The mini-project “Train Ticket Booking System Project” is a console application using the C programming language. This project compiles in Code Blocks with the GCC compiler. In this console application, you can do basic passenger record tasks like adding the passenger info, view the added passenger, search the passenger, ..etc.
This application is based on file handling in C, where I have used a file-related function like fopen, fread, fwrite, ..etc. Good thing is that the “Train Ticket Booking System Project” is password-protected, so only authorized persons are able to log in to this application.
Also to increase the readability, I have broken the application into different functions. Each function of the project extensively uses file handing function, so it is also a great project to understand file handling in C.
Note: Don’t copy and paste the code for your project. Use the code to learn and do the project yourself.
Functions used in “Train Ticket Booking System Project in C”:
isFileExists():
This function verifies that a file has been created or not. If the file exists, the function return 1 otherwise returns 0.
int isFileExists(const char *path)
{
// Try to open file
FILE *fp = fopen(path, "rb");
int status = 0;
// If file does not exists
if (fp != NULL)
{
status = 1;
// File exists hence close file
fclose(fp);
}
return status;
}
init():
This function creates the file if not exist and copies the default password (“aticleworld”) in file header structure.
void init()
{
FILE *fp = NULL;
int status = 0;
const char defaultUsername[] ="aticleworld";
const char defaultPassword[] ="aticleworld";
sFileHeader fileHeaderInfo = {0};
status = isFileExists(FILE_NAME);
if(!status)
{
//create the binary file
fp = fopen(FILE_NAME,"wb");
if(fp != NULL)
{
//Copy default password
strncpy(fileHeaderInfo.password,defaultPassword,sizeof(defaultPassword));
strncpy(fileHeaderInfo.username,defaultUsername,sizeof(defaultUsername));
fwrite(&fileHeaderInfo,FILE_HEADER_SIZE, 1, fp);
fclose(fp);
}
}
}
printMessageCenter():
This function prints the message in the middle of the head massage. I have passed the message in this function as per the operation.
void printMessageCenter(const char* message)
{
int len =0;
int pos = 0;
//calculate how many space need to print
len = (78 - strlen(message))/2;
printf("\t\t\t");
for(pos =0 ; pos < len ; pos++)
{
//print space
printf(" ");
}
//print message
printf("%s",message);
}
headMessage():
It prints the message on the top of the console and prints the message as per operation.
void headMessage(const char *message)
{
system("cls");
printf("\t\t\t###########################################################################");
printf("\n\t\t\t############ ############");
printf("\n\t\t\t############ Train Ticket Booking System in C ############");
printf("\n\t\t\t############ ############");
printf("\n\t\t\t###########################################################################");
printf("\n\t\t\t---------------------------------------------------------------------------\n");
printMessageCenter(message);
printf("\n\t\t\t----------------------------------------------------------------------------");
}
welcomeMessage():
This function displays the first welcomes screen of the “Train Ticket Booking System Project in C” and asks the user to press any key to access the library application.
void welcomeMessage()
{
headMessage("www.aticleworld.com");
printf("\n\n\n\n\n");
printf("\n\t\t\t **-**-**-**-**-**-**-**-**-**-**-**-**-**-**-**-**-**-**\n");
printf("\n\t\t\t =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=");

printf("\n\t\t\t = Train Ticket =");
printf("\n\t\t\t = Booking SYSTEM =");
printf("\n\t\t\t = =");
printf("\n\t\t\t =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=");
printf("\n\t\t\t **-**-**-**-**-**-**-**-**-**-**-**-**-**-**-**-**-**-**\n");
printf("\n\n\n\t\t\t Enter any key to continue.....");
getchar();
}
isNameValid():
It validates the user name, author name ..etc. I have permitted this function to take the space in names.
int isNameValid(const char *name)
{
int validName = 1;
int len = 0;
int index = 0;
len = strlen(name);
for(index =0; index <len ; ++index)
{
if(!(isalpha(name[index])) && (name[index] != '\n') && (name[index] != ' '))
{
validName = 0;
break;
}
}
return validName;
}
isValidMobNumber()
it allowed only digits for the mobile number.
int isValidMobNumber(const char *name)
{
int validName = 1;
int len = 0;
int index = 0;
len = strlen(name);
for(index =0; index <len ; ++index)
{
if(!(isdigit(name[index])) && (name[index] != '\n') && (name[index] != ' '))
{
validName = 0;
break;
}
}
return validName;
}
isValidDate():
This function reads the date in the format of dd/mm/yyyy also validates the entered date.
int IsLeapYear(int year)
{
return (((year % 4 == 0) &&
(year % 100 != 0)) ||
(year % 400 == 0));
}
// returns 1 if given date is valid.
int isValidDate(Date *validDate)
{
//check range of year,month and day
if (validDate->yyyy > MAX_YR ||
validDate->yyyy < MIN_YR)
return 0;
if (validDate->mm < 1 || validDate->mm > 12)
return 0;
if (validDate->dd < 1 || validDate->dd > 31)
return 0;
//Handle feb days in leap year
if (validDate->mm == 2)
{
if (IsLeapYear(validDate->yyyy))
return (validDate->dd <= 29);
else
return (validDate->dd <= 28);
}
//handle months which has only 30 days
if (validDate->mm == 4 || validDate->mm == 6 ||
validDate->mm == 9 || validDate->mm == 11)
return (validDate->dd <= 30);
return 1;
}
menu():
This function displays the library menu and asks the user to select the option. If the user selects 0, then the application will close.
void menu()
{
int choice = 0;
do
{
headMessage("MAIN MENU");
printf("\n\n\n\t\t\t1.Add New passenger Record");
