Thread: Range

Code:

get the numbers
min = first number
while there are more numbers to be checked
{
   if the next number is lower than min
      set min to the next number
}
max = first number
while there are more numbers to be checked
{
   if the next number is higher than max
      set max to the next number
}

that wasn't so bad, now was it?

>How do you calculate the range of numbers using C?
Simple enough, just take the range and then print the lowest to the highest.

Code:

#include <stdio.h>
#include <stdlib.h>

static void range ( int low, int high, FILE *out )
{
  while ( low <= high ) {
    fprintf ( out, "%d ", low++ );
    fflush ( out );
  }
}

int main ( void )
{
  int low, high;

  printf ( "Enter a range of numbers (ex. 3-12): " );
  fflush ( stdout );

  if ( scanf ( "%d %*c %d", &low, &high ) != 2 ) {
    fprintf ( stderr, "Invalid input\n" );
    exit ( EXIT_FAILURE );
  }

  range ( low, high, stdout );

  return EXIT_SUCCESS;
}
