/In the very first step of program,the library will be included which will contain necessary information of commands i used in the program./
#include<stdio.h>
/second step is the declaration ,that main function of the program is integer type function/
int main()
/the program is written in the middle brackets{}/
{
/it is the declaration that variables are of which type/
float a,b,p,q; int m,c,s,d,w,x;

/by this printf command user will be able to know that he has to enter input here/

/in the following steps the validity of inputs will be checked/ /*in this first step program will check that either inputs are integers or not */
