/****************************************************** ** Name: ** Filename: monetary.cpp ** Project #: Deitel & Deitel 2.51 ** Project Description: Modify the program in Fig 2.21 so it uses only integers for monetary values to calculate the compound interest. ** Output: Table with year and amount of deposit as it grows with interest rate ** Input: None ** Algorithm: Make all variables for money values as integers, then put into penny amount. Run loop till year <= 10 Calculate yearly amount using formula a = p ( 1 + r )^n Divide amount by 100 giving an integer result Divide amount using modulus to get remainder to add cents amount Print amount followed by period then print cents End program ******************************************************/ // Include files #include // used for cin, cout #include #include #include using namespace std; // Global Type Declarations // Function Prototypes void instruct (void); void pause (); //Global Variables - should not be used without good reason. int main () { // Declaration section int amount, // amount on deposit principal = 100000;// starting principal in pennies amount double rate = .05; // interest rate // Executable section instruct (); cout <<"Year" << setw ( 27 ) << "Amount on deposit\n" << endl; cout << setiosflags ( ios::fixed | ios::showpoint ) << setprecision ( 2 ); for ( int year = 1; year <= 10; year++ ) { amount = principal * pow ( 1.0 + rate, year ) ; cout << setw( 4 ) << year << setw( 18 ) << amount / 100 << '.'; if ( amount % 100 < 10 ) cout << '0' << amount % 100 << endl; else cout << amount % 100 << endl; } pause (); return 0; } void instruct (void) { // Declaration section // Executable section } void pause () { // Declaration section // Executable section cout << "\nPress any key to continue..."; getch(); cout << "\r"; cout << " "; cout << "\r"; } /* Program Output Year Amount on deposit 1 1050.00 2 1102.50 3 1157.62 4 1215.50 5 1276.28 6 1340.09 7 1407.10 8 1477.45 9 1551.32 10 1628.89 Press any key to continue... */
