What type of code structure allows execution based on a condition?

The type of code structure that allows execution based on a condition is the If Statement. This construct enables programmers to execute a block of code only if a specified condition evaluates to true. It is a fundamental concept in programming, providing the capability to make decisions and control the flow of the program.

When the condition within the If Statement is met, the code that follows the If statement is executed. If the condition is false, the program can either skip that block of code or execute an alternative block if an Else or Else If statement is present. This structure is essential for implementing logic that responds to different states of data or user input during runtime.

The other options, while related to control flow, function differently. The Switch Case is used for multiple discrete conditions based on the value of a variable but does not offer the same conditional logic as the If Statement for true/false evaluations. The Ternary Operator is a shorthand for an If Statement, providing a more compact form to evaluate conditions, but it serves a similar purpose rather than being a standalone control structure. Loop Structures, such as For or While loops, repeat a block of code as long as a condition remains true but are not directly focused on executing a block conditionally based on a single evaluation
