What does x*x mean in c language

In C language, xx means x times x, which is the square of x. Calculation method: The operator represents multiplication, and the result of the xx operation is a new value, representing the square of x. For example, if num is set to 5, numnum will be 25. Note: if x is a floating point number, the result is also a floating point number; if x is negative, the result is a positive number; x*x is different from x^2, which represents the square of x, where the ^ operator represents the exponent.

The meaning of x*x in C language

In C language, x*x means x multiplied by x. It is a mathematical expression that calculates the square of x.

Expansion description

• * Operator represents multiplication.
• x is a variable or constant that represents the number to be squared (multiplied by itself).
• x*x The result of the operation is a new value representing x squared.

Example

For example, the following code declares a variable num and sets it to 5, then num# The square of ## (num * num) is stored in another variable square:

<code class="c">int main() {
    int num = 5;
    int square = num * num;
    return 0;
}</code>

Running this code will produce the value of

square 25 (5 squared).

Notes

If
• x is a floating point number, the result of the x*x operation is also a floating point number.
If
• x is a negative number, the result of the x*x operation is a positive number, because the square of a negative number becomes a positive number.
• x*x is a different operation than x^2. The x^2 operation represents the square of x, where the ^ operator represents the exponent.
