If else end

[CAP]

Ok I made this converter for my friend so that he can see how much things are in Canadian money compared to American money and it works, but what I would like to do is have it so it keeps looping untill someone enters a value lower than 1, and if they do it exits. This is what I have so far:

#include <stdio.h>

float userNum=0;
float userNumA=0;
#define US  1.57551;

int main(void)
{
	printf("This is a currency converter, from American dollars to Canadian\n");
	printf("Please enter the american amount now: ");
	scanf("%f", &userNum);

	if(userNum>=1)
	{
		userNumA =userNum * US;
		printf("American amount:%f  Canadian amount: %f\n\n",userNum, userNumA);
	
	}
	else
	{
		printf("Thank you for using my converter\n\n");
	}
	return 0;
}

I had originally thought of puttin a break command in the else part of if else, but that is not allowed, and I couldn't think of a way to do it with a do or for statement without it repeating over and over again, can someone help and thanks.

You can do it like this:

int main(void)
{
   while(1)
   {
      printf("This is a currency converter, from American dollars to Canadian\n");
      printf("Please enter the american amount now: ");
      scanf("%f", &userNum);

      if(userNum>=1)
         printf("American amount:%f  Canadian amount: %f\n\n",userNum, userNum * US);
      else
         break;
   }
          
   printf("Thank you for using my converter\n\n");
   return 0;
}

edit : beat me to it.

I tried out your code and it had a whole bunch of those 'undeclared identifier' errors for things like printf and scanf. Also what does while(1)do?? Is that how it loops untill someone enters a number less than 1?

> while(1)

This is always true, so it's an inifinite loop - the break statement in there means it breaks out of the loop when the condiiton is met (the input's less than 1).

As for the other error - you remembered to put the libs in, right? You didn't just copy and paste the code?

Ok I got it, I just put the while(1) on my original code and moved the break in and it works, thanks a lot .

LAME("Salem")//for Googling people to death

Well if most people would simply pull their heads out of their rectums, we wouldn't have to "google them to death". Most people, like you apparently, don't ever want to do any work themselves and just show up here expecting us to gleefully hand out the answers to every single homework / simple question without them so much as lifting a finger.

Welcome to the RealWorld(TM). Get off your collective asses and put some effort into your problem for a change.

I don't know if you are talking to me or not...but this is not an assignment, I don't go to a computer school, take any classes, or learn from anyone person(with the exception of this board of course). It is not from a book and all I asked was how to make it a little bit better, it worked just fine but I wanted to make it better.

If not though pay no attention to the above.

P.S. I do have friends who do use some of these truly simple programs and they are not made up and not for a class as mentioned above, thank you.

No, I quoted the person I was talking to.

Ya I considered that, which is why I put the do not bother with stuff above thing, but I also assumed that my question was pretty basic, and I mean within the realms of printf("") but whatever, thanks for clearing it up.

damn canadians

#include <stdio.h>

float userNum=0;

int main(void)
{
    printf("This is a currency converter, from Canadian dollars to American\n");
    printf("Please enter the canadian amount now: ");
    scanf("%f", &userNum);
    printf("American amount:%f  Canadian amount: %f\n\n", 0.0, userNum);
    return 0;
}
