Is there a easy way to insert header files on the C code (without using include)?

[Aguiar-Gabriel]

I was coding for a college project, and it is practically finished. But my amazing teacher placed the condition that it would only be possible to send 1 .c file, and i have one header that i used to organize some functions of the code. I am having a lot of trouble making this in one file. Here is the code:

#include <string.h> //Defining one variable type, macro, and various functions for manipulating arrays of characters.
#include "221037581.h" //Defining my own header to import especif functions.
#include <stdlib.h> //Defining the standart library.

#define REG_USI 1 //Register plant
#define REG_CONS 2 //Register consumer
#define REG_CONT 3 //Register contract
#define CHECK_USI 4 //Check plant
#define CHECK_CONS 5 //Check consumer
#define DEL_USI 6 //Delete plant
#define DEL_CONS 7 //Delete consumer
#define EXIT 8 //Exit

#define SIZ_NAME 100 //Defining maximum name size
#define CPF_MIN 11 //Defining cpf size
#define SIZ_ID 18 //Defining id size
#define MAX_SIZE 100 //Defining maximum size for database
#define SIZ_DATE 8 //Defining date size
#define SIZ_CNPJ 14 //Defining cnpj size

#define DB_NAME 'n' //Defining name database
#define DB_ID 'i' //Defining ID database
#define DB_USER 'u' //Defining user database
#define DB_plant 'p' //Defining plant database
#define DB_CONTRACT 'c' //Defining contract database

int main_menu();  //Defining menu function 
void r_u(); //Defining register plant function
void r_c(); //Defining register consumer function
void r_contrat(); //Defining register contract function
void c_u(); //Defining check plant function
void c_c(); //Defining check consumer function
void d_u(); //Defining delete plant function
void d_c(); //Defining delete consumer function

void info_plant(char id[SIZ_ID]); //Defining function to consult the plant and show how much MWs still is usable.
void info_user(char id[SIZ_ID]); //Defining function to consult user and your contracts

int main() //Main function
{
    int n; 

    FILE *data_base;

    data_base = fopen(DATABASE_PP, "r"); //Opening database
    if (data_base == NULL) {
      data_base = fopen(DATABASE_PP, "w+");
      fprintf(data_base,"0xxxxxxxxxxxxx\nName :3\nxxxxxxxx\n1.000000\n");
    }
