2.
What will be the output of the program?
#include<stdio.h>
#include<stdlib.h>
union employee
{
char name[15];
int age;
float salary;
};
const union employee e1;
int main()
{
strcpy(e1.name, "K");
printf("%s %d %f", e1.name, e1.age, e1.salary);
return 0;
}

I think ascii value don't take the float value, so float value is 0.000000.

Can anyone explain why float doesn't take 75. 000000?

Why float is not sharing the same memory and not outputting as 75.000000 ?

Since union makes use of shared memory. So it allocates the memory for datatype which will take highest memory i.e int. So it will allocate 16 bit in turbo c++ and 32 bits in unix compiler. So the character 'k' will be stored in memory as the bit value of 75 as ascii value of k is 75. Since the int is also sharing this memory so it will read the same memory content with a padding of some zeros to make it 2 bytes in turboo or 4 bytes in unix.
