Develop a function to calculate sum of n even integers starting from a given even integer.

#include <stdio.h>
#include <conio.h>
void main ( )
{                        
        int     s, n, t;
        clrscr ( );
      
        do
        {                          
                    printf("\n\n\n\t Enter an even integer to start with..:"); scanf("%d",&s);
        }while ( s % 2 != 0 );
                  
        printf("\n\t Enter the number of even integers..:"); scanf("%d",&n);
        t = sumeven ( s, n );
        printf("\n\n\n\t Starting from %d sum of %d even integers = %d",s,n,t);
        getch ( );
}              
                      
int sumeven ( int    s, int    n )
{                           
        int     i, t = 0;
        for ( i = 1; i <= n; i++, s = s+2 )
        {                                     
                    t = t + s;
        }
        return t;
}
