Following are the not condition operator .

The correct answer is: C. <>

The not condition operator is used to test if a condition is not true. It is written as !. For example, the following statement will evaluate to true if the variable x is not equal to 5:

!(x == 5)

The other options are not condition operators. The greater than (>) operator is used to test if a value is greater than another value. The less than (<) operator is used to test if a value is less than another value. The mod operator is used to calculate the remainder of a division operation.

Here are some examples of how the not condition operator can be used:

• To test if a variable is not empty:
  if (!x) {
// Do something if x is empty
}

• To test if a variable is not null:
  if (!x) {
// Do something if x is null
}

• To test if a variable is not equal to a certain value:
  if (!x == 5) {
// Do something if x is not equal to 5
}

• To test if a variable is not greater than a certain value:
  if (!x > 5) {
// Do something if x is not greater than 5
}

• To test if a variable is not less than a certain value:
  if (!x < 5) {
// Do something if x is not less than 5
}
