I try to enter names but anytime it will teat them as separate strings.

But i was getting segmentation faults,
can you figure anyway out.

===== PURPOSE : A function that concatenate 2 words entered from console. =====

//===== START OF CODING =====


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

//===== PROTOTYPE FOR MYSTRCAT FUNCTION =====

void mystrcat (char a[], char b[]);

//===== start of main code : 

main()

{
	//declaring character arrays:

	char word1 [200]; 
	char word2 [50]; 

	//accepting  and reading word from console : 

	printf("\n\nEnter first word : ");
	scanf("%s", word1);

	printf("\n\nEnter second word : ");
	scanf("%s", word2);

	mystrcat (word1, word2);

	//printf("\n\nEnter third word : ");
	//scanf("%s", word3);

	//calling the mystrcat function in the main function :

/*	new = strcat (word1, " ");
	new1 = strcat (new, word2);
	new2 = strcat (new1, " ");
	new3 = strcat (new2, word3);

	printf("\n\nthe word is %s\n\n", new3);*/	
}

//===== START OF CODING THE MYSTRCAT FUNCTION :

void mystrcat (char a [], char b [])
{

	//declaring int variables to store the length of the arrays :

	int i, l1, l2;

	//detecting length of arrays and passing them to a variables :

	l1 = strlen (a);
	l2 = strlen (b);

	//looping through the word2 so it can be add to the first word:

	a[l1+i] = 0;

	for (i = 0; i <= l2; i++)
	{
		a[l1+i] = b[i];
	}

	// sentence to display to console :

	printf("\n\nThe concatenated word is %s\n\n", a);
}

//===== END OF CODING THE MYSTRCAT FUNCTION =====

Do you want to actually post the code with regards as to what you want to do? It's blank!

> a[l1+i] = 0;
You didn't initialise i
That means boom today (or boom tomorrow if you're unfortunate)
