How to split a string and store the words in a separate array without using strtok or istringstream and find the greatest word?? I am only a beginner so I should accomplish this using basic functions in string.h like strlen, strcpy etc. only. Is it possible to do so?? I've tried to do this and I am posting what I have done. Please correct my mistakes.

#include<iostream.h>
#include<stdio.h>
#include<string.h>
void count(char n[])
{
    char a[50], b[50];
    for(int i=0; n[i]!= '\0'; i++)
    {
        static int j=0;
        for(j=0;n[j]!=' ';j++)
        {
            a[j]=n[j];
        }
        static int x=0;
        if(strlen(a)>x)
        {
            strcpy(b,a);
            x=strlen(a);
        }
    }
    cout<<"Greatest word is:"<<b;
}

int main( int, char** )
{
    char n[100];
    gets(n);
    count(n);
}

The code in your example looks like it's written in C. Functions like strlen and strcpy originates in C (although they are also part of the C++ standard library for compatibility via the header cstring).

You should start learning C++ using the Standard Library and things will get much easier. Things like splitting strings and finding the greatest element can be done using a few lines of code if you use the functions in the standard library, e.g:

// The text
std::string text = "foo bar foobar";

// Wrap text in stream.
std::istringstream iss{text};
// Read tokens from stream into vector (split at whitespace).
std::vector<std::string> words{std::istream_iterator<std::string>{iss}, std::istream_iterator<std::string>{}};
// Get the greatest word.
auto greatestWord = *std::max_element(std::begin(words), std::end(words), [] (const std::string& lhs, const std::string& rhs) { return lhs.size() < rhs.size(); });

Edit: If you really want to dig down in the nitty-gritty parts using only functions from std::string, here's how you can do to split the text into words (I leave finding the greatest word to you, which shouldn't be too hard):

// Use vector to store words.
std::vector<std::string> words;
std::string text = "foo bar foobar";

std::string::size_type beg = 0, end;
do {
    end = text.find(' ', beg);
    if (end == std::string::npos) {
        end = text.size();
    }
    words.emplace_back(text.substr(beg, end - beg));
    beg = end + 1;
} while (beg < text.size());

C program to split string into the words separated by spaces , to extract words out of a string and store them in different array in c++ How to split a string and store the words in a separate array without  1. Make a string stream. 2. extract words from it till there are still words in the stream. 3. Print each word on new line. This solution works even if we have multiple spaces between words. C++. Java.

I would write two functions. The first one skips blank characters for example

const char * SkipSpaces( const char *p )
{
    while ( *p == ' ' || *p == '\t' ) ++p;

    return ( p );
}

And the second one copies non blank characters

const char * CopyWord( char *s1, const char *s2 )
{
    while ( *s2 != ' ' && *s2 != '\t' && *s2 != '\0' ) *s1++ = *s2++;
    *s1 = '\0';

    return ( s2 );
}

try to get a word in a small array(obviously no word is >35 characters) you can get the word by checking two successive spaces and then put that array in strlen() function and then check if the previous word was larger then drop that word else keep the new word after all this do not forget to initialize the word array with '\0' or null character after every word catch or this would happen:- let's say 1st word in that array was 'happen' and 2nd 'to' if you don't initialize then your array will be after 1st catch : happen and 2nd catch : *to*ppen

Program to extract words from a given String, In this lesson we'll learn how to split a string into several tokens using strtok function. Suppose, we've the following string and we want to extract the individual words. It puts NULL characters ('\0') at the delimiter position after every call to strtok so that tokens can be tracked. strtok also internally Next: Array Of C String. 1) instead of the array word just containing a word, printing it and then emptying itself out its adding each word, appending it, so it's printing the whole input string in chunks, each time it prints it appends a new word to it 2) since my do-while loop terminates once c = null charater, it does not print out the last word. I'm not sure how to correct this Thank You

Try this. Here ctr will be the number of elements in the array(or vector) of individual words of the sentence. You can split the sentence from whatever letter you want by changing function call in main.

#include<iostream>
#include<string>
#include<vector>
using namespace std;
void split(string s, char ch){
    vector <string> vec;
    string tempStr;
    int ctr{};
    int index{s.length()};
    for(int i{}; i<=index; i++){
        tempStr += s[i];
        if(s[i]==ch || s[i]=='\0'){
            vec.push_back(tempStr);
            ctr++;
            tempStr="";
            continue;
        }
    }
    for(string S: vec)
        cout<<S<<endl;
}
int main(){
    string s;
    getline(cin, s);
    split(s, ' ');
    return 0;
}

Beginning C: From Novice to Professional, How to extract words out of a string and store them in different array in c++ - c++ The code in your example looks like it's written in C. Functions like strlen and  Java program to swap first and last characters of words in a sentence; Frequency of smallest character in first sentence less than that of second sentence; Check if the given string of words can be formed from words present in the dictionary; Count words that appear exactly two times in an array of words; Calculate the difficulty of a sentence

Ivor Horton's Beginning ANSI C++: The Complete Language, C programming, exercises, solution: Write a program in C to split string by space into words. Using split function, we can split the string into a list of words and is most generic and recommended method if one wished to accomplish this particular task. But drawback is that it fails in the cases in string contains punctuation marks. # Python3 code to demonstrate. # to extract words from string. # using split () # initializing string.

Beginning C, 5th Edition, #define MAXWORDS 500 /* Maximum number of different words “/ #define the additional arrays and working storage that you'll need for extracting the words from The words array stores up to MAXWORDS word strings of length WORDLEN, find a new word, you'll store it in the next available position in the words array  Cell Arrays of Character Vectors. To store text as a character vector, enclose it single quotes. Typically, a character vector has text that you consider to be a single piece of information, such as a file name or a label for a plot. If you have many pieces of text, such as a list of file names, then you can store them in a cell array.

Comments
  • for spliting the string check this stackoverflow.com/questions/236129/…
  • Notice two things: 1.) That's more C than C++ - the tag 'C++' is confusing here. 2.) <iostream.h> is deprecated - better use <iostream> instead and write 'std::cout' or 'using namespace std;' at the top of your program
  • Is the target array supposed to equal the source array minus white space? Because that's a trivial exercise. Or is it supposed to be an array of literal strings (ie: char*s)? (Of course, you should be using vectors and stl strings but this looks like homework, in which you're expected to suffer.)
  • For the first method, you need this: #include <sstream>
  • Watch out for space on the end of a line.
  • Why is no word more than 20 chars? antidisestablishmentarianism, Supercalifragilisticexpialidocious. Quite apart from that this answer needs some serious attention as I doubt anyone gets what you're trying to describe - and on top of that I'm not sure we yet know what the questioner is even trying to achieve.
