How to find the absolute value in the C programming language?

In C language, the abs() function can be used to calculate the absolute value of a number.

The prototype of the abs() function is as follows:
int abs(int x);

The parameter x is a number that requires an absolute value, and the function returns the absolute value of x.

For example, the following code demonstrates how to use the abs() function to calculate the absolute value of a number:

Include the standard input/output library and the standard library.

Declare a main function that initializes a variable x to -10 and calculates its absolute value stored in abs_x.

Print the absolute value of x: %d\n”, abs_x);

End the function and return 0.

The output is:
The absolute value of x is 10.
