How can you create alternative paths of execution in C++?

Creating alternative paths of execution in C++ is accomplished by using conditional statements or switch cases. Conditional statements, such as if, else if, and else, allow the program to evaluate conditions and execute different blocks of code based on whether those conditions are true or false. For instance, if you want to check whether a user's input meets specific criteria, you can use an if statement to execute one set of instructions if the condition is met and another set if it is not.

Additionally, the switch statement provides a way to execute code based on the value of a variable. This is particularly useful when you have multiple discrete cases to handle without needing multiple if statements. When the program runs, it evaluates the cases and jumps to the corresponding block of code for execution.

Using these constructs, programmers can effectively manage program flow and implement decision-making processes, which results in more dynamic and responsive applications.

In contrast, relying solely on loops does not provide alternative paths; loops are designed primarily for repeated execution of code blocks under certain conditions, rather than branching logic. Defining global variables does not affect the flow control of the program itself; it merely affects the scope and accessibility of data. Creating multiple main functions is not valid in
