Program to Print the Value from 1 to 10, and Display the Addition of Odd & Even Numbers
Write a program to print the value from 1 to 10, and display addition of odd numbers & even numbers?

Answer 1

first start with preprocessor directive
//program for printing 1 to 10 numbers as well as even sum and odd sum
#include<stdio.h>
void main()
{
        int i,n,evensum=0,oddsum=0;
        clrscr();                                          /*clears the screen*/
      for(i=1;i<=10;i++)
      {
         printf("%d\n",i);                        /*prints 1 to 10 numbers*/
           if(i%2==0)                             /*condition to check even*/
           {
               evensum=(evensum+i);   /*even numbers are added here                         }                                                 and kept in the variable evensum*/
          else
            {
               oddsum=(oddsum+i);      /*odd numbers are added here and kept              }                                                      in the variable oddsum*/
        }                                             /*end of for loop used for repetition*/
   printf("even numbers sum in 1 to 10 is%d\n",evensum);  
   printf("odd numbers sum in 1 to 10 is %d",oddsum);
   getch();                                     /*shows the output*/
}
output of the above program is 
1
2
3
4
5
6
7
8

10
even numbers sum in 1 to 10 is 30
odd numbers sum in 1 to 10 is 25
