Can somebody please tell me what to put in my code for positive integer division if someone enters a negative number...?? This is my code:
/*integer division using 2 positive integers
*/
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
{
main ()
int dividend = N;
int didvisor = D;
int quotient = Q;
int remainder = R;
printf("Enter a positive whole number to be used as the dividend");
scanf("%d", &N);
printf("Enter a positive whole number to be used as the divisor");
scanf("%d", &D);
//perform the integer division
Q = N/D;
printf("\n The quotient is %d", Q);
//perform the modulus
R = N%D;
printf(("\n The remainder is %d", R);
return 0;
}
/*integer division using 2 positive integers
*/
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
{
main ()
int dividend = N;
int didvisor = D;
int quotient = Q;
int remainder = R;
printf("Enter a positive whole number to be used as the dividend");
scanf("%d", &N);
printf("Enter a positive whole number to be used as the divisor");
scanf("%d", &D);
//perform the integer division
Q = N/D;
printf("\n The quotient is %d", Q);
//perform the modulus
R = N%D;
printf(("\n The remainder is %d", R);
return 0;
}

What is N, D, Q, R? If they are variable you should define them as
int N, D, Q, R;
You can always check whether N, D are positive or not before you do the division.
if (N >= 0 && D > 0)
{
Q = N/D; R = N%D; /* ... */
}
else printf("Error, should be +ve");
You can also define
unsigned int N, D, Q, R;
and use %u in the printf statement. But that's not recommended.

if (N >= 0 && D > 0)
{
Q = N/D; R = N%D; /* ... */
}
else printf("Error, should be +ve");

and use %u in the printf statement. But that's not recommended.
You can first check whether the input number is positive or not before handling it, like this:
scanf("%d", &N);
/* set a while loop to check if N is a non-positive number */
while(N<=0) printf("Please enter a POSITIVE INTEGER!\n");
/* until the input is valid, the while loop will no longer be satisfies and the following code will be generated then */
scanf("%d", &N);
/* set a while loop to check if N is a non-positive number */
while(N<=0) printf("Please enter a POSITIVE INTEGER!\n");
/* until the input is valid, the while loop will no longer be satisfies and the following code will be generated then */
Try to use the good old friend abs() liket this:
//perform the integer division
Q = abs(N)/abs(D);
printf("\n The quotient is %d", Q);
//perform the modulus
R = abs(N)%abs(D);
printf(("\n The remainder is %d", R);
return 0;
//perform the integer division
Q = abs(N)/abs(D);
printf("\n The quotient is %d", Q);
//perform the modulus
R = abs(N)%abs(D);
printf(("\n The remainder is %d", R);
return 0;
Hi missq,
First you declare N,D, R, &Q as integers and you have to assign some value to them. Then you check for just greater than zero (D or N > 0) nor for D or N >=0
O.K.
