for(counter=1;counter<=12;counter++)
{
printf("2 x%d=%d",counter,counter*2);
}
printf("ngoodbye");
getch();
return0;
}

6. Loop While
#include <stdio.h>
void main()
{
int counter;
counter=1;
while (counter<=12)
{
printf("2 x%d=%dn",counter,counter*2);
counter++;
}
printf("ngoodbye");

7. getch();
return 0;
}

8. Do while
#include <stdio.h>
void main()

9. {
int counter;
counter=1;
do
{
printf("2 x%d=%dn",counter,counter*2);
counter++;
}while (counter<=12);
printf("goodbye");
getch();
return 0;
}

10. ลูกค้าทาการกรอกค่าเอง

for(counter1=1;counter1<=5;counter1++)
{
printf("please insert to number:");
scanf("%d",&number);
for(counter=1;counter<=24;counter++)
{
printf("%dx%d=%dn",number,counter,number*counter);
}

12. }
