Question

Consider the following incomplete code segment, which is intended to increase the value of each digit in a String by one. For example, if num is 12345, then the resulting String would be 23456.
String num = "12345";
int counter = 0;
String result = "";
while(/* Missing Loop Header */)
{
int newNum = Integer.valueOf(num.substring(counter,counter+1));
result+= (newNum + 1);
counter++;
}
System.out.println(result);

Which of the following should replace /* Missing Loop Header */ so that the code segment works as intended?

counter < num.length() - 1


counter <= num.length()


counter < num.length()


counter > num.length()


counter < num.indexOf(counter)

Answer 1

The instruction that should replace /* Missing Loop Header */ so that the code segment works as intended is (c)  counter < num.length()

Loops

The program is an illustration of loops (the while loop)

While loops are program statements that are used to perform repeated operations

For the string to return 23456, the while loop body must be repeated as long the counter is less than the length of the string num

Hence, the missing loop header is counter < num.length()
