Week7

1. Week7
เปิดงานเดิมขึ้นมา

2. จากนั้นพิมพ์โค้ดเพิ่ม
#include "stdio.h"
void main()
{
char menu;
int counter;
for(counter=1;counter<=4;counter++)
{
printf("nPlease insert your order:");
scanf(" %c",&menu);
switch(menu)
{
case 'p' : printf("Papaya Saladn");
break;
case 't' : printf("Tomyam kungn");
break;
case 'i' : printf("Padthain");
break;
case 'l' : printf("Labmoon");
break;
defaul : printf("try again");
}
}
getch();
return 0;

3. ทาสูตรคูณ
#include "stdio.h"
void main()
{
int counter;
for(counter = 1;counter<=12;counter++)
{
printf("2 * %d = %dn",counter,counter*2);
}
printf("ngood bye");
getch();
return 0;
}

4. การใช้ While
#include "stdio.h"
void main()
{
int counter;
counter = 1;
while(counter<=12)
{
printf("2 * %d = %dn",counter,counter*2);
counter++;
}
printf("ngood bye");
getch();
return 0;
}

5. การใช้ do while
#include "stdio.h"
void main()
{
int counter;
counter =1;
do
{
printf("2* %d = %dn",counter,counter*2);
counter++;
}while(counter<=12);
printf("good bye");
getch();
return 0;
}

7. กาหนดแม่เอง
#include "stdio.h"
void main()
{
int counter,counter1,number;
for(counter1=1;counter1<=5;counter1++)
{
printf("please insert to number: ");
scanf("%d",&number);
for(counter=1;counter<=12;counter++)
{
printf("%d * %d = %dn",number,counter,number*counter);
}
}
printf("good byen");
getch();
return 0;
}

8. ทดสอบ
สร้างโปรแกรมนับเฉพาะเลขคู่ 2 4 6 8 10 โดยใช้ for
#include "stdio.h"
void main()
{
int counter,number;
for(counter=2;counter<=10;counter=counter+2)
{
printf("%dn",counter);
}
printf("ngood bye");
getch();
return 0;
}

9. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Array
#include "stdio.h"
void main()
{
int a[5];
a[0]=1;
a[1]=2;
a[2]=3;
a[3]=4;
a[4]=5;
printf("%d %d %d %d %d",a[0],a[1],a[2],a[3],a[4]);
getch();
return 0;
}

10. การเลือกแสดง
#include "stdio.h"
void main()
{
int a[5];
a[0]=1;
a[1]=2;
a[2]=3;
a[3]=4;
a[4]=5;
printf("%d %d ",a[2],a[4]);
getch();
return 0;
}

11. แยกชื่อ
#include "stdio.h"
void main()
{
char name[10];
printf("Please insert your name:");
scanf("%s",&name);
printf("You are spell %s n ");
printf("%c + %c + %c + %c + %c + %c + %c + %c + %c +
%c",name[0],name[1],name[2],name[3],name[4],name[5],name[6],name[7],name[8],name[9]);
getch();
return 0;
}

12. ตาราง
#include "stdio.h"
#include "conio.h"
void main()
{
int table[9][9],i,j,x;
for(i=1; i<=9; i++)
{
for (j=1; j<=9; j++)
{
x = i-1;
table[x][j-1]= i*j;
}
}
printf("* |t1t2t3t4t5t6t7t8t9n");

13. printf("----------------------------------------------------------------------------n");
for(i=0;i<9;i++)
{
printf("%d |t",i+1);
for (j=0;j<9; j++)
{
printf("%dt",table[i][j]);
}
}
getch();
return 0;
}
