Hi guys I'm developing a mini game as a project, and I would gladly appreciate if someone could tell me if I'm heading in the right direction.

The aim is to develop a bee-keeping game. First of all I need to have a text file called Inventory which contains the following data:

Total Amount of Bees: 15
Total Amount of Infected Bees: 5
Total Amount of Money: 1500
Total Amount of Honey Jars: 5
Total Amount of Beeswax: 0

Once that is finished I need to write a menu which holds the following choices:
New Game (Set to Default Amounts)
Buy New Bees
Bees Death Process
End Program

Below is the code I have written so far

Code:
#include <stdio.h>


struct Inventory {
int NoOfBees, NoOfInfBees, Money, Honey, Beeswax;
};


    int enterChoice(void);
    void textFile(FILE *readPtr);
    void BuyBees(FILE *fPtr);
    void DeadBees(FILE *fPtr);


int main(void)
{
    FILE *cfPtr;
    int choice;


    if ((cfPtr = fopen("Inventory1.txt", "rb+"))==NULL){
    printf("File could not be opened.\n");
    }
    else {
        while((choice=enterChoice())!=4){
        switch(choice){


        case 1:
        textFile(cfPtr);
        break;


        case 2:
        BuyBees(cfPtr);
        break;


        case 3:
        DeadBees(cfPtr);
        break;


        default:
        printf("Invalid choice.\n");
        break;
        }
    }
    fclose(cfPtr);
    }
    return 0;
}
    /*New Game (Default Amounts, Choice 1)*/
    void textFile(FILE*readPtr)
    {
    FILE *writePtr;
    struct clientData client = {0,"","",0.0};
    if ((writePtr = fopen("Inventory1.txt","w"))==NULL){
    printf("File could not be opened.\n");
    }
    else {
    rewind(readPtr);
    fprintf(writePtr,"Total Number of Bees: 15\n", "Total Number of Infected Bees: 5\n", "Total Amount of Money: 1500\n", "Total Amount of Honey Jars: 5\n", "Total Amount of Beeswax: 0\n");


    while (!feof(readPtr)) {
    fread(&client, sizeof(struct clientData),1,readPtr);
    }
}
    fclose(writePtr);
    }
}


    /*Menu*/
    int enterChoice( void )
    {
    int menuChoice;


    printf( "\nEnter your choice\n"
    "1: New Game (Set to Default Amounts)\n"
    "2: Buy Bees.\n"
    "3: Bees Death Process.\n"
    "4: End Program.\n");


    scanf("%d", &menuChoice);
    return menuChoice;
}
Any help/tips/critique would be greatly appreciated.
