In reality, there is no permanent love. As time passess your feelings to someones changes. As much as possible never give 100% love because if she/he doesn’t love you will not hurt too much. Like this quote - “A sad thing in life is that sometimes you meet someone who means a lot to you only to find out in the end that it was never bound to be and you just have to let go.”

We must learn to love, to be hurt and let go…

Input validation in turbo c is one of the problem by many programmers. If the input is not properly filtered by the program, it can ruined the entire program. Here is my sample program.

#include <math.h>
#include <stdio.h>
#include <conio.h>
#include <string.h>
#include <stdlib.h>

void main_menu(void);
void sub_menu(void);
void area_of_circle(void);
void area_of_triangle(void);
void area_of_square(void);
void input_validation(char tempo[6], int mem_pt);
void save_pt(int memo);

void save_pt(int memo)
{
switch (memo)
{
case 1: area_of_circle();
case 2: area_of_triangle();
case 3: area_of_square();
}
}

void input_validation(char tempo[6], int mem_pt)
{
int deci_ptr=0,i=0;
while (tempo[i]!=’\n’)
{
if (tempo[i]==’.'&&deci_ptr==1)
{
printf(”\nToo much decimal point!!!”);
getch();
save_pt(mem_pt);
}
if (tempo[i]<’0′||tempo[i]>’9′)
{
printf(”\nPlease enter a number!!!”);
getch();
save_pt(mem_pt);
}
if (strlen(tempo)==1&&tempo[i]==’.')
{
printf(”\nPlease enter a number!!!”);
getch();
save_pt(mem_pt);
}
if (tempo[i]==’.') deci_ptr=1;

i++;
}
}

void main_menu(void)
{
char c;
clrscr();
printf(”Main Menu:\n\n”);
printf(”[a] Area of Circle\n”);
printf(”[b] Area of Triangle\n”);

default: printf(”\nPlease select from the menu!”);getch();main_menu();
}
}

void sub_menu(void)
{

printf(”\n\nGoto Main Menu: [Y/N]: “);
c=getche();
switch (c)

}
}

void area_of_circle(void)
{
char number[6];
float area,radius;
clrscr();
printf(”Area of Circle:\n\n”);
printf(”Enter the radius of circle: “);
fgets(number,6,stdin);
input_validation(number,1);
radius=atof(number);
printf(”\nThe area of the circle is %f”,radius*radius*M_PI);
getch();
sub_menu();
}

void area_of_triangle(void)
{
char number[6];
float area,base,height;
clrscr();
printf(”Area of Triangle:\n\n”);
printf(”Enter base: “);
fgets(number,6,stdin);
input_validation(number,2);
base=atof(number);
printf(”\nEnter height: “);
fgets(number,6,stdin);
input_validation(number,2);
height=atof(number);
printf(”\nThe area of the triangle is %f”,base*height/2);
getch();
sub_menu();
}

void area_of_square(void)
{

Happy programming.

Another tourist spot destination in Singapore is the Marina Bay. You will see here famous spot which is the Merlion Park. Here are some of my photos.

One of the tourist spot in Singapore is Sentosa. There are lot of places to see in Sentosa like Universal Studios, Merlion Walk and the beaches. Here are my photos.

On my way to Sentosa, I just pass by to VivoCity and lucky to see Julian Beever doing his art work. Here are some of my photos.

These are my recent photos here in Singapore.

I learned a lot in studying autocad 2010 at Microcad. I learned how to create lines, circles, rectangle, polygons and many more. Positioning, editing and scaling the objects, I wish I can learn more about 3D objects and pass the final examination. ^_^

The Rubik Cube is one of my favorite toy. Invented by Ernő Rubik of Budapest, Hungary. Rubik cube comes in 2×2, 3×3, 4×4, 5×5, 6×6 and 7×7. For more information about this cube visit rubiks.

Solving the Rubik cube (3×3) is quite hard for first timer. To solve the cube easily you must first start to the bottom layer, then middle layer and lastly to the top layer. Check the youcandothecube for some information in solving the Rubik’s cube.

Merry Christmas and a Happy New Year!!!
