The pow() function raises a number to the power of another number.The pow() function is defined in the <cmath> header file.SyntaxOne of the following:pow(double base, double exponent);pow(float base, float expo
这里int c=(int)Math.pow(a,b) 中添加了一个(int),这是强制类型转换(cast), 之所以要用是因为Math.pow(a,b) 的计算结果返回是double类型,double类型转换为int类型就需要用到。 我们可以看看如果不加(int) ,程序是会提示你去 Cast to ‘int’
