Need help with some code....

[darren200184]

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:

#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.

#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.

#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

Sweet! I got it know, thanks fellas.

Here is my final 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.

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:

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:

#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.
