    03.11. Loan Interest Rate

    -------------------------------------------------------------------------------------
    Masalah :
    A bank uses the following function to calculate the rate of interest (in percentage) 
    for a particular loan amount (in lakhs of dollars).
        r(a) = 15;       if 0.1 < a <= 1
        r(a) = 13.5;     if   1 < a <= 5
        r(a) = 12.5;     if   5 < a <= 10
        r(a) = 11.0;     if  10 < a <= 50

    Write a program that prompts the user to enter the amount of the loan and displays 
    the rate of interest. If the amount is less than $10,000 or more than $50,00,000, 
    display a message “Loan cannot be provided.”
