in python a loop that does not terminate is known as a ?
a. an if-else loop
b. an infinite loop
c. a sentry loop
d. a counting loop
The for loop in (a) is converted into the while loop in (b). What is wrong? Correct it. (java language)
(a)
int sum = 0;
for (int i = 0; i < 4; i++) {
if (i % 3 == 0) continue;
sum += i;
}
(b)
int i = 0, sum = 0;
while (i < 4) {
if (i % 3 == 0) continue;
sum += i;
i++;
}

- All programming languages have a loop capability. Looping is the program logic’s ability to repeat one or more lines of code either: A set number of times, a “for loop” (i.e. 10, 100, 500, 763 or more times) An “unknown” number of times (i.e. loop terminates if a tested condition becomes “true” or as long as the tested condition remains “false”), a “while” loop, a “do until” loop, a “do while” loop. This Lab exercise demonstrates the use of the “For Loop”, a standard loop in all programming languages. C++ standard For Loop format looks like: For (n = 1; n <= 100; n++) { Loop line 1 code; Loop line 2 code; Loop line 3 code; Loop line N code; } The loop code needs: A “loop counter variable” (n in the above example) to keep track of how many iterations this loop has run A starting value (i.e. 1 in the above example) A stop test (i.e. run as…arrow_forwardWriting a while loop Write a while loop that continues to increment userValue by 5 as long as userValue is less than 0.

Sometimes, the user enters an invalid value, like $30. Use validation along with the loop-and-a-half sentinel pattern to complete this problem.arrow_forward
