilitate decision-making in C programs.
- Common types include
if,if-else, andswitch. - These statements evaluate one or more conditions to determine whether to execute a specific set of instructions.
Importance of Conditional Statements
- Real-life decision-making scenarios are mirrored in programming, requiring similar logical evaluations for flow control.
- Example of a basic conditional: If condition
xis true, execute actiony; otherwise, execute actionz. - More complex logic can be implemented using
else-ifstatements, allowing multiple conditions to be checked sequentially. - The structure of
else-ifpermits the execution of different actions based on varying conditions, exemplified by checking first forx, theny, and finally defaulting torif neither condition is met.
