need help badly

[gregorydouglas89]

i am trying to figure out how to do this question it says that i should do a switch and a if statement

Things On Us wants you to write a program to display fruit names and prices. If user enter
Letter Fruit Price
O or o Orange 0.99 each
G or g Grapes 1.49/ Lb.
M or m Mango 1.00 each

If user enter any other letter the program must display error message, please enter correct fruit code
Write program using switch and if statements.

[CodeWriter]

Who are "Things On Us" ?
So what have you done so far?

#include <iostream>
using namespace std;

int main(){

    char item = ' ';

    cout<<"Please enter O G or M and press Enter. ";
    cin >> item ;
    item = toupper(item);
    cout << endl << item << endl;
    if(item == 'O') {
        cout<<"Orange 0.99 each";
    } else if(item == 'G') {
        cout<<"Grapes 1.49/Lb.";
    } else if(item == 'M') {
        cout<<"Mango 1.0 each";
    } else {
        cout<<"invalid letter";
    }

    return 0;
}

for switch statement

#include <iostream>

using namespace std;

int main ( )
{
char O, o, M, m, G, g;




cout<<"Letter Fruit Price"<<endl;
cout<<"O or o Orange 00.99"<<endl;
cout<<"G or g Grapes 01.49"<<endl;
cout<<"M or m Mango 01.00"<<endl;


int code;
cout << "Enter the fruit code: " ;
cin>> code;

switch (code)
{
case 1:
if (code = o || O)
cout <<"Orange" << endl;
break;

case 2:
cout <<"Grapes" <<endl;

break;

case 3:
cout <<"Mango" <<endl;

break;

default:
cout <<"please enter correct fruit code" <<endl;
}
system ("pause");
return 0;

}

sorry this is what i have for switch statement

#include <iostream>

using namespace std;

int main ( )
{
char O, o, M, m, G, g




cout<<"Letter Fruit Price"<<endl;
cout<<"O or o Orange 00.99"<<endl;
cout<<"G or g Grapes 01.49"<<endl;
cout<<"M or m Mango 01.00"<<endl;


int code;
cout << "Enter the fruit code: " ;
cin>> code;

switch (code)
{
case O: case o:
cout <<"Orange" << endl;
break;

case G: case g:
cout <<"Grapes" <<endl;

break;

case M: case m:
cout <<"Mango" <<endl;

break;

default:
cout <<"please enter correct fruit code" <<endl;
}
system ("pause");
return 0;

}

Yes you can use case M: case m:
Below I have just converted any lowercase to uppercase.
What is the line char O, o, M, m, G, g for?

// for switch statement

#include <iostream>

using namespace std;

int main ( )
{

cout<<"Letter Fruit Price"<<endl;
cout<<"O or o Orange 00.99"<<endl;
cout<<"G or g Grapes 01.49"<<endl;
cout<<"M or m Mango 01.00"<<endl;


char code;
cout << "Enter the fruit code: " ;
cin  >> code;
code = toupper(code);

switch (code)
{
    case 'O':
    cout <<"Orange" << endl;
    break;

    case 'G':
    cout <<"Grapes" <<endl;
    break;

    case 'M':
    cout <<"Mango" <<endl;
    break;

    default:
    cout <<"please enter correct fruit code" <<endl;
}
system ("pause");
return 0;

}

@OP character constants have an apostrophe {'}around them so your switch statement will not work.

Example:
case O: case o: should be case 'O': case 'o':

oh ok now i get it. i did this program also. i compiled ok but when i test the program to put in my first name it does not prompt me to do the last name, nor to enter other information.

using namespace std;
int main()
{

int hrsWorked;
double firstName, lastName;
double payRate, taxRate, grossPay, taxAmount, netWeeklyPay, jobStatus;


char fullTime = 'F' or 'f';
char partTime = 'P' or 'p';
jobStatus = fullTime or partTime;

