Question

Write a program to calculate and print the sum of odd numbers and the sum of even number for first 'n' natural number

Answer 1

Answer:

I hope u asked for c++ program if not mention the language

#include <iostream>

#include <conio.h>

using namespace std;

int main()

{

int i, num; //declare variables i, num

int oddSum=0,evenSum=0;

//declare and initialize variables oddSum,evenSum

cout<<"Enter the value of num \n";

cin>>num;

for(i=1; i<=num; i++){// for loop use to iterate 1 to num

if(i%2==0) //Check even number for sum

evenSum=evenSum+i;

else

oddSum=oddSum+i;

}

cout<<"Sum of all odd numbers are:"<< oddSum;

cout<<"\nSum of all even numbers are:"<<evenSum;

getch();

return 0;

}

Answer 2

Explanation:

#include<iostream.h>

#include<conio.h>

void main()

{

clrscr();

int n,s=0,m=0;

cout<<"Enter a number:";

cin>>n;

for(int i=1;i<=n;i++)

{

if(i%2= =0)

s=s+i;

else

m=m+i;

}

cout<<"Sum of even no."<<s<<endl;

cout<<"Sum of odd no."<<m;

getch();

}
