struct in c

[haidarrrr]

Hi !

I'm trying to build a program that can convert polar to polar to cartesian using struct variables1 but here i came across a problem witch is when i scanf the values of (a&b) it telles me that i have to enter yet a another one !!

the code is !

#pragma warning(disable:4996)
#include<stdio.h>
#include<stdlib.h>
#include<math.h>
void PolarTo_Cartesian(double r, double d, double *q, double *u);

struct MyStruct
{
	double x;
	double y;
}; 

int main(){

	printf("enter ur cord\n");
	
	struct MyStruct a;
	struct MyStruct b;

	a.x; // puting value to x  
	b.y;

   scanf("%lf\n", &(a.x));
   scanf("%lf\n", &(b.y));

    PolarTo_Cartesian(a.x, b.y, &(a.x), &(b.y)); // to store the address so i can change its value !!
   printf("the valus is (%lf,%lf)\n",a.x,b.y);

	system ("pause");

	return 0;
}
void PolarTo_Cartesian(double r, double d, double *q, double *u) {

	*u = r*(sin(d));
	*q = r*(cos(d));

}

replace the scanf with this that is remove the newline.

   scanf("%lf", &(a.x));
   scanf("%lf", &(b.y));
