Program Sum Of First N Odd Natural Number

Sum of first N even natural number program in C

This is our first program in C programming language. This C program will print the text

“Hello World!” on the console output screen. In this post we will learn how to 

write a C Program and explore each statements in this C Program and many more.

  */
  #include<stdio.h>
  int main()
   {
        int oddsum=0, i=1, num, tovalue;

         printf("Enter value for N: ");
           scanf("%d",&num);
           tovalue=num*2;

         }      
         printf("Sum of  %d odd No is %d: ",num,oddsum);
          return(0);
   } 
 

Output :

  Enter value for N: 3
  Sum of 5 odd No is: 9

Explanation Of Each Statements In The Program:-

To learn any programming language, practical is must important than others factors. First of

all we learn and understand the language and then we implements, each things related to 

the language and explore about it. After all we are interested in making products (Software)

by using that language.
