    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, and switch.
    • 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 x is true, execute action y; otherwise, execute action z.
    • More complex logic can be implemented using else-if statements, allowing multiple conditions to be checked sequentially.
    • The structure of else-if permits the execution of different actions based on varying conditions, exemplified by checking first for x, then y, and finally defaulting to r if neither condition is met.
