Is there any way to speed up seperate graffics in a program?

[PyroPenguin]

Hello,
I have been teaching myself c++ for the last 2 weeks through various online tutorials. I always have liked programming and recently decided to teach myself some things of c++ because i will be taking a Programming 1 next semester at the college i attend. I'm basically just having fun writing code right now; not really into any major projects yet. Anyways this is what i would like to ask: is there any way to speed up certain vector graphics without speeding up the other?

here's my code:

void movement(){
     x_X=x;
     y_Y=y;
     if (key[KEY_UP]){
           if (y<100){
              ++y;
              }
           if (y>=100){
              --y;
              }
           }                
     if (key[KEY_DOWN]){
           if (y>300){
              --y;
              }
           if (y<=300){
              ++y; 
              }
           }
     if (key[KEY_RIGHT]){
           if (x<400){
              ++x;
              }
           if (x>=400){
              --x;
              }
           }
     if (key[KEY_LEFT]){
           if (x>=200){
              --x;
              }
           if (x<200){
              ++x;
              }
           }
           
     acquire_screen();  
     rectfill( buffer, x_X, y_Y, x_X-5, y_Y-5, makecol ( 0, 0, 0));
     rectfill( buffer, x, y, x-5, y-5, makecol ( 0, 255, 0));
     draw_sprite( screen, buffer, 0, 0);         
     release_screen();
     rest(20);

and i would like this set to move a little faster:

void enemy(){
     XkX = Xk;
     YkY = Yk;
     
     if (Xk == 200 && Yk == 100){
        direction = rand() %2+1;
        locator = 1;
        }
     if (Xk == 200 && Yk == 297){
        direction = rand() %2+1;
        locator = 2;
        }
     if (Xk == 395 && Yk == 100){
        direction = rand() %2+1;
        locator = 3;
        }
     if (Xk == 395 && Yk == 297){
        direction = rand() %2+1;
        locator = 4;
        }
     if (locator == 1 && direction == 1){
        ++Yk;
        }
     if (locator == 1 && direction == 2){
        ++Xk;
        }
     if (locator == 2 && direction == 1){
        --Yk;
        }
     if (locator == 2 && direction == 2){
        ++Xk;
        }
     if (locator == 3 && direction == 1){
        ++Yk;
        }
     if (locator == 3 && direction == 2){
        --Xk;
        }
     if (locator == 4 && direction == 1){
        --Yk;
        }
     if (locator == 4 && direction == 2){
        --Xk;
        }
     acquire_screen();
     circlefill ( buffer, XkX, YkY, 7, makecol( 0, 0, 0));
     circlefill ( buffer, Xk, Yk, 7, makecol( 128, 34, 200));
     draw_sprite( screen, buffer, 0, 0);
     release_screen();
     }

if i set rest(10) in the enemy section it speeds up movement too. Any help would be greatly appreciated!
