/*** These are the solutions to the C++ practicals given to us. Feel free to copy and run the code on your systems, but make
sure to choose different values as your input at runtime and if possible interchange the variable names.

Please if you notice any bugs or errors kindly let me know.

NB: Will try to finish up the remaining weeks ASAP.

Week 1 Solution
//Program to calculate 25% payrise of employees for 7 months
#include <iostream>
using namespace std;
int main ()
{
float asalary, msalary, bdpay, bdpay7;
float payrise = 0.25;

cout << "Enter your Total Salary for last year" << endl;
cin >> asalary;

msalary = asalary / 12;
cout << "Your monthly salary is: " << msalary << endl;

bdpay = msalary * payrise;
cout << "Your total 25% increase per month is: " << bdpay << "%" << endl;

bdpay7 = 7 * (msalary + bdpay);
cout << "Your total 25% increase for 7 months is: " << bdpay7 << "%" << endl;

return 0;
}


Week 2 Solution
//Program to Calculate Principal and Interest rate for three years
#include <iostream>
using namespace std;
int main()
{
    float principal, ainterest, interesty1, interesty2, interesty3;
    float arate = 0.1475;

    cout << "Enter the principal amount you invested: " << endl;
    cin >> principal;

    ainterest = principal * arate;
    cout << "Your Annual interset is: " << ainterest << endl;

    interesty1 = principal + ainterest;
    cout << "The Balance for Year 1 is: " << interesty1 << endl;

    interesty2 = interesty1 + ainterest;
    cout << "The Balance for Year 2 is: " << interesty2 << endl;

    interesty3 = interesty2 + ainterest;
    cout << "The Balance for Year 3 is: " << interesty3 << endl;

    cout << "The Amount Invested was: " << principal << endl;
    cout << "The Total Balance for Three Years is: " << interesty3 << endl;

    return 0;
}


Week 5 Solution

    cout << "Enter First Integer NUmber: ";
    cin >> a;
    cout << "Enter Second Integer NUmber: ";
    cin >> b;
    sum = a + b;
    product = a * b;
    cout << "The Sum of " << a << "+" << b << "=" << sum << endl;
    cout << "The Product " << a << "*" << b << "=" << product << endl;
