here is my code, the issue is its not determine if the value is a palindrome or not.

I am trying to check a string to be a palindrome. I have tried using for loop but I am looking for most efficient way.

So I've been tasked with creating a program that checks to see whether or not a string is a palindrome. It has to remove whitespace, punctuation, and capitalization for obvious reasons. Getting some errors which I'm not sure how to correct.
On an unrelated note, while programming in the console, my cursor has turned into a gray box and replaces characters when typing, instead of pushing them forward, etc. How do I return it to normal?

I am trying to create a simple palindrome program. I get the error string subscript out of range. I believe the error is either in the while or for loops.

I am supposed to take the three string lines from a text file and then individually reverse them and state whether or not they are a palindrome. I have the three lines from the text file into string variables already but I am not sure on how to reverse them and then see if they are the same reversed(palindrome)
Here is my code so far -->

I am able to get correct output upto a input of 50000 character string, but not for 100000 character string.
I'm trying to determine the number of times I have to change each specific character in a string to make it a palindrome. You can only change a character one at a time from the end.
Example: "abc" -> "abb" -> "aba" should print 2. "aba" will print 0 because it's already a palindrome. "abcd" -> "abcc" -> "abcb" -> "abca" -> "abba" will print 4 because it took 4 changes to make a palindrome.
I'm not too sure how to approach this - I figured out the case where if it's a palindrome (if reversed string is the same) then it'll print out a 0.
int main() {
int number;
cin >> number; //expecting a number for first line user input
for (int i = 0; i < number; i++) {
string str;

I have an issue with a switch case in my program. I execute it and it does fine all the way up to where it says, "Answer (1, 2, or 3): ". When I enter 1, 2, or 3, it gives me' "Not an input choice!" from the default of the switch case.

I have an assignment for uni which requires the program to ask the user to input a number in for a variable to use in later equations. The assignment specifies that if the number that is input into the program is not an interger that it needs to be rounded UP to the nearest interger. e.g. 2.5 = 3, 5.00001 = 6 etc. i have identified this variable using "int" which i know makes it an interger however it also always rounds the number DOWN to the nearest interger. I was just wondering what the best way to approach this problem was. The only idea i have is to put + 0.99999 at the end of this variable when it is worked out so that if it is not a whole number it will be raised above the next interger and then rounded down however this will not work if there is too many decimal places.

Vector3 position;
};
vector<data> vecData;
or
map<int, pair<ObjectBase *, Vector3>> mapData;

I'm writing a program to read in a Master.txt file and then update it through a Transaction.txt file that contains various transaction types [Adds (A), Deletes (D), and Edits (E1-E4)]. The records in both files are in ascending order based on Item#. Ultimately, the original Master.txt and updated Master file (Master2.txt) will be merged to reflect all valid transactions, and an errorLog.txt file will be created to indicate all invalid transactions. I feel I have all of the code written correctly, but I am still getting errors on my operands and identifiers.
