Features of Student Record System in C:
Simple functions have been to manipulate data structure and file handling, so here I will just list the features of this project.
- Add student record
- Search student record
- Modify student record
- Generate marksheet
- Delete student record
- Change password
The functions listed below have been used to produce background with color effects. They are described in the source code with comments.
- void SetColor(int ForgC)
- void ClearConsoleToColors(int ForgC, int BackC)
- void SetColorAndBackground(int ForgC, int BackC
void gotoxy (int x, int y) – I have been describing this function in most of the C projects published on this site. You need to understand this function as it is an important one used in this mini project on student record management system.
This function allows you to print text in any place of screen. Using this function in Code::Blocks requires coding, but it can be directly used in Turbo C. Here is a code for this function in Code::Blocks.
CODE:
#include <stdio.h>
#include <string.h>
#include <conio.h>
#include <stdlib.h>
#include <windows.h>
struct student{
char ID[15];
char name[20];
char add[20];
char parname[20];
int Class;
long unsigned int phone_no;
};
struct student stu;
///This will set the forground color for printing in a console window.
void SetColor(int ForgC)
{
WORD wColor;
///We will need this handle to get the current background attribute
HANDLE hStdOut = GetStdHandle(STD_OUTPUT_HANDLE);
CONSOLE_SCREEN_BUFFER_INFO csbi;
///We use csbi for the wAttributes word.
if(GetConsoleScreenBufferInfo(hStdOut, &csbi))
{
///Mask out all but the background attribute, and add in the forgournd color
wColor = (csbi.wAttributes & 0xF0) + (ForgC & 0x0F);
SetConsoleTextAttribute(hStdOut, wColor);
}
return;
}
void ClearConsoleToColors(int ForgC, int BackC)
{
WORD wColor = ((BackC & 0x0F) << 4) + (ForgC & 0x0F);
///Get the handle to the current output buffer...
HANDLE hStdOut = GetStdHandle(STD_OUTPUT_HANDLE);
///This is used to reset the carat/cursor to the top left.
COORD coord = {0, 0};
///A return value... indicating how many chars were written
/// not used but we need to capture this since it will be
/// written anyway (passing NULL causes an access violation).
DWORD count;
///This is a structure containing all of the console info
/// it is used here to find the size of the console.
CONSOLE_SCREEN_BUFFER_INFO csbi;
///Here we will set the current color
SetConsoleTextAttribute(hStdOut, wColor);
if(GetConsoleScreenBufferInfo(hStdOut, &csbi))
{
///This fills the buffer with a given character (in this case 32=space).
FillConsoleOutputCharacter(hStdOut, (TCHAR) 32, csbi.dwSize.X * csbi.dwSize.Y, coord, &count);
FillConsoleOutputAttribute(hStdOut, csbi.wAttributes, csbi.dwSize.X * csbi.dwSize.Y, coord, &count );
///This will set our cursor position for the next print statement.
SetConsoleCursorPosition(hStdOut, coord);
}
return;
}
