Understanding Control Flow in Programming: If, Then, Select Case, and Loops

This guide explores essential control flow structures in programming, including If, Then, Else, and Select Case statements. Learn how to use the Select Case statement to execute the first true condition, similar to the Switch structure in C++ and Java, which allows executing all matches until a break statement is encountered. Additionally, we cover loop structures like Do While, While Wend, and For Next loops, including how nested control statements function effectively. Perfect for beginners and seasoned developers!
