Syntax of pow() function: pow(x, y); Parameter(s) x, y– are the numbers to calculatex^y. Return value double– it returns double value that is calculate result ofxto the power ofy. Sample Input and Output Input
In thisC++ Tutorial, we learned the syntax of C++ pow(), and how to use this function to find the value of a number raised to a power, with the help of examples.

In a C program, unless you're using the <tgmath.h> macro to call this function, pow always takes two double values and returns a double value.If you use the pow macro from <tgmath.h>, the type of the argument determines which version of the function is selected. See Type-generic ...
4)Type-generic macro: If any argument has typelongdouble,powlis called. Otherwise, if any argument has integer type or has typedouble,powis called. Otherwise,powfis called. If at least one argument is complex or imaginary, then the macro invokes the corresponding complex function (cpowf,cpow...
