String from prefix and suffix of given two strings

Given two strings a and b, form a new string of length l, from these strings by combining the prefix of string a and suffix of string b.

Examples :

Input : string a = remuneration
        string b = acquiesce
        length of pre/suffix(l) = 5
Output :remuniesce

Input : adulation
        obstreperous
        6
Output :adulatperous

How to solve String from prefix and suffix of given two strings:

1. Get first l letters from string a, and last l letters from string b.
2. Combine both results, and this will be the resultant string.

CPP code to form a new string from pre/suffix of given strings.

// CPP code to form new string from
// pre/suffix of given strings.
#include<bits/stdc++.h>
using namespace std;

// Returns a string which contains first l
// characters of 'a' and last l characters of 'b'.
string GetPrefixSuffix(string a, string b, int l)
{
	// Getting prefix of first
	// string of given length
	string prefix = a.substr(0, l);
	
	// length of string b
	int lb = b.length();
	
	// Calculating suffix of second string
	string suffix = b.substr(lb - l);
	
	// Concatenating both prefix and suffix
	return (prefix + suffix);
}

// Driver code
int main()
{
	string a = "remuneration" ,
		b = "acquiesce";
	int l = 5;
	cout << GetPrefixSuffix(a, b, l);
	return 0;
}
