The mini-project “Student Record System Project in C” is a console application using the C programming language. This project compiled in Code Blocks with the GCC compiler. In this console application, you can do basic Student Record tasks like adding the student info, view the added student, search the students, ..etc.
This application based on file handling in C, where I have used a file-related function like fopen, fread, fwrite, ..etc. Good thing is that “Student Record System Project” is password-protected, so only authorized persons able to login to this application.
Also to increase the readability, I have broken the application in different functions. Each function of the project extensively use in the 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.
List of a function used in “Student Record 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\n";
const char defaultPassword[] ="aticleworld\n";
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############ Student Record Management System Project 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 “Student Record 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\n\n\t\t\t Enter any key to continue.....");
getch();
}
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;
}
isValidDate():
This function read the date in the format of dd/mm/yyyy also it validates the entered date.
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;
}

deleteStudent():
This function asks the student id from the user for the student to want to delete. In this function, I am creating a temporary binary file and copy all the data from the existing file except the book whose student id entered by the user. In the last renamed the temporary bin file with an existing binary file.
