Approach for the program
The initial frame displays the app's name and developer details, created using printf statements and a system-supplied function . In the C/C++ standard library, the system function is available for executing commands that the OS command processor or terminal can run, providing the result once the command completes. By using System("Color 3F"), the console's background color (3) and text color (F) can be modified. When System("pause") is called, a prompt "Press any key to continue" will appear, pausing the screen. Utilizing the gotoxy function to set the data presentation coordinates can be advantageous.
Program Breakdown
Example
struct emp {
char name [ 50 ] ;
float salary ;
int age ;
int id ;
} ;
The code mentioned above will be utilized to define the layout of an employee within the system.
Example
void gotoxy ( int x , int y )
{
cord.X = x ;
cord.Y = y ;
SetConsoleCursorPosition (
GetStdHandle ( STD_OUTPUT_HANDLE ) ,
cord ) ;
}
FILE * fp , * ft ;
The code snippet above is responsible for defining the position of the cursor in the console.
Example
void addrecord ( )
{
system ( " cls " ) ;
fseek ( fp , 0 , SEEK_END ) ;
char another = ' y ' ;
while ( another = = ' y ' ) {
printf ( " \ n Enter Name : " ) ;
scanf ( " % s " , e.name ) ;
printf ( " \ nEnter Age : " ) ;
scanf ( " % d " , & e.age ) ;
printf ( " \ n Enter Salary : " ) ;
scanf ( " % f " , & e.salary ) ;
printf ( " \ n Enter EMP-ID : " ) ;
scanf ( " % d " , & e.id ) ;
fwrite ( & e , size , 1 , fp ) ;
printf ( " \ n Want to add another "
" record ( Y / N ) : " ) ;
fflush ( stdin ) ;
scanf ( " % c " , & another ) ;
}
}
The above code will use to add the record.
Example
void deleterecord ( )
{
system ( " cls " ) ;
char empname [ 50 ] ;
char another = ' y ' ;
while ( another = = ' y ' ) {
printf ( " \ n Enter employee "
" name to delete : " ) ;
scanf ( " % s " , empname ) ;
ft = fopen ( " temp.txt " , " wb " ) ;
rewind ( fp ) ;
while ( fread ( & e , size ,
1 , fp )
= = 1 ) {
if ( strcmp ( e.name ,
empname )
! = 0 )
fwrite ( & e , size , 1 , ft ) ;
}
fclose ( fp ) ;
fclose ( ft ) ;
remove ( " data.txt " ) ;
rename ( " temp.txt " , " data.txt " ) ;
fp = fopen ( " data.txt " , " rb + " ) ;
printf ( " \ n Want to delete another "
" record ( Y / N ) : " ) ;
fflush ( stdin ) ;
another = getche ( ) ;
}
}
The code snippet mentioned earlier is employed to remove a data entry from the system.
Example
void displayrecord ( )
{
system ( " cls " ) ;
// sets pointer to start
// of the file
rewind ( fp ) ;
printf ( " \ n = = = = = = = = = = = = = = = = = = = = = = = = = "
" = = = = = = = = = = = = = = = = = = = = = = = = = = = "
" = = = = = = " ) ;
printf ( " \ n NAME \ t \ t AGE \ t \ t SALARY\ t \ t "
" \ t I D \ n " ,
e.name , e.age ,
e.salary , e.id ) ;
printf ( " = = = = = = = = = = = = = = = = = = = = = = = = = = = "
" = = = = = = = = = = = = = = = = = = = = = = = = = = = "
" = = = = \ n " ) ;
while ( fread ( & e , size , 1 , fp ) = = 1 )
printf ( " \ n % s \ t \ t % d \ t \ t%.2f \ t % 10d " ,
e.name , e.age , e.salary , e.id ) ;
printf ( " \ n \ n \ n \ t " ) ;
system ( " pause " ) ;
}
The above code will use to display records.
Example
void modifyrecord ( )
{
system ( " cls " ) ;
char empname [ 50 ] ;
char another = ' y ' ;
while ( another = = ' y ' ) {
printf ( " \ n Enter employee name "
" to modify : " ) ;
scanf ( " % s " , empname ) ;
rewind ( fp ) ;
// While File is open
while ( fread ( & e , size , 1 , fp ) = = 1 ) {
// Compare the employee name
// with ename
if ( strcmp ( e.name , empname ) = = 0 ) {
printf ( " \ n Enter new name : " ) ;
scanf ( " % s " , e.name ) ;
printf ( " \ n Enter new age : " ) ;
scanf ( " % d " , & e.age ) ;
printf ( " \ n Enter new salary : " ) ;
scanf ( " % f " , & e.salary ) ;
printf ( " \ n Enter new EMP-ID : " ) ;
scanf ( " % d " , & e.id ) ;
fseek ( fp , -size , SEEK_CUR ) ;
fwrite ( & e , size , 1 , fp ) ;
break ;
}
}
// Ask for modifying another record
printf ( " \ n Want to modify another "
" record ( Y / N ) : " ) ;
fflush ( stdin ) ;
scanf ( " % c " , & another ) ;
}
}
The code snippet above is utilized to update the current record within the system.
