There is something wrong with my solution, but i can't figure out. The instruction is:

"Write a program that will compute for a raised to x (x as a's exponent) given real value a and positive integer x."

And here's my code:
CODE

#include <stdio.h>

main()
{
  int nNum, nExp, i;

  printf("Enter a real number: ");
  scanf("%d", &nNum);
  printf("Enter a positive integer for the exponent: ");
  scanf("%d", &nExp);

  for (i = 0; i <= nExp; i++)
  {
    nNum *= nNum;
  }

printf("%d", nNum);

}


Thanks in advance.

Hi, try this code:
Try to understand what I did in that code that is different that what you did in yours. Feel free to post again if you run into some problems again. Enjoy smile.gif

CODE
#include <stdio.h>

main()
{
  int nNum, nNum1, nExp, i;

  printf("Enter a real number: ");
  scanf("%d", &nNum);
  printf("Enter a positive integer for the exponent: ");
  scanf("%d", &nExp);
  nNum1=nNum;

  for (i = 0; i < nExp-1; i++)
  {
    nNum1 *= nNum;
  }

printf("\n%d\n", nNum1);
return 0;

}
