COMPARING float arrays and string arrays

[juancafe2]

Hey there I have to do a merge sort program which i have to compare two float arrays setting = and also string arrays

Can somebody explain me how do I compare them

void person::mergeFloat ( double *a[], int end1, int end2)
{
	int i = 0;
	int j = end2;
	int k = 0;

	double *temp = new double [end2];

	// Take each next smallest element

	while (i < end1 && j < end2)
	{
		if(a[i] < a[j])
		{
	
			double temp [k] = a[i];
		}
	}
}

void mergeString(string *a[], int end1, int end2)
{
	int i = 0;
	int j = end1;
	int k = 0;

	string *temp = new string [end2];

	while (i < end1 && j < end2)
	{
		if(a[i] < a[j])
		{
	
		float temp[k] =  a[i];
		}
	}
}
