PROGRAM C++ PELAYANAN RUMAH SAKIT Konsep: - program C++ berdiagram objek. - jenis program ada INPUT --> OUTPUT.. #include <iostream> #include <iomanip> using namespace std; // Function prototypes char getchoice(); double patientcharges(int, double, double, double); // In-patient double patientcharges(double, double); // Out-patient int main() char patienttype; // I=in-patient, O=out-patient int days; // Number of days of hospital stay double roomrate, // Daily room rate medication, // Total medication charges services, // Total for tests and other services totalcharges; // Total of all charges // Input and validate patient type cout << "This program will compute patient hospital charges.\n"; cout << "Enter I for in-patient or O for out-patient: "; patienttype=getchoice(); //Process the menu selection switch (patienttype) //Inpatient case 'I': case 'i': cout << "The number of days spent in the hospital: "; cin >> days; cout << "The daily rate: "; cin >> roomrate; cout << "Charges for hospital service: "; cin >> services; cout << "Hospital medicaion charges; "; cin >> medication; cout << patientcharges (days, roomrate, services, medication) << endl; totalcharges=(days*roomrate) + services + medication; break;

5 cin >> letter; // Return the choice return letter; /*************************************... * patientcharge * * This function is called by main to calculate and return * * total patient charges for in-patients * **************************************... double patientcharges(int days, double rate, double med, double serv) return (days*rate) + med + serv; // end overload function patientcharges /*************************************... * patientcharge * * This function is called by main to calculate and return * * total patient charges for out-patients * **************************************... double patientcharges(double med, double serv) return med + serv; // end overload function patientcharges B. Program berstruktur pengulangan dengan counter: Petunjuk: 1. Gunakan langkah-langkah pembuatan template program seperti pada program sederhana I ( Hello World!) yang lalu, tetapi gunakan Project_name yang berbeda,misalnya Program5 2. Gantilah blok program fungsi main ( ingat,yang dimaksud blok adalah barisan perintah diantara dan dari fungsi main),dengan yang berikut: int counter; /* number of grade to be entered next */ int grade; /* grade value */ int total; /* sum of grades input by user */ int average; /* average of grades */

6 /* initialization phase */ total = 0; /* initialize total */ counter = 1; /* initialize loop counter */ /* processing phase */ while ( counter <= 10 ) /* loop 10 times */ printf( "Enter grade: " ); /* prompt for input */ scanf( "%d", &grade ); /* read grade from user */ total = total + grade; /* add grade to total */ counter = counter + 1; /* increment counter */ /* end while */ /* termination phase */ average = total / 10; /* integer division */ printf( "Class average is %d\n", average ); /* display result */ return 0; /* indicate program ended successfully */ Output Program: Enter grade: 98 Enter grade: 76 Enter grade: 71 Enter grade: 87 Enter grade: 83 Enter grade: 90 Enter grade: 57 Enter grade: 79 Enter grade: 82 Enter grade: 94 Class average is 81 C. Program berstruktur pengulangan dengan sentinel: Petunjuk: 1. Gunakan langkah-langkah pembuatan template program sama seperti di atas, tetapi gunakan Project_name yang berbeda,misalnya Program6 2. Gantilah blok program fungsi main,dengan yang berikut: int counter; /* number of grades entered */ int grade; /* grade value */ int total; /* sum of grades */ float average; /* number with decimal point for average */ /* initialization phase */ total = 0; /* initialize total */ counter = 0; /* initialize loop counter */ /* processing phase */ /* get first grade from user */

7 printf( "Enter grade, -1 to end: " ); /* prompt for input */ scanf( "%d", &grade ); /* read grade from user */ /* loop while sentinel value not yet read from user */ while ( grade!= -1 ) total = total + grade; /* add grade to total */ counter = counter + 1; /* increment counter */ /* get next grade from user */ printf( "Enter grade, -1 to end: " ); /* prompt for input */ scanf("%d", &grade); /* read next grade */ /* end while */ /* termination phase */ /* if user entered at least one grade */ if ( counter!= 0 ) /* calculate average of all grades entered */ average = ( float ) total / counter; /* avoid truncation */ /* display average with two digits of precision */ printf( "Class average is %.2f\n", average ); /* end if */ else /* if no grades were entered, output message */ printf( "No grades were entered\n" ); /* end else */ return 0; /* indicate program ended successfully */

8 Output Program: Enter grade, -1 to end: 75 Enter grade, -1 to end: 94 Enter grade, -1 to end: 97 Enter grade, -1 to end: 88 Enter grade, -1 to end: 70 Enter grade, -1 to end: 64 Enter grade, -1 to end: 83 Enter grade, -1 to end: 89 Enter grade, -1 to end: -1 Class average is Enter grade, -1 to end: -1 No grades were entered D. Program berstruktur kondisi switch dan pengulangan dengan sentinel.sentinel yang digunakan adalah karakter EOF yaitu apabila user menekan tombol Ctrl+Z Petunjuk: 1. Gunakan langkah-langkah pembuatan template program sama seperti program sebelumnya, tetapi gunakan Project_name yang berbeda,misalnya Program7 2. Gantilah blok program fungsi main,dengan yang berikut: int grade; /* one grade */ int acount = 0; /* number of As */ int bcount = 0; /* number of Bs */ int ccount = 0; /* number of Cs */ int dcount = 0; /* number of Ds */ int fcount = 0; /* number of Fs */ printf( "Enter the letter grades.\n" ); printf( "Enter the EOF character to end input.\n" ); /* loop until user types end-of-file key sequence */ while ( ( grade = getchar() )!= EOF ) /* determine which grade was input */ switch ( grade ) /* switch nested in while */ case 'A': /* grade was uppercase A */ case 'a': /* or lowercase a */ ++acount; /* increment acount */ break; /* necessary to exit switch */ case 'B': /* grade was uppercase B */ case 'b': /* or lowercase b */ ++bcount; /* increment bcount */ break; /* exit switch */

9 case 'C': /* grade was uppercase C */ case 'c': /* or lowercase c */ ++ccount; /* increment ccount */ break; /* exit switch */ case 'D': /* grade was uppercase D */ case 'd': /* or lowercase d */ ++dcount; /* increment dcount */ break; /* exit switch */ case 'F': /* grade was uppercase F */ case 'f': /* or lowercase f */ ++fcount; /* increment fcount */ break; /* exit switch */ case '\n': /* ignore newlines, */ case '\t': /* tabs, */ case ' ': /* and spaces in input */ break; /* exit switch */ default: /* catch all other characters */ printf( "Incorrect letter grade entered." ); printf( " Enter a new grade.\n" ); break; /* optional; will exit switch anyway */ /* end switch */ /* end while */ /* output summary of results */ printf( "\ntotals for each letter grade are:\n" ); printf( "A: %d\n", acount ); /* display number of A grades */ printf( "B: %d\n", bcount ); /* display number of B grades */ printf( "C: %d\n", ccount ); /* display number of C grades */ printf( "D: %d\n", dcount ); /* display number of D grades */ printf( "F: %d\n", fcount ); /* display number of F grades */ return 0; /* indicate program ended successfully */ Output Program: Enter the letter grades. Enter the EOF character to end input. a b c C A d f C E Incorrect letter grade entered. Enter a new grade. D

10 A b ^Z Totals for each letter grade are: A: 3 B: 2 C: 3 D: 2 F: 1 E.
