Question

1. What is unusual about the logical operators?

2. What is a possible problem using continue in while statements?

Answer 1

Logical operators:

IS EQUAL TO == <--- yes, there are TWO (2) equal signs

back to back

NOT EQUAL TO != <-- The EXCLAMATION POINT ! usually

means NOT or NEGATION

GREATER THAN >

LESS THAN <

GREATER THAN OR EQUAL >=

LESS THAN OR EQUAL <=

continue statement:

The continue statement in C programming works somewhat

like the break statement. Instead of forcing termination,

it forces the next iteration of the loop to take place, skipping any code in between.

For the for loop, continue statement causes the conditional test and

increment portions of the loop to execute. For the while and do...while loops,

continue statement causes the program control to pass to the conditional tests.

so in the while loop case, any code after the continue statement gets skipped,

which is dangerous
