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.
pow()函数用来求x的y次幂，x、y及函数值都是double型 ，其原型为：double pow(double x, double y)。实例代码如下：include<stdio.h> include<math.h> void main(){ double x = 2, y = 10;printf("%f\n",pow(x, y));return 0;} ...
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: float x = 2; float y = 3; Function call: pow(x,y); Output:...
