Which of the following statements is true about the `for` loop in C?

The correct statement regarding the for loop in C is that it initializes variables within its scope only. This is because the initialization section of a for loop allows you to declare and initialize variables that will be used to control the loop. These variables are typically scoped to the loop itself, meaning they cannot be accessed outside of the loop after its execution.

When a variable is defined within the initialization part of the for loop, it is limited to that block of code. This helps to prevent potential variable name conflicts and keeps the variable's lifetime restricted to the loop, enhancing code readability and maintainability.

In contrast, the other options either misrepresent the nature of the for loop or its functionality. For example, the assertion that it should always run at least once is incorrect, as a for loop may not execute at all if its condition is false from the start. Similarly, stating that it repeats a block of code while a condition is true better describes a while loop than the for loop, which is specifically structured for initialization, condition checking, and incrementing/decrementing in one line. Lastly, the claim that it is not suitable for iterating over arrays is misleading; for
