I'm suppose to create a program for a commercial bank.
The program should start with the following menu:
Press 1. To add new customer
2. To carry out a transaction
3. To exit
If the user selects 1 the program should ask for name, address, telephone number and the amount depositing.
If the user selects 2 he is given another menu.
Press 1. For Withdrawal
2.For Deposit
3. For Enquiry
If the user selects 1 which is withdrawal, he/she should ask the user for their customer no. and the amount to withdraw.
If the user select 2 which is deposit ask the user for customer
number and the amount to deposit.
If the user selects 3 ask for the customer number and print the customers balance.
After each transaction print the users balance.

This is what i have so far:

#include<stdio.h>
#include<string.h>
#include<stdlib.h>
 
int gun;
int cat;
int potion;
int hate;
int dagger;
int wow;
int token;
char name[100];
char address[100];
int tagger;
int myarray[7];
 
void menu_option() {
printf("\n Welcome to Saleem's Commercial Bank");
            printf("\n Press 1 if you are a new customer\n Press 2 if you want to carry out a transaction\n");
            printf("\n Press 3 to exit the system");
            printf("n\n Your choice->");
            scanf("%d",&dagger);
}
 
           void option_two(){
                switch(wow)
                     {
                      case 1: printf("\n Please enter your customer number");
                      scanf("%d",&potion);
                       printf("\n Please enter the amount you are withdrawing");
                      scanf("%d",&cat);
                            break;
                              
                case 2: printf("\n Please enter your customer number");
                              scanf("%d",&gun);
                              printf("\n Please enter the amount your depositing");
                              scanf("%d",&hate);
                              break;
                 
                default:("\n Please try again");
                    }
            }
            
   int main()
   {
       menu_option();
        struct customer_information
   {
       char name[100];
       char address[200];
       int token;
       
   };
    switch(dagger)
    {
       struct customer_information  person1;
       {
    case 1: printf("Please enter your name\n");
            scanf("%s",name);
 
            printf("Please enter your address\n");
            scanf("%s",&address);
 
            printf("Please enter your telephone number\n");
            scanf("%d",&token);
            
            printf("Please enter the amount your depositing\n");
            scanf("%d",&tagger);
             
            break;
       };
 
       case 2:  printf("\n Please select the suitable option");
                printf("\n Press 1 for withdrawal\n Press 2 for deposit\n");
                printf("\n Press 3 enquiry");
                printf("n\n Your choice->");
                scanf("%d",&wow);
                       break;
    
       case 3:printf("\n Thank You for using Saleem's Commercial Bank");
                            break;
   
       default: printf("\n The number you pressed is invalid. Please try again");
            menu_option();
    
    }
                   option_two();
 
    return 0;
   } 

I am having problems with assigning customer numbers and also
in printing the balances.
