Remove consecutive duplicate characters in a string

Here given code implementation process.

//C Program
//Remove consecutive duplicate characters in a string
#include <stdio.h>

//Remove all consecutive repeating characters from the string
void remove_consecutive(char * text, int size)
{
	if (size <= 0)
	{
		return;
	}
	printf("\nBefore : %s", text);
	int index = 0;
	int i = 1;
	for (i = 1; i < size; ++i)
	{
		if (text[i] != text[index])
		{
			// When are no consecutive repeating characters
			index++;
			text[index] = text[i];
		}
	}
	if (index != 0 && (index + 1) < size)
	{
		// When needed to add a null character
		text[index + 1] = '\0';
	}
	printf("\n");
}
int main()
{
	//Define the character elements
	char text[] = "codexxxyyyzzzzz";
	//Get the size
	int size = sizeof(text) / sizeof(text[0]) - 1;
	remove_consecutive(text, size);
	printf("After : %s", text);
	// Other cases
	char text1[] = "wwwrronnngcooooooodeeteeest";
	size = sizeof(text1) / sizeof(text1[0]) - 1;
	remove_consecutive(text1, size);
	printf("After : %s", text1);
	return 0;
}
