FIND POWER OF A NUMBER USING RECURSION USING C PROGRAM





Find power of a number using recursion using c program


#include<stdio.h>
int main(){
  int pow,num;
  long int res;
  long int power(int,int);
  printf("\nEnter a number: ");
  scanf("%d",&num);
  printf("\nEnter power: ");
  scanf("%d",&pow);
  res=power(num,pow);
  printf("\n%d to the power %d is: %ld",num,pow,res);
  return 0;
}
  int i=1;
  long int sum=1;
  long int power(int num,int pow){
      if(i<=pow){
           sum=sum*num;
          power(num,pow-1);
      }
      else
      return sum;

thank u very much

it does not works for power(10,6)...why?

Anonymous said...

it's working for (10,6) also once check it....

reny said...

can you help me with this one? program that will print out

powers of 2: 1, 2, 4, 8, .. up to 2n, where n is a user input.

It Does n't work

this power function is not efficient...
modify like this>>>>>>>
A better recursion function for power calculation...
pow(int a,int b)
{
if(b==0)
return 1;
if(b%2==0)
return pow(a*a,b/2);
return pow(a*a,b/2)*a;
}

good job

Yr what is this? It is not working. Make it right, otherwise my girlfriend will kill me. do it fast. Tomorrow will b her practicals, I am management student. Did not know what the hell are you doing with this C

try this ....this code surely works :) chancahl tripathi:)
#include
#include
int power(int x,int p);
void main()
{
int n,p;
clrscr();
printf("enter no.and power");
scanf("%d%d",&n,&p);
printf("%d",power(n,p));
getch();
}
int power(int x,int p)
{
if(p==0)
return 1;
else
return (x*power(x,p-1));

}

(i=1;i<=Thenumberyouinput;i++);
Answer=i*2

try it

this program much better this
#include
int power(int a,int b);
main()
{
int a,out;
int b;
printf("Enter Power :");
scanf("%d",&a);
printf("Enter base");
scanf("%d",&b);
out= power(a,b);
printf("power=%d",out);
getch();
}
int power(int x, int y)
{
int i,t=1;
for(i=1;i<=y;i++)
{
t=t*x;
}
return t;
}
