Gettting the last character of a string in C++
In this post we will give you information about Gettting the last character of a string in C++. Hear we will give you detail about Gettting the last character of a string in C++And how to use it also give you demo for it if it is necessary.
we are going to learn about how to get the last character of a string in C++.
Consider, we have the following string.
string car = "benz";
Now, we want to get the last character z from the above string.
Getting the last character
To access the last character of a string, we can use the built-in back() function in C++
Here is an example, that gets the last character z from the following string:
#include <iostream>#include <string.h>using namespace std;int main(){ string car = "benz"; char lastCharacter = car.back(); //returns last character cout<< lastChar; return 0;}Output:
"z"
Similarly, we can use the subscript [] syntax by passing string.length()-1 which is the index of a last character.
#include <iostream>#include <string.h>using namespace std;int main(){ string car = "benz"; char lastCharacter= car[car.length()-1]; cout<< lastCharacter; return 0;}Note: The length() function returns the total number of characters in a given string, so we are subtracting it with -1 to get the last character index.
or we can also use the rbegin() function to access the last character of a string like this.
char lastCharacter = *car.rbegin();
Hope this code and post will helped you for implement Gettting the last character of a string in C++. if you need any help or any feedback give it in comment section or you have good idea about this post you can give it comment section.
