Hana is easy to extend in a ad-hoc manner and it provides out-of-the-box inter- operation with Boost.Fusion, Boost.MPL and the tuple, General purpose index- based heterogeneous sequence with a fixed length. Use this as a std::vector for 

C++ Arithmetic Operators. Advertisements. Previous Page. Next Page . Try the following example to understand all the arithmetic operators available in C++. Copy and paste the following C++ program in test.cpp file and compile and run this program. Live Demo. a+b = 13 a-b = 5 a*b = 36 a/b = 2 Remainder when a divided by b=1. The operators +, - and * computes addition, subtraction, and multiplication respectively as you might have expected. In normal calculation, 9/4 = 2.25. However, the output is 2 in the program. It is because both the variables a and b are integers. Operators Once introduced to variables and constants, we can begin to operate with them by using operators.What follows is a complete list of operators. At this point, it is likely not necessary to know all of them, but they are all listed here to also serve as reference. (pointer) + (int) = (pointer) p + n moves the pointer p forward n elements in the array. (Note that if n is negative, this is really moving backward.) (pointer) - (pointer) = (int) p1 - p2 returns the number of elements that are between the two pointers. Note that these operations are defined only when they make sense.

C program to find diameter, circumference and area of circle. C program to convert length from meter to kilometer. C program to convert temperature from Celsius to Fahrenheit. Because writing statements such as x = x + 4 is so common, C++ provides five arithmetic assignment operators for convenience. Instead of writing x = x + 4, you can write x += 4. Instead of x = x * y, you can write x *= y. Thus, the above becomes:

Pointer arithmetic, arrays, and the magic behind indexing In the section above, you learned that arrays are laid out in memory sequentially. In lesson 6.8 -- Pointers and arrays , you learned that a fixed array can decay into a pointer that points to the first element (element 0) of the array.

In computer science, a pointer is a programming language object that stores a memory address. This can be that of another value located in computer memory, or in some cases, that of memory mapped computer hardware. A pointer references a location in memory, and obtaining the value stored at that location is known as dereferencing the pointer. As an analogy, a page number in a book's index could be considered a pointer to the corresponding page; In C, array indexing is formally defined in terms of pointer arithmetic; that is, the language specification requires that  15 Aug 2015 Pointer arithmetic.
