In 3^rd step we write algorithm to solve our problem algorithm is solution of problem in simple high-level language (English) we write algorithm for flexibility by using this algorithm we can write program code in any required Programming language. <span style="mso-spacerun: yes;"> </span></div> <div class="MsoNormal" style="text-align: justify;">                                             In 4^th step we design graphical structure of our program in same flow as it gonna be happen in our compiler we use specific fingers for specific step. In 5^th step we write actual code of our program by using design algorithm and specific programming language here we are going to discus according to C++ , We firstly include header file in our program by using #include Keyword then active std function by writing “ using namespace std “ our cout cin are belongs to std then we move to our main function this is <span style="mso-spacerun: yes;"> </span>also the entry point for our program control .
