Question

#include <stdio.h>
int main(void) {
	double a=30;
	int r:
	r=a%5;
	printf("\n r=%d",r)
	return 0;
}

Why this code is throwing compilation error ?

Comments

what is value of n.

---

r = n%5; undefined symbol n.

---

That was a typo :D

---

@Anu007 it isn't because of type mismatch, it's because modulus operator doesn't work on floats and doubles

---

any refference for such properties .BDW thanks

---

there is no semicolon(;) after printf and int r its syntax error.

---

also it will give symantic error, because modulus(%) can only be used with integral values.

---

nitish any refference for such property like mod used with int only...
