!x is equal to what in c language

In C language, the "!x" operator performs a logical NOT operation on the expression x, which converts a true value into a false value and vice versa: if x is true (non-zero), ! x is false (0). If x is false (zero), !x is true (non-zero).

In C language, the "!x" operator represents the logical negation of the expression x.

The logical NOT operator converts a true value to a false value and vice versa. This means:

• If x is true (non-zero), !x is false (0).
• If x is false (zero), !x is true (non-zero).

For example:

<code class="c">int x = 5;
int result = !x; // result 现在为 0（假）

x = 0;
result = !x; // result 现在为 1（真）</code>
