    Unhappy stuck with toupper

    I'm trying to get my program to convert only the first character of each word typed in to caps. here's what I have, could someone give me some clues/pointers on what I am doing wrong please?


    Code:
    #include <stdio.h>
    #include <iostream>
    using namespace std;
    
    int main (int argc, char *argv[], char **env)
    {
    	char c, lastc = ' ' ;
    	c = cin.get() ;
    	do {
    		
    		if ( isspace( lastc ) )
    
    		cout.put ( toupper( c ) ) ;
    
    		lastc = c ;
    		
    		c = cin.get() ;
    	} while ( !cin.eof()) ;
    }

    You can start with including the correct header:
    Code:
    #include <cctype>

    You're not handling every case. Try listing, in words, what should happen for each character.

    knock yourself out

    Code:
    string StringToLower(string strToConvert)
    {//change each element of the string to lower case
        for(unsigned int i=0;i<strToConvert.length();i++)
        {
            strToConvert[i] = toupper(strToConvert[i]);
        }
        return strToConvert;//return the converted string
    }

    Way to be useful...

    `StringToLower' == `toupper'?

    Oh crap ok fine I am sorry I did not read the question correctly

    here is better version

    Code:
    string StringToWhatever(string strToConvert)
    {
        bool space = false; // to see if space was encountered
        for(unsigned int i=0;i<strToConvert.length();i++) // go through the whole string
        {
            if(space) // if space was encountered change the char to uppercase
            {
                strToConvert[i] = toupper(strToConvert[i]); // to uppercase
                space = false; // space is false
           }
            if(strToConvert[i].compare(" ")==0)
                space = true;
            
        }
        return strToConvert;//return the converted string
    }
    Sorry about that

    >_<

    Okay. I get that you are learning. I get that you want to show off. However, you shouldn't just hand people an answer. Feel free to guide others, but let them experiment for themselves.
