Power of a number

We can calculate the power of a number either by using the library function pow(); under the <math.h> library and we using common method to calculate repeated multiplication method

eg : Number is 2 and power is 3 means mathematically 2 power 3…..so sum=sum*num

so

1=1*2 the result is 2

2=2*2 the result is 4

4=4*2 the result is 8
