Thread: Count number of uppercase words in array

Perhaps "words" are text delimited by "spaces"?

My main issue is trying to figure out when a word begins/ends.

What do you define as a word in the first place?

Recall that (cin >> x) reads into x and skips whitespace between 'words'.

Just replace it with

message[i]

and see if it makes more sense.

Use the space-button!!!

Can someone please help me. This assignment is due midnight tonight. All I'm doing is asking for help. I have tried so many things, this is like my 3rd version:

Code:

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

void array (char b[], int *bmax);

int main ( )
{							//Open main
int max=56;
char *b = new char [ max];
b=&b[0];

cout << "enter string\n";
	cin.getline(b, max);
array (b, &max);
return 0;
}						// end main

void array (char b[], int *bmax)
{
	int count =0;
	char ch;

	ch= *(b);

	for ( *(b); ch < *bmax; b++)
	while (ch != ' ' && ch != '\n')
		{
			if (isupper (ch))
			{
			count ++;
			cout << ch;
			}
			break;
		}			// close if

	delete []b;
	cout << "\n" <<count;
}				//close void

*edited code*

Code:

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

void array (char b[], int *bmax);


const int MaxSize = 60;

int main ( )
{//Open main

        char *buffer = new char[MaxSize];

        cout << "Please enter the string to evaluate:\n";

        cin >> noskipws;
        cin.getline(&buffer[0],MaxSize);

        cout << "Message entered is: " << buffer << "\n";

        int upcase_words = 0;
        for (int i=0; i<MaxSize && buffer[i]!='\0'; i++) {

                if (i==0 && isupper(buffer[i])) {
                        upcase_words++;
                } else if (buffer[i-1]==' ' && isupper(buffer[i])) {
                        upcase_words++;
                }
        }

        cout << upcase_words << " words start with uppercase\n";

}//close void

Here's a working version of what you want to achieve, although it just counts the words, it does not output which words are. Plus, the code is not that good but it was written in a hurry.

[edit]

this is like my 3rd version

Man i must tell you i feel really dumb for taking the time to write this code for you, if i had spotted this line before you can rest assured you would not have this code. Nevertheless i decided to leave the code, i just really hope that you take the time to try and LEARN SOMETHING from this as from what concerns me you won't get any other homework done for you...

Sometimes you just need to take a step back and ask what you really want to do. Since you probably have submitted your assignment, I suppose it is safe to show you how your homework might have been done

The way I see it, this is what you want to do:
1. Read a line.
2. Print what was read (i.e. the line).
3. Count number of capitalised words in this line.
4. Print the count and the capitalised words.

#1 and #2 can be solved by using a C++ string and getline().
#3 and #4 can be solved by using a (dynamic) array to store the words.
Extracting the words from the string is perhaps the most difficult part, but formatted input with std::istream (e.g. std::cin >> x) pretty much solves that for you.

Code:

#include <string>
#include <vector>
#include <iostream>
#include <sstream>
#include <cctype>

typedef std::string WordType;
typedef std::vector<WordType> WordListType;

int main() {
	// Get the input sentence
	std::cout << "Enter a sentence: ";
	std::string sentence;
	std::getline(std::cin, sentence);
	std::cout << "Sentence entered is: " << sentence << "\n";

	// Pass the input sentence to a stringstream
	std::stringstream wordstream(sentence);

	WordListType words;
	WordType word;

	// Extract words from the wordstream using formatted input
	while (wordstream >> word) {
		// Place capitalised words into word list
		if (std::isupper(word[0])) {
			words.push_back(word);
		}
	}

	std::cout << "Number of capitalised words: " << words.size();

	// Print list of capitalised words unless there are none
	if (!words.empty()) {
		std::cout << "\nThe capitalised words are: ";
		for (WordListType::const_iterator i = words.begin(); i != words.end(); ++i) {
			std::cout << *i << " ";
		}
	}

	std::cout << std::endl;
	return 0;
}
