Capitalize letter in string to output... Should be a pretty easy solution!

[nelledawg]

Hi guys,

Okay so this time I need help with string input. I have the whole program (yet again) but I just need to figure out how to change letters of user input to redisplay them. The code is below and it asks the user to input the product description. I would like to take the product description and capitalize the first letter of each word they type in, so I can redisplay it that way in the summary. The only thing is that I'm not allowed to use the strupr() function... I have to write my own... Otherwise I would have this done! Please let me know if you can help!

>>capitalize the first letter of each word they type in,
One way to do it would be to use strtok() to find each work then toupper() to change the first character to upper case. strtok() modifies the original string so you will want to make a copy of the string before doing anything with it.

[jephthah]

strtok will work to be sure, but you have to watch out that it will stomp all over your original string.

another way is to use pointers. make sure you can understand, and explain, how this works

void capitalizeFirsts(char *buf)
{
    *buf=toupper(*buf);            // first char CAP
    while (*buf++ != '\0')
        if (*buf == ' ')           // look for space
            *buf=toupper(*++buf);  // CAP next char
}

[jephthah]

call it from anywhere you want to.

if you have any string, lets call it "myString", and it has a bunch of text in it, when you make this call

captializeFirsts(myString);

after the function comes back, all the first characters in each word within "myString" will be capitalized.

if there's only one word in "myString", only the first letter of that word will be capitalized. if theres a hundred word, each of the hundred words will be capitalized.

[Ancient Dragon]

Hummmm. Seems your function needs a tad bit more work. But its close.

int main()
{
    char str[] = "now \tis     the   time  for   all    good    men\n";
    capitalizeFirsts(str);
    puts(str);
    return 0;
}

Results

Now     is     The   Time  for   All    good    men

Press any key to continue . . .

Alright, I'm still totally confused. I don't know where that is supposed to go since it is getting the string from user input during multiple functions. Here is what I have and every time I run it as soon as I enter the description it asks for the quantity then automatically says I entered an incorrect quantity, and it just keeps repeating that over and over.

[jephthah]

your "getstring" function is buggering things up. your have a redeclaration for prodscrip that is local to that function, so when it returns back to "main( )" there's nothing for it to use, and you overrun the buffer.

"fprint" and "gets" work nice enough, i dont see what the benefit is for a separate function anyhow. you should always avoid scanf() whenever possible.

from your main( ) routine, remove the line

getstring(prodscrip,"product description");

and replace it with

printf("Enter the product description : ");
gets(prodscrip);

that will work.

[nelledawg]

I add that but then it still doesn't capitalize the first letter of each word inputted. What am I missing? I think I have to call the firstUpper() function after the gets(prodscrip) part, right?

[jephthah]

your program, as posted in #7, with the changes i call in #8, is working just fine for me.

other than the fact i had to comment out #include lab7.h ... im using exactly what you posted.

EDIT:

i see what you did. in your latest program you removed the lines:

firstUpper(prodscrip);
puts(prodscrip);

just curious, how much help did you have writing the rest of the program? did you write it yourself?

[jephthah]

Hummmm. Seems your function needs a tad bit more work. But its close.

int main()
{
    char str[] = "now \tis     the   time  for   all    good    men\n";
    capitalizeFirsts(str);
    puts(str);
    return 0;
}

Results

Now     is     The   Time  for   All    good    men

Press any key to continue . . .

good catch :P

i only planned for single spaces between words. as it happens, the function handles odd number of spaces, but not even number.

change the function to this, and it should be nearly bulletproof:

void capitalizeAll(char *buf)
{
	int capNext = 0;

	*buf=toupper(*buf);
	while (*buf++ != '\0')
	{
		if (capNext)
		{
			*buf=toupper(*buf);
			capNext = 0;
		}
		if (*buf <= ' ')
			capNext=1;
	}
}

[nelledawg]

Sorry, I should have let you know I actually got it riiiight after I posted last time. Thanks a lot for your help!

As far as writing the program goes, it's for my C Programming Class and it has been written and modified over the course of 6 lab assignments. I wrote it all myself, but each week I usually have some small problem and I put it on here to get some help. Other than that, I've gotten no other help.

[Ancient Dragon]

Another version

void capitalizeFirsts(char *buf)
{
    while( *buf )
    {
        while( isspace(*buf) )
            buf++;
        *buf = toupper(*buf);
        while(*buf && !isspace(*buf))
            buf++;
    }
}

[jephthah]

^ that works better than my first attempt, and much more elegant than my second.

nice job
