sizeof(datatype)
write a program that reads in the size of the side of square and then pints a hollow square of that size out of asterisks and blanks?
It completely depends the datatype that you have assigned for the variables 'a' , 'b' , and 'c'. Check the compiler that you are using for the size of the datatype in bytes. Add them and thus you will get the answer.
Write a program in c++ that take input in a integer matrix of size 4*4 and find out if the entered matrix is diagonal or not.
like this: sizeof(int); replace int with the kind of data you want to find the size of. of course, to be able to do anything with this size data, you'll have to store it into a variable or display it or something.
you can write by two ways 1 by giving the size of array at declaration 2 by checking condition
Importance of union in 'C':unions are the concept borrowed from structures in structures we allow different datatypes in which each datatype is allocated a separate memory location .But in unions same as structures we use different data types but all the datatypes will be allocated to a single memory location and only one datatype with maximum size will be used for allocation of all the data types used in a union program.Sample code for union is as follows:union item {int m;float c;char x;}code;In the above program we used three kinds of datatypes here integer size is 4 so the other data types will be shared in the same location of size 4.then the memory will not be wasted and all the memory will be utilized perfectly.
Long variables are stored as signed 64-bit (8-byte) integers ranging in value from -9,223,372,036,854,775,808 through 9,223,372,036,854,775,807.
In her early years Sally Lowenthal, better known as Sally Jessy Raphael, an American talk show host, known for her talk show program 'Sally' wore size 24.

A double is a floating point type, greater than or equal in size to a float.
Functions are very important in C++, as you can't write the simplest program to print hello without using a function. Overall you can say that function are building blocks of a C++ program. Functions can also be defined by the programmer to reduce program size.
Datatype represents the type of data like integer, varchar2 etc. Example name varchar2(20) it denotes that name is an attribute of character and size is 20 characters .
