How do you do powers in C?

pow() is function to get the power of a number, but we have to use #include h> in c/c++ to use that pow() function. then two numbers are passed. Example – pow(4 , 2); Then we will get the result as 4^2, which is 16.

What is a double in C?

A double is a data type in C language that stores high-precision floating-point data or numbers in computer memory. It is called double data type because it can hold the double size of data compared to the float data type. A double has 8 bytes, which is equal to 64 bits in size.
