Final answer:
To check if at least one condition is true out of two conditions, you can use the OR operator. If you want to check if both conditions are true, you can use the AND operator. The NOT operator can be used to negate a condition, and the XOR operator returns true if exactly one of the conditions is true.
Step-by-step explanation:
To check if at least one condition is true out of two conditions, you can use the OR operator. When using the OR operator, the overall condition will be true if at least one of the individual conditions is true. For example, if you have two conditions, A and B, you can check if at least one of them is true using the following syntax: if (A || B) { // do something }.
On the other hand, if you want to check if both conditions are true, you can use the AND operator. The overall condition will be true only if both individual conditions are true. For example, if you have conditions A and B, you can check if both are true using the following syntax: if (A && B) { // do something }.
The NOT operator, represented by an exclamation mark (!), can be used to negate a condition. It returns the opposite of the condition. For example, if you have a condition A, you can negate it using if (!A) { // do something }.
The XOR operator (exclusive OR) returns true if exactly one of the conditions is true. If both conditions are true or both conditions are false, the XOR operation will return false. For example, if you have conditions A and B, you can check if exactly one of them is true using the following syntax: if (A ^ B) { // do something }.
