Question { Persistent, 15854 }

How much is size of struct having 1 char & 1 integer?

Answer

as the size of char in C++ and C is one byte and the size of
int in C++,c is 2 byte so when we illl call that struct then
the memory will assigned the contents of these char and
int's variables
But
Char in C# and java is of 16 bit and in is of 32 bits and
double of 64 bits so the size of struct is depends upon
these languages.
