Errors in smallest divisor program

Dear All,


I have written a program to find the smallest divisor of an input number. The code gives me an error in lines 19 and 23. The error is invalid operands to binary %. Please help me to troubleshoot, thank you. Below is my code:

Code:

---

 

• #include<stdio.h>
• #include<stdlib.h>
• #include<math.h>
• int main()
• {
• int n,r,sdivisor;
• double d,sqroot,comp;
• printf("Enter the number whose smallest divisor has to be found");
• scanf("%d",&n);
• if(n%2==0)
• {
•           printf("the smallest divisor is 2");
• }
• else
• {
• sqroot=sqrt(n);
• d=3;
• }
• comp=n%d;
• while(comp!=0 & d<sqroot)
• {
• d=d+2;
• comp=n%d;
• }
• if(comp==0)
• {
• sdivisor=d;
• }
• else
• {
• sdivisor=1;
• }
• system("pause");
• return 0;
• }

Thank you for your reply.

Code:

---

comp=n%d;

The "%" operator is not for floating point types; d is a double.

You have declared variable comp as double. But, in line 19 and 23, n%d returns integer value. When you tried to assign integer value to double using code comp=n%d, it shows error. Source: C operators :cool:

Thank you for your reply. Problem solved.
