e do loop differs from the while loop in that a. the while loop will always execute the body of the loop at least once b. the do
loop will always execute the body of the loop at least once c. the do loop will continue to loop while the condition in its while statement is false and the while loop will continue to loop while the condition in its while statement is true d. the while loop will continue to loop while the condition in its while statement is false and the do loop will continue to loop while the condition in its while statement is true e. None of these; there is no difference between the two types of loops
b. the do loop will always execute the body of the loop at least once
Explanation:
The do loop will always execute the body of the loop at least once becuase it is an exit loop, that means the condition is always checked at the end, where as while loop execute hte body of the loop zero times as it is an entry loop and the condition will be checked prior to the execution of body of the loop.
do loop structure is as shown below
do{
}while()
So it executes the block atleast once and then checks the condition
Hence, the do loop will always execute the body of the loop at least once.
SQL injection is a vulnerability in databases that occurs when user input is not properly validated. Hackers are able to input SQL query statements to bypass the use of the actual user name and password to gain access to the account.
Using placeholders in programmed SQL statements mitigates the effects of SQL injection.
