Write a C++ Program to Find String Length with an example. This programming language has a length function to find the string characters.
#include<iostream> #include<string> using namespace std; int main() { string txt; cout << "\nPlease Enter the String to find Length = "; getline(cin, txt); int len = txt.length(); cout<< "\nThe Length of '" << txt << "' String = " << len; return 0; }

In this C++ language, there is a size function that returns the length of a string. Please refer to C++ programs.
#include<iostream> #include<string> using namespace std; int main() { string txt; cout << "\nPlease Enter the Text = "; getline(cin, txt); int len = txt.size(); cout<< "\nThe Length of '" << txt << "' = " << len; return 0; }
Please Enter the Text = hello world
The Length of 'hello world' = 11
C++ Program to Find String Length using a While loop
#include<iostream> #include<string> using namespace std; int main() { string txt; cout << "\nPlease Enter the Text = "; getline(cin, txt); int i = 0; while(txt[i]) { i++; } cout<< "\nThe Length of '" << txt << "' = " << i; return 0; }
Please Enter the Text = c++ programming
The Length of 'c++ programming' = 15
This C++ Program Finds the total number of String characters using For loop
#include<iostream> #include<string> using namespace std; int main() { string txt; int i; cout << "\nPlease Enter the text = "; getline(cin, txt); for (i = 0; txt[i]; i++); cout<< "\nThe Length of " << txt << " = " << i; return 0; }
Please Enter the Text = hello world!
The Length of 'hello world!' = 12
