Expand Post »

here's my code, don't see why it doesn't print out

#include <iostream>
 
using namespace std;
 
int main()
{
    cout<<"enter a passage into input to find out how difficult it is to read\n";
    string passage;
    cin>>passage;
    char letter;
    int space=0;
    while(letter!='\n')
    {
        if(isspace(cin.peek())&&letter=='\n')
        {
            cout<<"from space";
            space=space++;
        }
    }
    cout<< space;
    return 0;
}
#include <iostream>

using namespace std;

int main()
{
    cout<<"enter a passage into input to find out how difficult it is to read\n";
    string passage;
    cin>>passage;
    char letter;
    int space=0;
    while(letter!='\n')
    {
        if(isspace(cin.peek())&&letter=='\n')
        {
            cout<<"from space";
            space=space++;
        }
    }
    cout<< space;
    return 0;
}

Re: so i want to find out the number of spaces in a sentence, is this correct?

so it prints out but is an infinite loop, need to check if they do enter '\n' character how to do that?

It may have minor errors as i have written directly..that you can solve easly

C++ Syntax (Toggle Plain Text)
#include<iostream.h>
#include<conio.h>
#include<stdio.h>
 
void main()
{
clrscr();
char st[25];
cout<<"Enter String:- ";
gets(st);
 
int n; 
n = strlen(st);
int i;
int count=0;
for(i=0;i<=n;i++)
{
         while(str[i] == NULL)
         {
                   count=count+1;
          }
}
 
cout<<endl<<"Space:-"<<count;
 
getch();
}
#include<iostream.h>
#include<conio.h>
#include<stdio.h>

void main()
{
clrscr();
char st[25];
cout<<"Enter String:- ";
gets(st);

int n; 
n = strlen(st);
int i;
int count=0;
for(i=0;i<=n;i++)
{
         while(str[i] == NULL)
         {
                   count=count+1;
          }
}

cout<<endl<<"Space:-"<<count;

getch();
}

nirav99,

Use BB code tag. Source program must be surrounded with BB code tags: See # icon at toolbar and also read How to use bb code tags?.

basically i am trying to create a readibility index so i need the number of vowels, words and sentences. I am stuck on how to approach this.

<div> <div class="quote"> <div class="quote_header">   Quote ...   </div> <blockquote class="quote_body"> cin>>passage; </blockquote> </div> </div>
<div> <div class="quote"> <div class="quote_header">   Quote ...   </div> <blockquote class="quote_body"> cin>>passage; </blockquote> </div> </div>

cin would stop reading as soon as it encounters a space !
Use getline instead:

C++ Syntax (Toggle Plain Text)
getline (cin  ,  passage)
getline (cin  ,  passage)

C++ Syntax (Toggle Plain Text)
<div> <div class="quote"> <div class="quote_header">   Quote ...   </div> <blockquote class="quote_body"> while(letter!='\n')
    {
        cin.get(letter);
        while(letter=" ");  //<<extra character makes it redundant;) 
        //while(isspace(cin.peek())&&letter=='\n')
        {
            cin.get(letter);
            cout<<"the letter is"<<letter;
            space++;
        }
    } </blockquote> </div> </div>
<div> <div class="quote"> <div class="quote_header">   Quote ...   </div> <blockquote class="quote_body"> while(letter!='\n')
    {
        cin.get(letter);
        while(letter=" ");  //<<extra character makes it redundant;) 
        //while(isspace(cin.peek())&&letter=='\n')
        {
            cin.get(letter);
            cout<<"the letter is"<<letter;
            space++;
        }
    } </blockquote> </div> </div>

Instead ,

for (int  i = 0 ; i < passage.length() ;i++)
    if (isspace(passage[i]) )
         space++;
for (int  i = 0 ; i < passage.length() ;i++)
    if (isspace(passage[i]) )
         space++;

Re: so i want to find out the number of spaces in a sentence, is this correct?

gives me weird error of includes atleast one deprecated or antiquated header.
And it doesn't seem to capture # of spaces.

C++ Syntax (Toggle Plain Text)
#include<iostream.h>
 
using namespace std;
int main()
{
string passage;
int space;
cout<<"enter the passage to find out readability index";
cin>>passage;
getline(cin,passage);
    for (int  i = 0; i < passage.length(); i++)
    {
        if (isspace(passage[i]) )
        {
            space++;
        }
        cout<<"the number of spaces is"<<space;
    }
}
#include<iostream.h>

using namespace std;
int main()
{
string passage;
int space;
cout<<"enter the passage to find out readability index";
cin>>passage;
getline(cin,passage);
    for (int  i = 0; i < passage.length(); i++)
    {
        if (isspace(passage[i]) )
        {
            space++;
        }
        cout<<"the number of spaces is"<<space;
    }
}

Re: so i want to find out the number of spaces in a sentence, is this correct?

Change <iostream.h> to <iostream>, that's the standard C++ way.

Also delete the line cin >>passage . You're already taking in input with getline(), so no need to do it twice.

And also change int space; to int space = 0; . How can your program ++ if it doesn't know the variable's initial value?

Also put this line: cout<<"the number of spaces is"<<space; outside your for loop. You only want to display this messsage once right?

[edit]

Also (

) , you might want to put a cin.get() at the end of your loop (right after you output your message. This keeps the console open for you to read what the output of your program is. If you don't put it there, your console window will disappear to fast.
You could also run it from a console window you've already opened, but my guess is that you do not yet know how this works.
