c sharp1min read In this tutorial, we are going to learn about how to get the last character of a string in C#. Consider, we have the following string. string str = "piano"; Now, we want to get the last character o from the above string. Getting the last character To access the...
Lastly, it prints the modified string after removing the last character. Code Snippet: #include<iostream>using namespace std;intmain(){string str;cin>>str;cout<<"Original String: "<<str<<endl;str.erase(str.size()-1,1);cout<<"Required String: "<<str<<endl;return0;} ...

. . This code uses the MBCS functions _mbsrchr and _mbsinc. Because these functions are MBCS-aware, they can distinguish between a '\' character and a trail byte '\'. The code performs some action if the last character in the string is a null ('\0')....
The strlen() function returns the total number of characters in a given string. Here is an example, that gets the last characterefrom the following string: #include<stdio.h>#include<string.h>intmain(){charfruit[5]="apple";printf("Last character : %c",fruit[strlen(fruit)-1]);} ...
/* If the first and last character of the string aren't the same, * the string cannot be a palindrome. */ else if (text[0] != text[text.length() - 1]) { return false; } /* Otherwise, this string is a palindrome precisely when the middle ...
