    How to calculate a power value of a given number

    The logic is something–
    2. Check out how much is the power to be calculated
    3. multiply the given number in 1 for these many times (given in step-2) 
    Say i have a number called 2  (getting in logic no-1)
    i need to calculate the 2 to the power 4 value(getting 4 at logic no-2)
    So output of that is 2*2*2*2=16

    Let us implement that in code.

        public  void calcpow(int val,int powr) {
    //this function takes two input …the number and the power value
            int res=1;
      //res is the integer type temp variable  This is initialized to 1 to handle the condition where power=0. x to the power 0=1
            for(int i=1;i<=powr;i++) {
               res=res*val;
             
            }
            System.out.println(res);
        }
