C++ Exercises: Create a new string from a given string without the first and last character
Remove First/Last 'a' or Return Original
Write a C++ program to create a string from a given string without the first and last character. This is possible if the first or last characters are 'a' otherwise return the original given string.
Sample Solution:
C++ Code :
#include <iostream> // Including the input/output stream library
using namespace std; // Using the standard namespace
// Function that modifies the input string by removing 'a' from the beginning or end
string test(string s1)
{
// Check if the length of s1 is greater than 0 and the last character is 'a'
if (s1.length() > 0 && s1.substr(s1.length() - 1) == "a")
{
s1 = s1.erase(s1.length() - 1); // Remove the last character from s1
}
// Check if the length of s1 is greater than 0 and the first character is 'a'
if (s1.length() > 0 && s1.substr(0, 1) == "a")
{
s1 = s1.erase(0, 1); // Remove the first character from s1
}
return s1; // Return the modified string
}
// Main function
int main()
{
cout << test("abcab") << endl; // Output for "abcab"
cout << test("python") << endl; // Output for "python"
cout << test("abcda") << endl; // Output for "abcd"
cout << test("jython") << endl; // Output for "jython"
return 0; // Return statement indicating successful termination of the program
}
Sample Output:
bcab python bcd jython

For more Practice: Solve these Related Problems:
- Write a C++ program to remove the first and/or last character from a string if they are 'a'; otherwise, return the string unchanged.
- Write a C++ program that reads a string and trims the character 'a' from the beginning and/or end if present, printing the result.
- Write a C++ program to check the first and last characters of a string for 'a' and remove them if found, else return the original string.
- Write a C++ program that conditionally strips 'a' from the boundaries of a string and outputs the modified string only when applicable.
Go to:
PREV : Remove First Two Characters if Start = End.
NEXT : Remove First/First Two 'a's if Present.
