Merging of arrays

[dontknow]

Hello, I have 2 arrays unsorted, and I need to merge them together and then sorted. But I really don´t know, how to do it. Could you please help me? Thanks.

//Array 1:
int i=0; 
int *array=new int[14];
int y = 14;
int x = 0;
ifstream in("somefile.txt", ios::in |ios::binary); 
while(in >> array[x] && x < y)
{x++;}
for(i = 0; i < 14; i++)
{ cout << array[i] << endl;}

//Array 2:
int j=0; 
int *arra=new int[14];
int z = 14;
int h = 0;
ifstream in("somefile2.txt", ios::in |ios::binary); 
while(in >> arra[h] && h < z)
{h++;}
for(j = 0; j < 14; j++)
{ cout << arra[j] << endl;}

Sorting

The topic of sorting in computer science is considerable and there are many different methods on how to best sort an array in terms of speed and memory. The wikipedia article (below) provides generic details and psuedocode on many of the sorting algorithms that are in use today. I would begin by looking over the article and picking one that you think you can implement.

I think that you would need to sort each container before merging

Are you guaranteed to get the same length of elements in both arrays?

Either way, since you have two seperate arrays already, sort them seperately before merging them for better efficiency.

Given that a string is an array:

string s="12487369";
string s2="59214603";
s3=s+s2="1248736959214603";
sort(s3);
s3="0112233445667899";

//now convert s3 to integers using atoi() inside a for loop with its condition specified in terms of s3.length().
