Ive been trying to learn the problem for awhile here's my code 

#include  #include    using namespace std;   const int MAX_TRANSACTIONS = 100;   struct Transaction {    char type;  // 'd' for debit, 'c' for credit, 'b' for balance    string date;    double value; };   int daysInMonth(int month, int year) {    if (month == 2) {        if ((year % 400 == 0) || ((year % 100 != 0) && (year % 4 == 0)))            return 29; // Leap year        else            return 28;    } else if (month == 4 || month == 6 || month == 9 || month == 11) {        return 30;    } else {        return 31;    } }   int main() {    Transaction transactions[MAX_TRANSACTIONS];    int numTransactions = 0;     // Read the initial balance    double balance;    cin >> transactions[0].date >> balance;    transactions[0].type = 'b';  // 'b' for balance     int startDay, startMonth, startYear;    sscanf(transactions[0].date.c_str(), "%d/%d/%d", &startMonth, &startDay, &startYear);     int currentDay = startDay;    int currentMonth = startMonth;    int currentYear = startYear;     // Read transactions until 'q' or more than 30 days    while (true) {        // Handle overdraft before checking transaction order        if (transactions[numTransactions].type == 'd' && balance > transactions[numTransactions + 1].type;        if (transactions[numTransactions + 1].type == 'q') break;         cin >> transactions[numTransactions + 1].date >> transactions[numTransactions + 1].value;         int transactionDay, transactionMonth, transactionYear;        sscanf(transactions[numTransactions + 1].date.c_str(), "%d/%d/%d",               &transactionMonth, &transactionDay, &transactionYear);         if (transactionYear = 30) {            break;        }    }     // Calculate and print average balance    double averageBalance = balance / (numTransactions + 1);    cout 

when ran with the input it outputs 

the actual output is suppose to be 

Can someone please help I have been working on this all day. The code is suppose to stop after 30 days and then take the average but rightnow its not getting passed the first set of days.
