assignment help. [urgent]

Ciaran789 · 11-29-2009, 06:01 AM

i am having huge problems continuing with an assignment due in four days.

Code:

#include <stdio.h>

void main()
{
	int maxfactorial=0, minfactorial=0, line=0, factorial=0, i=0;
	
	printf("enter max factorial\n");
	scanf("%d", &i);
	printf("enter min factorial\n");
	scanf("%d", &minfactorial);	
	printf("--------------------------------------------------------------------");
	while (line<=0){
	printf("\nFactorial Value        Factorial expression            Result");
	line=line+1;
	}
	maxfactorial=i;
	factorial=i;
	while ( factorial>=minfactorial){
	printf("\n%d" ,maxfactorial);
	maxfactorial=maxfactorial-1;
	factorial=factorial-1;
	}


}

the assignment is attached and the code above is what i have got so far. any suggestions or help no matter how small would be appreciated.

Considering this is urgent you have not really filled us in on the details, like what is the problem you are having? I cant be bothered going through an assignment question, just say what the issue is with code you posted

To print the factorial value, just make another function which returns the factorial of maxnumber. I'm modifying your code, I dont know if it's efficient or not.

Code:

#include <stdio.h>
int fact(int num)
{
	int i,facto=1;
	for(i=1;i<=num;i++)
		facto=facto*i;
	return facto;
}int main(void)
{
	int maxfactorial=0, minfactorial=0, line=0, factorial=0, i=0;
	
	printf("enter max factorial\n");
	scanf("%d", &i);
	printf("enter min factorial\n");
	scanf("%d", &minfactorial);	
	printf("--------------------------------------------------------------------");
	while (line<=0){
	printf("\nFactorial Value        Factorial expression            Result");
	line=line+1;
	}
	maxfactorial=i;
	factorial=i;
	while ( factorial>=minfactorial){
	printf("\n%d%60d" ,maxfactorial,fact(maxfactorial));
	maxfactorial=maxfactorial-1;
	factorial=factorial-1;
	}
return 0;
}

Always remember main returns int not void.

Don't give out solutions!
Newbies learn nothing if you do it.
It is they who must learn, not us. We get nothing by simply handing out solutions except create more dumb programmers out there who do not deserve their title.

thanks, i understand that bit now. one more question. do i need to use a loop to print the factorial expression?

Junky · 11-29-2009, 08:43 AM

Well, yes. The loop should go from the number (x from x!) down to 1.

But I don't get why you did this:

Code:

int maxfactorial=0, minfactorial=0, line=0, factorial=0, i=0;

...


while (line<=0){
	printf("\nFactorial Value        Factorial expression            Result");
	line=line+1;
}

You don't need a loop if you want to do something only once.

Ciaran789 · 11-29-2009, 08:49 AM

i put the while loop in because it was the only way i could get it to work. im not that good at programming yet.only in my first year.

Elysia · 11-29-2009, 08:52 AM

Start by making a flowchart.

It will work fine without the loop, you just did something else wrong.
