Please help!!

This C stuff is driving me up the wall.....can someone help me please.......

Is there a way to list all the odd numbers when the user enters 2 integers (second number bigger than first number)

Is there a key word that I should be listing, or a specific variable that I should declare so that it will print out only odd numbers...


I thought about it, something like rand() to list random numbers, between a certain number......

but what if the user enters 2 as 1st num... and 400 as 2nd number.... how does it know to only pick out the odd numbers.....

PLEASE HELLP......I'm soooo lostttt!!!

I don't normally just give answers

Code:

#include <stdio.h>

int main() {
    int low, high, count;
    printf("Enter Lower bound: ");
    scanf(" %d",&low);
    printf("Enter Upper Bound: ");
    scanf(" %d", &high);
    
    count = low;
    while (low <= high) {
        if (count %2 == 1) {
            printf("%d\n",count);
        }
    }
    return 0;
}

In this last post (sample code by kwigibo), you can substitute this
>if (count %2 == 1) {

for this:
>if ( (count & 01) == 1) {

to avoid the arithmatic being performed. It gives the same result, but is slightly more efficient (I believe!).

Opps, just noticed your loop is infinite, you aren't changing the value of the loop control variables. A better version might be:

Code:

#include <stdio.h>

int main(void) 
{
    int low, high;
    
    printf("Enter Lower bound: ");
    if (scanf(" %d",&low) != 1)
    	{ printf ("Invalid"); return 1;}
    
    printf("Enter Upper Bound: ");
    if (scanf(" %d", &high) != 1)
    	{ printf ("Invalid"); return 1;}
    
    if ((low & 01) == 0) low++;
    
    for (; low <= high; low += 2)
    	printf("%d\n",low);
    return 0;
}
