Vectors are sequence container (same as dynamic arrays) which resizes itself automatically. The size changes (i.e. vector can shrink or expand as needed at run time) when an element is inserted or deleted, with their storage being handled automatically by the container. Just like arrays, vector elements are placed in adjacent memory locations so that they can be accessed and traversed using iterators i.e. subscript operator .
This is a list of 10 most prestigious and old programming contests and challenges which you can participate and win prizes. Most of them are annual competitions but few are continuous and you can enter at any time. You can use C, C++, Java or C# .NET or any other programming language in these contests.
This program will solve quadratic equations. It accepts coefficients of a quadratic equation from the user i.e. a, b and c and displays the roots. To compile the program name it quadratic_solver.cpp then type g++ -o quadratic_solver quadratic_solver.cpp You may need to use math.h like this: #include if you are using windows C++ programming software. (I tried it without the math.h and got an “undeclared identifier” error)
This article is about a collection of common Computer Science algorithms which may be used in C projects. The C Programming Language has a much smaller Standard Library as compared to other more modern programming languages such as Java or Python. The library provides a basic set of mathematical functions, string manipulation, type conversions, and file and console-based I/O.
