question with strings

[gdarian216]

I am writting a program that gets a line of input from a user and puts that in a string. Then it needs to correct whitespace and capitalization. If there is more then one space of whitespace between words change it to one space and if it is a period add a space.

this is what i have so far and Im trying to get the whitespace right.

#include<string>
#include<iostream>
using namespace std;
 
int main() {
 
        cout << "enter sentence and hit enter";
        string  s1;
 
        getline(cin,s1);
 
         if(s1 != " ");
        {
 
                char seporator = ' ';
                if (s1[s1.length()-1] == '.')
                { seporator = '\n';
                }
 
                cout << s1 << seporator;
                }
 
        while(s1 != " ");
 
        return(0);
 
}

You have you loop wrong, you need to be looping down the string checking each character. For each character you will probably need to set some flags, was it a space?, do you need to capital ise the next character.

Then as you read each character you can use the flags to take appropriate action

LastCharacterWasSpace = false
LastCharacterRequiresSpace = false
CapitaliseNextNonSpace = true
 
 
FOREACH Character IN String
    IF Character Is Space
        IF LastCharacterWasSpace = true
            REMOVE Character FROM String
        ELSE
            LastCharacterWasSpace = true
            LastCharacterRequiresSpace = false
        ENDIF
    ELSE // Character is not space
        IF LastCharacterRequiresSpace
            INSERT Space INTO String
            LastCharacterRequiresSpace = false
        ENDIF
 
        LastCharacterWasSpace = false
 
        IF Character = FullStop
            LastCharacterRequiresSpace = true
            CapitaliseNextNonSpace = true
        ELSE IF Character = Comma
            LastCharacterRequiresSpace = true
        ELSE
            IF CapitaliseNextNonSpace = true
                Character = UpperCase( Character )
            ELSE
                Character = LowerCase( Character )
            ENDIF
            CapitaliseNextNonSpace = false
        ENDIF
    ENDIF
ENDFOR
