Arrays as function arguments :(

Hi All!!!

My task is...
"Write a function that adds the elements of two one-dimensional arrays of same size. The results should be stored in a third function. The function should take as arguments the name of the three arrays and the array dimensions.

Write a simple program that uses the function. The two arrays should be declared at the beginning of the program (in the main function block)"

This is my code so far...

Code:

#define _CRT_SECURE_NO_DEPRECATE

#include<stdio.h>
#include<string.h>

main()
{
	char first[31];   
	char second[31];   
	char name[62];	  

	
	printf("Please enter your first name(s): ");
	scanf("%[^\n]", first);
	printf("Please enter you surname(s): ");
	fflush(stdin);
	scanf("%[^\n]", second);

	
	strcpy(name, first);
	strcat(name, " ");
	strcat(name, second);

	
	printf("Your full name is %s", name);
	
}

I have tried for ages but I cannot arrange my code in to the specified function as the task requires.

Can anyone please help??

Thanks in advance

1) Don't double post, add to the original thread.
2)

Code:

#define _CRT_SECURE_NO_DEPRECATE

Isn't used.
3)

Code:

fflush(stdin);

Look at the FAQ as for why this is wrong.
4) Give the function a try and then post your function's code.

yeah sorry! i realised i made a new thread - new to message boards

ive been working on this and a couple of other problems all day m8 - cut me some slack. ive tried 2 get this in 2 a function that many times you wudnt believe it! i really need 2 learn and practice functions but i just dnt get it when u pass arrays - my code never seems 2 compile. u guys r my last resort.

So show us your tries!

Code:

#include<stdio.h>
#include<string.h>

main()
{
	char first[31];   
	char second[31];   

	printf("Please enter your first name(s): ");
	scanf("%[^\n]", first);
	printf("Please enter you surname(s): ");
	fflush(stdin);
	scanf("%[^\n]", second);

add(first, second);
	
}
add(char first, char second)
{
	char name[62];	 

	strcpy(name, first);
	strcat(name, " ");
	strcat(name, second);	

	printf("Your full name is %s", name);
}

this try actually will compile - it does so with errors and also crashes when you run it - i dunno wats wrong

Can anyone help please?

Didn't we already do this here?
Arrays as function arguments!

You're still flushing stdin...a definite no-no. Other, than that, well, I think you want add to be :

Code:

add(char* first, char* second)

Lastly, prototype your functions. That should get rid of some warnings/errors.

Dear Salem

I looked at your guidance for the other source code and tried to apply the same general setting for this code but this particular piece of code crashes on me.

Ive been trying to fix it for ages, just cant seem to get it to work. atleast, i can get it to work but not how the question asks for it.

what do i write instead of fflush then to flush the keyboard???

otherwise, if i leave it out - the program makes up its own random names after the first string variable has been typed in.

But apparently, the "copy/paste" rule seems to have evaded your attention span.

char first[31];
char second[31];

followed by
add(first, second);

followed by
add(char first, char second) // How is this a copy/paste of the arrays you're passing???


FYI
void foo ( char array[SIZE] );
void foo ( char array[ ] );
void foo ( char *array );
are all equivalent.

ohhhh okay! nice 1 ppl!!
thanks 4 help
