C++ Exercises: Create a new string from a given string without the first and last character

C++ Basic Algorithm: Exercise-79 with Solution

Write a C++ program to create a new string from a given string without the first and last character if the first or last characters are 'a' otherwise return the original given string.

Sample Solution:

C++ Code :

#include <iostream>
using namespace std;

string test(string s1)
          {
          if (s1.length() > 0 && s1.substr(s1.length() - 1) == "a")
            {
                s1 = s1.erase(s1.length() - 1);
            }

            if (s1.length() > 0 && s1.substr(0, 1) == "a")
            {
                s1 = s1.erase(0, 1);
            }

            return s1;
          }              
        
int main() 
 {
  cout << test("abcab") << endl;  
  cout << test("python") << endl; 
  cout << test("abcda") << endl;  
  cout << test("jython") << endl;  
  return 0;    
}

Sample Output:

bcab
python
bcd
jython

Previous: Write a C++ program to create a new string from a given string. If the two characters of the given string from its beginning and end are same return the given string without the first two characters otherwise return the original string.
Next: Write a C++ program to create a new string from a given string. If the first or first two characters is 'a', return the string without those 'a' characters otherwise return the original given string.
