while loop

Hi i have this program and have a problem it is a basic program for exponents and now i need to add a while loop so that if the user enters a number greater that 10 it asks them to input a number lower or equal to 10, here is my code can someone help me?.

#include <stdio.h>

main( )

{

 /*  y  */

 /* calculate x  */

 /*    */

 /* where x and y are integers and y >= 0 */

 int base, power;

 long result = 1;

 int counter = 0;

 

 while ( x <= 10);

  

 



 printf("Enter the base number : ");

 scanf("%d",&base);

 printf("Enter the nth power to which base will be raised");

 scanf("%d",&power);

 {

 for (counter++ < power)

  result = result * base;

 }

 printf("The base of %d raised to",base the %dth power is %

ld\n",power,result);

 

 return 0;

 

}}}

Re: while loop

1. Please edit your post to use code tags to preserve spacing and tabs.

2. main() must be declared like this:

int main()

{

   // blabla





  return 0;

}

I realize neither of the above answer your questions, but fix those and we will look at your post again.

Re: while loop

x is not declared as a variable anywhere that I can see. this should give a complier error.
Also, your while statement is terminated by a semicolon. This would work for do-while statement but not when the using a while by itself. If using a while in this way it should be followed by braces surrounding the code to be executed during each iteration of the loop.

This also has another problem, bacause when x is declared the program will just stay on this line ( while(1) )

Quote:

 

for (counter++ < power)

I think what you're trying to do is:

 

for (counter = 0; counter < power; counter++)

{

}

Quote:

result = result * base;

hmmm, int to long conversion....
