A counter example is a proof of a negation of a universal statement.
A statement of the form "all X are Y" (e.g. all men are mortal), can be disproved by providing a counter example (here: something (someone) which is both a man and immortal).
A more mathematical example of the use of a counter example could be to disprove the statement "the product of two prime numbers is odd". This is a claim about all numbers which are the product of two prime numbers (all elements in the set {n in N | n = p*q where p and q are prime numbers}). This set contains infinitely many pair numbers, but a single example (or witness), is enough to disprove the statement. Four is such a number and can serve as a counter example.

How can you use the word counter in a sentence?
It can be used in a number of ways. For example, "The legislator's plan ran counter to what his party was trying to accomplish as a whole." Counter in this sentence means against, literally in opposition to. Here's another example, "They set the groceries on the counter." Counter used here refers to the flat surface in most kitchens.

Turning a while loop to a for loop?
A for loop is just a while loop with a built-in counter. For example, the following programs are functionally identical: While loop: int counter = 0; while(counter < 10) { printf("counter = %d\n", counter); counter++; } For loop: for(int counter = 0; counter < 10; counter++) { printf("counter = %d\n", counter); }
What does counter example mean in math terms?
It is an example that demonstrates, by its very existence, that an assertion is false. Usually experience suggests that the assertion is true: there is a large amount of supporting "evidence" but the statement has not been proven. The counter-example, though demolishes the assertion For example: Assertion: all prime numbers are odd. Counter example: 2. It is a prime but it is not odd. Therefore the assertion is false. This was a favourite "trap" at GCSE exams in the UK. Assertion: if you divide a nuber it becomes smaller. Counter example 1: 2 divided by a half is, in fact, 4. Counter example 2: -10 divided by 2 is -5 (which is larger by being less negative).
What is spawn's counter?
The counter represents the amount of magic power he is using up. The counter starts at 9:9:9:9 and every time for example, gets into a fight, the counter drops.
