In C++ , variables in the if clause are not initializing

I wanted am a beginner, and wrote this code as part of a project. Depending on the loanCode, I wanted to set different values to variables and print them out. However, The program is just ignoring the initializations in the "if" clauses. Anyone know what's wrong? Thanks!

#include <iostream>
#include <iomanip>
#include <cmath>

using namespace std;


int main()

{



cout << "This program can be used for new and existing loans!" << endl;


int loanLength;
int paymentPerYear;
double interestRate;
int maxAmount;
int minAmount;

string borrowerName;
cout << "Please enter the borrower's full name: " << endl;
getline (cin,borrowerName);

int loanCode;
cout << "Please enter a BRSL loan code: " << endl;
cin >> loanCode;


if (loanCode == 10)
{
    int loanLength = 30;         // (30-year plan)
    int paymentPerYear = 12;     // (12 payments per year)
    double interestRate = .038;  // (Interest Rate is 3.8%)
    int maxAmount = 425000;      // (Maximum amount is $425000)
    int minAmount = 5000;        // (Minimum amount is 5000)
    cout << "ok 10" << endl;
}

else if (loanCode == 20)
{
    int loanLength = 15;         // (15-year plan)
    int paymentPerYear = 12;     // (12 payments per year)
    double interestRate = .029;  // (Interest Rate is 2.9%)
    int maxAmount = 425000;      // (Maximum amount is $425000)
    int minAmount = 5000;        // (Minimum amount is 5000)
    cout << "ok 20" << endl;
}

else if (loanCode == 30)
{
    int loanLength = 5;          // (5-year plan)
    int paymentPerYear = 12;     // (12 payments per year)
    double interestRate = .026;  // (Interest Rate is 2.6%)
    int maxAmount = 100000;      // (Maximum amount is $100000)
    int minAmount = 5000;        // (Minimum amount is 5000)
    cout << "ok 30" << endl;
}

else if (loanCode == 40)
{
    int loanLength = 2;          // (2-year plan)
    int paymentPerYear = 12;     // (12 payments per year)
    double interestRate = .072;  // (Interest Rate is 7.2%)
    int maxAmount = 25000;       // (Maximum amount is $25000)
    int minAmount = 500;         // (Minimum amount is 500)
    cout << "ok 40" << endl;
}

else
{
    cout << "Loan code is not a valid value." << endl;
    cout << "Program will exit now" << endl;
    return 0;
}


cout << "your loan code is: " << loanCode << endl;
cout << "loanLength: "        << loanLength << endl;
cout << "paymentPerYear: "    << paymentPerYear << endl;
cout << "interestRate: "      << interestRate << endl;
cout << "maxAmout: "          << maxAmount << endl;
cout << "minAmount: "         << minAmount << endl;


return 0;
}

OUTPUT:

This program can be used for new and existing loans!

Please enter the borrower's full name:

Joe Shmoe

Please enter a BRSL loan code:

10

ok 10

your loan code is: 10

loanLength: 0

paymentPerYear: 0

interestRate: 0

maxAmout: 0

minAmount: 0

Program ended with exit code: 0
