Lets try one.

1. Write a program to add two no. 3 and 37.

The most basic of program is adding two no.'s when the no.'s are given.Here the numbers are 3 and 37. So, the result should show 40 as its answer. So, lets start...

#include<stdio.h>                          /*invoking first header file(compulsory)*/
#include<conio.h>                         /*invoking second header file(compulsory if you want to see the output)*/
main()                                                /*to write the logic of adding*/
{                                                        /*for the body of the logic of the main() function*/
int a=3,b=37,c;                                   /* or taking the variables and supplying some with given values*/
c=a+b;                                                /*for carrying out the sum*/
printf("The sum of 3 and 37 is: %d",c); /*for the printing of result*/
getch();                                                /*for getting the output to be displayed*/
}                                                          /*ending the epic addition procedure*/

This is just a small program of how to add two no. The basic step is here and gradually the level of programming gets tougher. The best and easiest way to understand a program is to understand the logic because most programs have common initial and final statements. The logic changes just!
