Answer:
"The question mark quantifier "?" will match the preceding element exactly one time" is the correct answer to the given question .
Explanation:
The Quantifiers are defined as it determine how the several occurrences of a set of symbols, categories, or the characters should be found throughout the input to searching the matches.
- The * quantifier in the regular expression corresponds the zero or more then zero to the previous item. it is represented by {0,} quantifier
- The + quantifier in the regular expression appears to fit in one or more times with the previous item. it equates with {1} quantifier.

Answer:
for (i = lo, result = 0; i <= hi; result += i, i++) {}
Explanation:
A for loop header has three statements:
- <em>i = 0, result = 0; </em>This statement initializes <u>i</u> and <u>result</u> variables with 0. It is executed only once at the very start of the for loop.
- <em>i <= hi;</em> This statement is executed after the first statement and again after the execution of code in body of the loop.
- <em>result += i, i++</em> This statement is executed after the execution of code in body of the loop but before the execution of second statement.
Therefore, the following sequence of events will occur:
- The result variable is initialized with 0 at start.
- Then, the condition is checked. If the value of i will be less than or equal to the value of hi, the third statement will be executed.
- The third statement will add the value of i to the value of result and then increase the value of i by 1.
- Then, again the condition in second statement will be checked.
This loop will be executed for as long as the condition remains true.
