    	double loan_amount;
    	int term_of_loan;
    	int cust_status;
    public:
    	
    	BankLoanApproval (int r, double y, double la, int t, int cs); 
    	int GetRecords() {return records;}
    	double GetIncome() {return yr_income;}
    	double GetLoanAmount() {return loan_amount;}
    	int GetTerm() {return term_of_loan;}

    Change
    BankLoanApproval (int r, double y, double la, int t, int cs);
    to
    BankLoanApproval (int r, double y, double la, int t, int cs) {};
    and I suggest you remove the argument list if you're not going to do anything with the variables passed. That, or you could assign the arguments to your member variables.
