You can try by this…

for(i=o;i<=n;i+2)

{

s+=i;

}

//Or

for(i=o;i<=n;i++)

{

if(i%2==0)

{

s+=i;

}

}

It’s better if you can specify in which programming language you want the code to be written.  Each programming language has its own method of performing the operation but with the same logic. I’ll post a code in c#.

privateint GetSum()

    {

        int sum = 0;

        for (int i = 1; i <= 1000000; i++)

        {

            sum = sum + i;

        }

         returnsum;

    }

Above method will simply return the sum of the number from 1 to 1000000. In above code the basic programming application is the use of ForLoop. Any high level language will use a loop to perform the above operation.

Hello Mr. Amin,

Did you mean C programming? This is a powerful language of programming system. Every programming has it's own language. The C programming code for this function is given below:

#include<stdio.h>

#include<time.h>

int main(void)

{

tine t start, end;

double sum=0,i;

start = time(Null);

for(i=2;i<=1000000;i=i+2)

sum=sum+i;

end = time(NULL);

printf("Sum: %lf/n", sum);

printf("Calculating Time: %f seconds./n", diffitime(end, start));

return 0;

}

This is the main way of doing this function. By changing the limit of 'i', you can do other works like this one.

Hope now you can do this. Thank you for your question.
