Write a C callable assembler function named "count" that counts the number of times a user-entered character appears in a user-entered string. The function should take two arguments: a pointer to the string and the character to be counted. Use a stack frame and return the count in %eax. Store all data as 32-bit quantities.

int count(char *str, char c)
{
  int count = 0;

  while (*str != '\0')
    if (*str++ == c)
      count++;

  return count;
}
