Find the Length of a String:

Overview

Although the C ++ language does not have a specific operator for dealing with strings, it does have many library functions that allow you to perform a variety of actions on strings, for example strlen. You may have heard of the use of. In addition to this, there are many other functions by the name of which the work is known. Today, the library function that I will mention in Tania kodlogs is strlen function. This function can be any string. Counts the number of characters in. There is another similar function called xstrlen () function. This function is very simple. In fact, its function is to count the number of characters in a string from beginning to end. Until the null character appears. The character pointer is used to create this function.

Strlen method:

So first let's try to understand the function of strlen. This function tells the length of the letters in any string. With the help of this function we set the working limit or condition of the for loop. But remember that this function does not count the null character in its number.

Flowchart:

syntax.
Lenght = Strlen (name);

Methods to find length of string:
1.string::size
2.string::length
3.While loop
4.For loop
5.Strlen method

Let's have some create programs that will count the number of characters in any string.

1.String length function:

string txt = "Wellcometokodlogs";
cout << "Length of string is: " << txt.length();

OUTPUT 
17

2.String size function:

string txt = "Wellcometokodlogs";
cout << "Length of string is: " << txt.size();

OUTPUT 
17

3.String strlen function:

#include <iostream>
using namespace std;

int main() {
    string str = "Wellcometokodlogswebsite";

    // you can also use str.length()
    cout << "String Length = " << str.size();

    return 0;
}
OUTPUT 
String Length:24

Summary :
Today we understand kodlog website, I try to explain the C++ get size of strings . I hope after reading this article you will be able to understand the size & length of string. I would like to have feedback from my kodlog site. Please post your feedback, question, or comments about this article.
