How Can I Correctly Use Multiple OR Conditions in an if Statement?

Can You Utilize Multiple OR Conditions in an if Statement?

You may have encountered a situation where you wanted to evaluate multiple OR conditions within an if statement. However, you might have stumbled upon an unexpected result, such as always getting the first condition returned. This is where the syntax comes into play.

In your provided code:

if (number==1||2||3) {
    // ...
}

The error lies in the syntax. The correct way to write multiple OR conditions is:

if (number==1 || number==2 || number==3) {
    // ...
}

By using this syntax, each condition is properly separated by the OR operator (||). This ensures that the evaluation will consider each condition individually.

The reason your original syntax didn't work is that it interprets the code as:

if ((number == 1) || 2 || 3) {
    // ...
}

This expression evaluates to true regardless of the value of number because 2 and 3 are both non-zero values, which are considered true in C .

Therefore, when using OR conditions in an if statement, remember to separate each condition with the OR operator (||) to ensure the correct evaluation.
