How to express third power in c language

In C language, there are two common ways to express cube: pow function: used to calculate the power of any number. Power operator (**): Used to raise positive integer powers of an integer.

Representing cubes in C language

In C language, there are two common ways to express cubes:pow function and exponentiation operator () **.

pow function

The pow function is a mathematical function provided in the C standard library and is used to calculate the power of any number. The syntax is as follows:

double pow(double base, double exponent);

Among them, base is the base and exponent is the exponent. For example, to calculate 2 raised to the third power, you would use the following code:

double result = pow(2, 3);

Power Operator ()

Power Operator (**) can be used Calculates the positive integer raised to the power of an integer. The syntax is as follows:

int result = base ^ exponent;

Among them, base is the base and exponent is the exponent. For example, to calculate 2 raised to the third power, you can use the following code:

int result = 2 ^ 3;

Note

• The pow function can calculate any number raised to any power, Includes floating point numbers. The power operator can only calculate positive integer powers of an integer.
• When exponent is a negative number, the pow function returns NaN (not a number).
• When exponent is 0, the pow function returns 1.
• When base is 0, the behavior of the pow function is undefined.
