Basics
M If Else
Conditional Statements
M if-else statements control data flow with then and else.
Introduction to M If-Else Statements
The if-else statement in the M language is a fundamental control structure that helps manage the flow of data and execute code conditionally. These statements allow you to perform different actions based on whether a specific condition evaluates to true or false.
Basic Syntax of If-Else
The basic syntax for an if-else statement in M is straightforward. The condition is evaluated, and if it is true, the code block within the then clause is executed. If false, the code within the else clause is executed.
Example: Checking a Number
Let's consider an example where we check if a number is positive, negative, or zero. This will demonstrate the use of nested if-else statements in M.
Using If-Else in Loops
If-else statements are often used within loops to make decisions on each iteration. This allows for dynamic control over the flow of the loop based on changing conditions.
Conclusion
The if-else statement is a crucial part of the M programming language, providing a way to control the flow of execution based on conditions. By understanding and utilizing if-else statements, you can write more dynamic and responsive code.