//user inputs
cout << "Please enter your Name:\n " << endl;
cin >> firstName;

cout << "Please enter your Last Name:\n " << endl;
cin >> lastName;

cout << "Are you Fulltime or Parttime:\n" << endl;
cout<<"F. Full Time"<<endl;
cout<<"P. Part Time:\n "<<endl;
cin >> jobStatus;

cout << "Please enter your payRate:\n " << endl;
cin >> payRate;
cout << "Please enter total hours of work:\n " << endl;
cin >> hrsWorked ;






grossPay = payRate * hrsWorked;

taxRate = 0.12;

taxAmount = grossPay * taxRate;

netWeeklyPay = grossPay - taxAmount;


if(hrsWorked > 40)
cout << "You will get Over Time Pay" << endl;


else if(hrsWorked <= 40)
cout << "You will not get Over Time Pay" << endl;


cout<<"Employee's First Name: = "<<firstName<<endl;
cout<<"Employee's Last Name = "<<lastName<<endl;
cout<<"Hours Worked = "<<hrsWorked<<endl;
cout<<"Pay Rate = "<<payRate<<endl;
cout<<"Tax Rate = "<<taxRate<<endl;
cout<<"Gross Pay = "<<grossPay<<endl;
cout<<"Tax Amount = "<<taxAmount<<endl;
cout<<"Net Weekly Pay = "<<netWeeklyPay<<endl;

system("pause");
return 0;
}

Not sure why it doesn't work, still learning this stuff myself, very complicated compared with the BASIC language I am familiar with.
It worked like this but not how you would like to input the data.

//user inputs
//cout << "Enter firstName, lastName, jobStatus (F or P), payRate, hours worked:\n " << endl;
//cin  >> firstName >> lastName >> jobStatus >> payRate >> hrsWorked; 

After some searching for solutions this seems to work but not sure why. It seems to use stringstream as a strange way to convert a string to a number type.

#include <iostream>
#include <string>
#include <sstream>

using namespace std;
int main()
{

int hrsWorked;
string firstName, lastName;
double payRate, taxRate, grossPay, taxAmount, netWeeklyPay;
string  jobStatus;
string  inStr;

string fullTime;
string partTime;


//user inputs
//cout << "Enter firstName, lastName, jobStatus (F or P), payRate, hours worked:\n " << endl;
//cin  >> firstName >> lastName >> jobStatus >> payRate >> hrsWorked;
//user inputs


cout << "\nPlease enter your First Name: ";
getline (cin,firstName);

cout << endl << "\nPlease enter your Last Name: ";
getline (cin,lastName);

cout << endl << "\nAre you Fulltime or Parttime?\n";
cout << "F. Full Time\n";
cout << "P. Part Time:\n";
//cin >> partTime;
getline (cin,inStr);
cout << partTime;

cout << endl << "Please enter your payRate: ";
getline (cin,inStr);
stringstream(inStr) >> payRate;

cout << endl << "\nPlease enter total hours of work: ";
getline (cin,inStr);
stringstream(inStr) >> hrsWorked;
cout << hrsWorked << endl;

grossPay = payRate * hrsWorked;

taxRate = 0.12;

taxAmount = grossPay * taxRate;

netWeeklyPay = grossPay - taxAmount;


if(hrsWorked > 40)
cout << "You will get Over Time Pay" << endl;


else if(hrsWorked <= 40)
cout << "You will not get Over Time Pay" << endl;


cout<<"Employee's First Name: = "<<firstName<<endl;
cout<<"Employee's Last Name = "<<lastName<<endl;
cout<<"Hours Worked = "<<hrsWorked<<endl;
cout<<"Pay Rate = "<<payRate<<endl;
cout<<"Tax Rate = "<<taxRate<<endl;
cout<<"Gross Pay = "<<grossPay<<endl;
cout<<"Tax Amount = "<<taxAmount<<endl;
cout<<"Net Weekly Pay = "<<netWeeklyPay<<endl;

system("pause");
return 0;
}

You had a number of errors:
1. Names etc are strings unless you were asking for employee numbers which are unlikely to be 'doubles'.
2. Your if statement wasn't wrong so much as badly constructed - unnecessarily complicated.
3. Your char variables were wrong - look carefully how they are tidied up, corrected and rationalized. :)

everyone thanks for your help how can i repay you
