Obviously, you'd need more than a switch statement.

Start by converting each of your 7 statements into this form:

case 4: xRate = 104.390; break; // Japan yen

I agree with EddiJ: Either there is *no* switch statement as in code below or there are more than one switch statements. The file format this code is using is:

The first line is US Dollar amount

10000

Canda dollar

1.01615

EuroZone euro

.638490

India rupee

40.1798

Japan yen

104.390

Mexico peso

10.4613

South Africa rand

7.60310

United Kingdom pound

.504285

In case you have questions, just drop an e-mail :O)

int main()

vector v;

read_file("convert.txt", v);

copy(v.begin(), v.end(), ostream_iterator(cout, "\n"));

return 0;

}

I'm am very confused on this program can anyone help me make a program that converts US dollars to a different currency here are the currencies and exchange rates.

1. Canda dollar - 1.01615

2. EuroZone euro - .638490

3. India rupee - 40.1798

4. Japan yen - 104.390

5. Mexico peso - 10.4613

6. South Africa rand - 7.60310

7. United Kingdom pound - .504285

Any help is appreciated and I have to use switch statements only
