    Need Urgent Help!!!

    Im about to present this program in a few hours but my brain is only capable of this. Need your help friends.

    The program is a record system that allows the user to input the details of employees their name, position and salary. The program needs to have and add, search, sort and delete and should have 3 structures. Im just a beginner i need all the help i can get.

    Code:
    #include<stdio.h>#include <stdlib.h>
    #include <string.h>
    #include <windows.h>
    #define size 50
    
    
    typedef struct {
    	char fullname[30];
    	char lname[30];
    	char position[20];
    	char id[3];
    	float salary;
    }employee;
    
    
    void menu(){
    	printf("\n\t\n\tM E N U");
    	printf("\n\n[1] Add New Employee");
    	printf("\n[2] Increase Salary of an Employee");
    	printf("\n[3] Decrease Salary of an Employee");
    	printf("\n[4] Display an Employee Info");
    	printf("\n[5] Display All Employee");
    	printf("\n[0] Exit");
    }
    
    
    void displayone(employee e[],int max){
    	char search1[size];
    	int i;
    	system("cls");
    	
    	do{
    		printf("\nInput Employee ID#: ");
    		gets(search1);
    		fflush(stdin);
    		for(i=0;i<size;i++){
    			if(strcmpi(search1,e[i].id)==0){
    				printf("\nID: %s", e[i].id);
    				printf("\nFullname: %s",e[i].fullname);
    				printf("\nPosition: %s", e[i].position);
    				printf("\nSalary: %.2f", e[i].salary);
    				getch();
    				return;
    			}
    		}
    		printf("\nRecord not Found");
    	}while(1);
    }

    So what seems to be the problem?

    Edit: Also you should never, Never, NEVER use gets(). This function is so unsafe that it has been removed from the current C standard.

    Two other problems in addition to @jimblumberg's comments.

    fflush(stdin) should NEVER be used! fflush() is for output file only! fflush(stdin) is a perfect example of Undefined Behavior!

    Your code formatting should be cleaned up. Please see the Wikipedia article that lists several different formatting styles. Choose one and please be consistent.

    Code:
    case 4:         system("cls");
                            displayone(e,max);
                            system("cls");
                            break;
                 
            case 5:         system("cls");
                            displayAll(e,max);
                            system("cls");
                            break;
    What's the point of displaying the details only to immediately clear them from the screen before the user even has the chance to read them?

    Please, stop using system() in your code...

    1. "cls" is available in Windows/DOS only;
    2. it isn't safe... What if you have an "CLS.COM or CLS.EXE" in your PATH?
    3. It is SLOW!

    Here's a better routine to clear your screen in a terminal:

    Code:
    #if defined(__WINNT)
    #include <windows.h>
      
    /* Uses Win32 Console API */
    void clearscreen(void)
    {
      HANDLE hConsole;
      COORD coord = {0, 0};
      CONSOLE_SCREEN_BUFFER_INFO csbi;
      DWORD dwConsoleSize, dwWriten;
      
      hConsole = GetStdHandle(STD_OUTPUT_HANDLE);
      GetConsoleScreenBufferInfo(hConsole, &csbi);
      dwConsoleSize = csbi.dwSize.X * csbi.dwSize.Y;
      
      FillConsoleOutputCharacter(hConsole, (TCHAR)' ', 
                                 dwConsoleSize, coord, &dwWriten);
      FillConsoleOutputAttribute(hConsole, csbi.wAttributes, 
                                 dwConsoleSize, coord, &dwWriten);
      
      SetConsoleCursorPosition(hConsole, coord);
    }
    #else
    #include <stdio.h>
      
    /* Uses ANSI -- almost all Unix terminals supports it. */
    void clearscreen(void) { fputs("\x1b[2J", stdout); }
    #endif
