    #include<stdio.h>
    main()  {
      int power(int x, int n);
      int a, b, c;
      printf("please input X and n: \n");
      scanf("%d %d",&a, &b);
      c=power(a, b);
      printf("\n%d to the power of %d is: %d", a, b, c);
      while(1);
     }

    int power(int x, int n)
      {
	int i, p;
	p=1;
	for(i=1; i<=n; ++i)
	   p=p*x;
	return(p);
