Question

Consider the following declaration that appears in a class other than TimeRecord.

TimeRecord $[]$ timeCards $=$ new TimeRecord $[100]$ ;

Assume that timeCards has been initialized with TimeRecord objects. Consider the following code segment that is intended to compute the total of all the times stored in timeCards.

A $5-$line code segment reads as follows. Line $1$: Time Record total equals new Time Record, open parenthesis, $0$ comma $0,$ close parenthesis, semicolon. Line $2$: for, open parenthesis, int k equals $0,$ semicolon, k less than time Cards, dot, length, semicolon, k$,$ plus, plus, close parenthesis.

Line $3$: open brace. Line $4$: forward slash, asterisk, missing expression, asterisk, forward slash, semicolon. Line $5$: close brace.

Which of the following can be used to replace $/*$ missing expression $*/$ so that the code segment will work as intended?

Responses

timeCards $[$ k $].$advance $()$

timeCards $[$ k $].$advance $()$

total $+=$ timeCards $[$ k $].$advance $()$

total $+=$ timeCards $[$ k $].$advance $()$

Option C shows a $2-$line code segment that reads as follows. Line $1$: total, dot, advance, open parenthesis, time Cards, open square bracket, k$,$ close square bracket, dot, hours comma. Line $2$: time Cards, open square bracket, k$,$ close square bracket, dot, minutes, close parenthesis.

Option D shows a $2-$line code segment that reads as follows. Line $1$: total, dot, advance, open parenthesis, time Cards, open square bracket, k$,$ close square bracket, dot, get Hours, open parenthesis, close parenthesis, comma. Line $2$: time Cards, open square bracket, k$,$ close square bracket, dot, get Minutes, open parenthesis, close parenthesis, close parenthesis.
