Last week I said that I will teach you How to use SSLAM in improving your coding/programming logic... Now here it is... 10 mins of reading can change your programming perspective...
first you have to download borland C++ to start... you can search it in google...
create a function name printLane(int x,int y); put your code in here...
Imagine this is your screen in console mode... the x (left to right) has a total of 79 characters and y (top to bottom) has 24 characters...
print a line on 0,0 (x,y)
printf("-------------------------------------------------------"); ( this is a line )
then type gotoxy(0,3) to go to the third line then print another line
printf("- - - - - - - - - - - - - -"); ( this is a line )
then type gotoxy(0,6) to go to the sixth line then print another line
printf("-------------------------------------------------------"); ( this is a line )
compile it then run it... you have to call it of course in console mode it should look like this...
--------------------------------------------------------------
- - - - - - - - - - - - - - - -
--------------------------------------------------------------
The code looks like this...
#include <stdio.h>
#include <conio.h>
void printLane(int x, int y){
clrscr();
gotoxy(x,y);
printf("-------------------------------------------------------");
gotoxy(x,y+3)
printf("- - - - - - - - - - - - - -");
gotoxy(x,y+6)
printf("-------------------------------------------------------");
}void main(){
printLane(0,0);
getch();
}Then create another function named printCar(int x, int y).. put your codes in here too...
how to draw a car... turbo c supports a variety of characters including special characters... just hold down the alt then press the numbers on numpads...
█ - full block character ( alt + 219 )
▄ - half lower block character ( alt + 220 )
0 - plain 0 or if you like you can use other special character which is the bullet
▄███▄ = SIMPLE CAR ^___^
0 0
print the car on the middle of the broken line and the lower line...
--------------------------------------------------------------
- - - - - - - - - - - - - - - -
▄███▄ print the car here...
0 0--------------------------------------------------------------
the code now should look like this
#include <stdio.h>
#include <conio.h>
void printLane(int x, int y){
clrscr();
gotoxy(x,y);
printf("-------------------------------------------------------");
gotoxy(x,y+3)
printf("- - - - - - - - - - - - - -");
gotoxy(x,y+6)
printf("-------------------------------------------------------");
}
printCar(int x, int y){
gotoxy(x,y+4);
printf("▄███▄");
gotoxy(x,y+5);
printf(" 0 0 ");
}
void main(){
printLane(0,0);
printCar(0,0);
getch();
}The Question is... HOW WILL WE MOVE THE CAR? Lets focus now on the main method...
!kbhit() - means "stop if user pressed a key..." put it in a while loop then it reads... while not keyboard hit!! make sense?
void main(){
int x=0;
while ( !kbhit() ){
delay(100);
printLane(0,0);
printCar(x,0);
x++;
if( x== 79) x=0;
}
}
see how it goes...
HERE IS THE SIMPLE LOGIC...
Clear the Screen
Print the Lane
Print The Car on x,0
increment x
if x==79 reset the value of x;
do it all over again...
IF you look at it clearly... we have 2 objects here... the lane and the car... but the car has a function move The Whole code should look like this...
#include <stdio.h>
#include <conio.h>
#include <dos.h>
void printLane(int x, int y){
clrscr();
gotoxy(x,y);
printf("-------------------------------------------------------");
gotoxy(x,y+3)
printf("- - - - - - - - - - - - - -");
gotoxy(x,y+6)
printf("-------------------------------------------------------");
}
printCar(int x, int y){
gotoxy(x,y+4);
printf("▄███▄");
gotoxy(x,y+5);
printf(" 0 0 ");
}
void main(){
int x=0;
while ( !kbhit() ){
delay(100);
printLane(0,0);
printCar(x,0);
x++;
if( x== 79) x=0;
}
}
