Arrays in C++ An array is a data structure of elements with same data type stored at contiguous memory locations.Arrays are used to store multiple values in a single variable, making it easier to manage large sets of data.
Strings in C++ Strings are sequences of characters used to store text. In C++, the string class is defined in the header file. There are two types of strings in C++ : std : : string
Features:
Iteration: Strings support iterations for traversing thier contents. Concatenation: Strings can be concatenated using the + operator. Indexing: Strings support indexing, allowing access to individual characters using the [] operator. Comparison: Strings can be compared using operators (==, !=, <, >, etc.). Modification: Characters in a string can be modified through direct indexing.
Features :
Fixed size: The size of an array after being defined cannot be changed later. Contiguous memory allocation: All elements are stored in continuous memory blocks. Index-based: Array elements can be accessed using thier indices.
1.Checking Palindrome Input the String: Ask the user to enter a string.
2.Initialize Variables: Store the input string in a variable, a.
Initialize an empty string, revstr.
3.Determine the Length: Calculate the length of a and store it in length.
4.Reverse the String:
Loop from the end of the string to the beginning: Append each character to revstr.
5.Compare the Strings:
Compare the original string a with the reversed revstr. If a == revstr, the string is a palindrome. Else not a palindrome.
6.Output the Result:
Print whether the string is a palindrome or not based on the comparison.
