Q. C++ Program to find length of a given string.

Here you will find an algorithm and program in C++ programming language to find length of given string. First let us understand string in C++.

Explanation : The string is defined as an array of characters. The difference between a character array and a string is the string ends with a special character '\0'.

For Example : If the string is "hello", then the output will be 5.

Algorithm to find length of string

Step 1:Length = 0
Step 2: Repeat step 3 while S1 [Length] ≠ NULL
Step 3: Length = Length + 1
Step 4: Return Length

C++ Program to Find the Length of a String

#include <iostream>
using namespace std;
int main()
string str = "Letsfindcourse";
// you can also use str.length()
cout << "Length of the string = " << str.size();
return 0;


Length of the string = 14
