Need help with some code....

I'm new here and I need to know how to change a sentence in lowercase to uppercase and output the uppercase sentence to a file.
What other code do I need for this?
Here is what i have so far:

Code:

---

#include <iostream>
#include <fstream>
#include <cctype>
#include <cstdlib>

using namespace std;

int main()
{

        using namespace std;
        ofstream out_stream;

       
        out_stream.open("lowertoupperoutfile.dat");

        out_stream << ("hello this is the paragraph part of the project.\n");

        out_stream.close();
       

        return 0;

}

---

here is a c++ solution that only converts the string from lower-case to upper-case. After the conversion your program needs to write it out to a file.

Code:

---

#include <iostream>
#include <string>
#include <algorithm>
using namespace std;

int main()
{
        string s = "this is lower case";
        transform(s.begin(),s.end(),s.begin(),toupper);
        cout << s << endl;
        return 0;
}

---

you should learn to search the boards -- here it another solution.

OOooo better than mine... and you beat me to the punch.

Code:

---

#include <iostream>
#include <string>
#include <cctype>

using namespace std;

int main() {

    string str1;

    cout << "Enter in a string in lowercase \n";
    getline(cin, str1,'\n');

    for (int x = 0; str1[x] !=0; x++)
        str1[x] = toupper(str1[x]);

    cout << str1;

    return 0;

    }

I learned that here on this board too :D

Sweet! I got it know, thanks fellas.

Here is my final code:

Code:

---

#include <iostream>
#include <fstream>
#include <cctype>
#include <algorithm>
#include <string>

using namespace std;

int main()
{

        using namespace std;
        ofstream out_stream;

       
        out_stream.open("lowertoupperoutfile.dat");

        string s = ("hello this is the paragraph part of the project.\n");
        transform(s.begin(),s.end(),s.begin(),toupper);
       
        out_stream << s << endl;
       
       
        out_stream.close();
       

        return 0;

}

You guys are EPIC.

Code:

---

string s = ("hello this is the paragraph part of the project.\n");

---

You can omit the parentheses -- that is an assignment, not a function call. Or do it like this:

Code:

---

string s ("hello this is the paragraph part of the project.\n");

Ok, cool.

I have one more question/project that I need to ask.
I hope this isn't to much to ask but here goes, you don't have to look at it if you don't want but here:

I need to add another loan to it to make it 2 loans and input a function called initialize _loan to initialize the loan struct and also display the loan and monthly payment for each.

I don't really know where to add or put a second loan part to this, and put the function in there. Any help would be appreciated. I'm kind of lost. Here is the first loan code part:

Code:

---

#include<iostream>
#include<cmath>
using namespace std;

struct Loan
{
        int ID;
        float amount;
        float rate;
        int term;
};

float payment(Loan 1);

int main()
{
        Loan loan1;
        float monthly_payment;

        cout << "Enter the ID of this loan \n";
        cin >> loan1.ID;

        cout << "Enter the amount of this loan \n";
        cin >> loan1.amount;

        cout << "Enter the annual interest rate of this loan (in%)\n";
        cin >> loan1.term;

        monthly_payment = payment(loan1);

        cout << "The monthly payment for loan " << loan.ID << "is:" <<monthly_payment << endl;

        return 0;

}

float payment(Loan 1)
{
        1.rate/1200;
        return 1.amount*1.rate*( pow((1.rate+1),1.term)/(pow((1.rate+1),1.term) - 1));
}

Thanks in advance.
