In this tutorial, you will learn the difference between char array and char pointer (char [] vs char *). Both array and pointer have a close relationship to each other but both are different types and have different concepts in C programming. You can consider other important topics: Difference between pointer and array in C.

The exp function in C computes the base-e exponential of x. A range error occurs if the magnitude of finite x is too large. The x is the argument that is passed into the exp(). It is declared in math.h and takes one argument in the form of double and returns the value of type double. Syntax
The log2 function in C computes the base-2 logarithm of x . A domain error occurs if the argument is less than zero. A pole error may occur if the argument is zero. The x is the argument that is passed into the log2(). It is declared in math.h and takes one argument in the form of double and
