Size of float, double and long double in Bytes are?

The size of float, double, and long double in bytes can vary depending on the system and compiler, but generally, they are as follows:

1. Float: A float is usually 4 bytes in size.
2. Double: A double is usually 8 bytes in size.
3. Long Double: A long double can be from 8 to 16 bytes in size, depending on the system and compiler.

Please note that these sizes can vary, and you can use the sizeof operator in C/C++ to determine the exact size on your system.
