Final answer:
The missing statement should be a while loop that checks if the variable a is less than or equal to 10. It will cause the code to repeat until a is greater than 10, and should be followed by logic to increment a to avoid an infinite loop.
Step-by-step explanation:
The student is asking about how to control the flow of a loop in programming. To make the given code repeat until the variable a is greater than 10, you would use a loop that checks the condition before each iteration. In many programming languages, such as Python, JavaScript, or C, a common structure to use would be a while loop. The structure of the while loop is such that it checks a condition before executing the code block, and if the condition is true, the code within the block is executed. If you want to repeat the code until the variable a is greater than 10, the condition should read a <= 10.
The missing statement for the provided code should be something along the lines of:
while (a <= 10) {
// Code to be repeated
}
This will ensure that the loop continues to run as long as a is less than or equal to 10. Each time the loop runs, you should include logic within the loop to modify the value of a to eventually meet the exit condition of the loop and avoid an infinite loop.
