What is wrong with my array code in C?

I'm writing a C code with the idea create a function input numbers into 2 arrays(Read_data) function. Then I will call it in the main function and print out those 2 arrays' elements. My relative code is as below:

 #include<stdio.h>
 #include<conio.h>
 #include<math.h>
 #define NUMBER 3
 void Read_data(double* x, double* y)
 {
// 座標値格納配列宣言
 for (int i = 0; i < NUMBER; i++)
  {
    printf_s("座標値xを入力してください:\n");
    printf_s("x[%d]= ", i);
    scanf_s("%3f", &x[i]);
  }
 for (int i = 0; i < NUMBER; i++)
  {
    printf_s("\n座標値xを入力してください:\n");
    printf_s("y[%d]= ", i);
    scanf_s("%3f", &y[i]);
  }
 }
int main()
 {
  double X[NUMBER], Y[NUMBER];
  Read_data(X,Y);
  for (int i = 0; i < NUMBER; i++)
  {
    printf("X[%d]= %f\n", i, X[i]);
  }
  for (int i = 0; i < NUMBER; i++)
  {
    printf("Y[%d]= %f\n", i, Y[i]);
  }

But when I compiled it first I input the numbers and then it appears very strange numbers that I don't know what type of errors cause this.
I will text out those number because I can't paste the picture there

座標値xを入力してください:
x[0]= 5
座標値xを入力してください:
x[1]= 6
座標値xを入力してください:
x[2]= 7

座標値xを入力してください:
y[0]= 8

座標値xを入力してください:
y[1]= 3

座標値xを入力してください:
y[2]= 9
X[0]= -92559604497122534761720676471189149555955165722294310802554880.000000

X[2]= -92559604545013020413779703294887494154402327710379908370792448.000000

Y[1]= -92559604425286806283632136235641632658284422740165914450198528.000000

What I have tried:

I have separated that Read_data() function into 2 functions each input 1 array but It still not work out.
If anyone can spot any problem in my code above then I will be very grateful!
Thank you!
