C Program: Calculate the Sum of all Odd numbers between 1 to 50 by using do-while Statement

Statement of C program: Prints the Sum of all Odd integers between 1 to 50 :

#include<stdio.h>

#include<conio.h>

void main()

{

int odnum , sum=0;                                 // odnum Stands for Odd Number

odnum=1;


clrscr();

do

{

sum=sum+odnum;                              // It is also written as sum+=odnum

odnum=odnum+2;                              // It is also written as odnum+=2

}while(odnum<=50);

printf(" Sum=%d\n" , sum);

}                                                    /* End of main() */

                                                 

Output:

 Sum=625
