Type casting error in pointer in C -

i can't type casting of pointer.. have found garbage value of y. doing wrong in code?. please me find desire output

#include<stdio.h>  int main(){      float x= 15;     int *y;      y=(int *)&x;      printf("\tvalue of x : %f \n",x);     printf("\tvalue of y : %d",*y);      return 0; } 

output

float x= 15; int *y;  y =(int *)&x; 

assigning address of float pointer int undefined behavior, not same type , not interchangeable, types allowed char * , void *.

change to:

float x= 15; char *y;  y = (char *)&x;  printf("\tvalue of x : %f \n", x); printf("\tvalue of y : %d", (int)*(float *)y); 

or

float x= 15; void *y;  y = &x;  printf("\tvalue of x : %f \n", x); printf("\tvalue of y : %d", (int)*(float *)y);
