Thread: capitalization trick

Code:

#include <iostream>
using namespace std;

int main()
{
	char string[81];

	cout << "Enter a string" << endl;

	cin.getline(string, 81);

	cout << endl << string << endl;

	return 0;
}

Is there a way to get a string to print out as:

Hi, How Are You?

if I enter:

hi, how are you?

I'm guessing to capitalize the first word of a sentence, you would need to detect when the space key is entered and use the toupper function somewhere.

you'll need to parse the string, and find the first letter of each word and use toupper().

Code:

         cout << "Please enter your name: ";
	getline(cin,name);

	if((name[0] > 97) && (name[0] < 122))
	 {
		name[0] -= 32;
	 }

Parse the string?

the code i posted will capitalize the first letter in "name";

	 {

	 }

Can't you make this a little easier for me by using my code example?

I'm not even familiar with getline(cin,name);

I use cin.getline();

Also, isn't it easier with the toupper method? Besides, I remember someone telling me that the - 32 trick isn't portable to other platforms.

Code:

#include <iostream>
using namespace std;
int main()
{
char string[81];
cout << "Enter a string" << endl;
cin.getline(string, 81);

if((string[0] > 97) && (string[0] < 122))
 {
string[0] -= 32;
 }


cout << endl << string << endl;

return 0;
}

Thanks RoD, but...

"Also, isn't it easier with the toupper method? Besides, I remember someone telling me that the - 32 trick isn't portable to other platforms."

hmm try this

Code:

#include <iostream>
#include <ctype.h>

using namespace std;
int main()
{
char string[81];
cout << "Enter a string" << endl;
cin.getline(string, 81);

string[0] = toupper(string[0]);
	
cout << endl << string << endl;
return 0;
}

return 0;
}

Thanks again, RoD. But why did you include <ctype.h>? As far as I know, that code will work perfectly without it...I think...

Oh, I forgot about that space checking thing. I wanted the output of "hi, how are you?" to look like "Hi, How Are You?" not "Hi, how are you?

Would a for loop be better than a while loop for this process?

Code:

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

int main(int argc, char** argv)
{
   using namespace std;
   string in;
   getline(cin, in);

   in[0] = toupper(in[0]);
   for (i = 0; i < in.length() - 1; ++i)
   {
       if (isspace(in[i]))
          in[i+1] = toupper(in[i+1]);
   }
}
