In this tutorial, we will learn about else-if statements in C#. We will cover the basics of conditional execution using if-else-if statements.
An else-if statement is a conditional statement that allows multiple conditions to be tested sequentially. It provides a way to execute different code blocks based on different conditions.
The syntax for the else-if statement in C# is:
if (condition1) {
// Code block to execute if condition1 is true
} else if (condition2) {
// Code block to execute if condition2 is true
} else {
// Code block to execute if none of the conditions are true
}
The else-if statement evaluates the specified conditions in order. The first condition that is true will have its code block executed; if none of the conditions are true, the code block inside the else statement is executed.
