Can I use string in C?

The C language does not provide an inbuilt data type for strings but it has an access specifier “%s” which can be used to directly print and read strings. You can see in the above program that string can also be read using a single scanf statement.

What is the size of an object?

Objects, References and Wrapper Classes. Minimum object size is 16 bytes for modern 64-bit JDK since the object has 12-byte header, padded to a multiple of 8 bytes. In 32-bit JDK, the overhead is 8 bytes, padded to a multiple of 4 bytes.

What is string C++ example?

One of the most useful data types supplied in the C++ libraries is the string. A string is a variable that stores a sequence of letters or other characters, such as “Hello” or “May 10th is my birthday!”.

What does a typedef do?

The typedef keyword allows the programmer to create new names for types such as int or, more commonly in C++, templated types–it literally stands for “type definition”. Typedefs can be used both to provide more clarity to your code and to make it easier to make changes to the underlying data types that you use.
