  void my_sum(int);  
  int main()  
  {  
        int n;  
        clrscr();  
        printf("please enter a number : ");  
        scanf("%d",&n);  
        my_sum(n);  
        getch();  
        return 0;  
  }  
  void my_sum(int n)  
  {  
        int i,s=0;  
        for(i=1;i<=n;i++)  
        {  
              s+=i;  
        }  
        printf("Sum of first %d integer is %d\n",n,s);  
  }
