What I have so far, I need the program to get the string, print out the string in uppercase and then in lowercase and display the number of words and the number of characters

So what you need is a word counting function?

I actually havent added that yet, I havent gotten these to work yet

So what is the problem that has you stumped? The requirements of the assignment are your concern, are they not?

This part confuses me:

lowToUpper(lowerData)
upToLower(upperData)

Don't you want to pass in string[]? If not, then what?

"lowerData" and "upperData" are nowhere in main(), so they can't be passed into these weirdly named functions.

C'mon, if a string doesn't exist in main(), how can you pass it in as a parameter, from main(), to a function called by main()?

You need to get cracking on these problems.

What I was getting at was if you had an actual question. Or if you just wanted us to debug your code without even telling what the problem is.

Code:

/*void codes*/

void lowToUpper(char lowerData[])
     {
                     int i;
                     for (i=0; i<strlen(string); i++)
                     if (isupper(string[i]))
                     string[i]=tolower(string[i]);
     }
     
void upToLower(char upperData[])
     {
                    int i;
                     for (i=0; i<strlen(string); i++)
                     if (islower(string[i]))
                     string[i]=toupper(string[i]); 
     }
int numGraph(char *string)
{
	int i, count = 0;
	for (i = 0; string[i] != '\0';i++)
	{
		if (isgraph((int)string[i])) count++; 
	}
	return count;
}

void getString(char *string)
{
   printf("Please enter a string to process\n");
   fgets(string, STRINGSIZE, stdin);
}

editted, says strings are undeclared in the void types

"string" is not declared in the same scope as these functions, upperData and so on, is on the other hand. Likewise upperData, etc is not declared in main.

You need to replace "upperData" and "lowerData" with "string", or you can't work with the string[] array, in those functions.

If you want to use a copy of string[] in those functions, then you need to declare them (probably inside their functions), and then strcopy(lowerData, string);, to copy the char's over to lowerData (for instance).

Now you can change lowerData[], to all lowercase letters, and leave string[] char's unchanged.

And you're ready to do the same thing for upperData[].

That could work nicely.
