pow() is a function in C/C++ defined in <math> header which is used to calculate power of a number
For example
pow(2,3) is same as 2^3 in maths
pow(2,3) == 2*2*2 == 8

Samsil Arefeen it's not necessary to use <cmath> header file, you can also use good old <math.h> header file in C++.
The main difference between them is <cmath> defines symbols in the std namespace, and may also define symbols in the global namespace whereas <math.h> defines symbols in the global namespace, and may also define symbols in the std namespace.
take this for example👇
