An if-else statement is a programming construct that allows the program to make decisions based on certain conditions. It checks a condition and executes one block of code if the condition is true, and another block of code if the condition is false.
congrats on reading the definition of if-else statement. now let's actually learn it.
Two-way selection: A two-way selection refers to making a decision between two options based on a condition. It involves using an if-else statement to execute different blocks of code depending on whether the condition is true or false.
A condition in programming refers to an expression that evaluates to either true or false. It determines which block of code will be executed in an if-else statement.
Nested if statements are multiple levels of conditional statements within each other. They allow for more complex decision-making by checking multiple conditions and executing different blocks of code accordingly.
