C++ Program to Find the Length of a String
In this example, we will learn to compute the length (size) of a string (both string objects and C-style strings).
To understand this example, you should have the knowledge of the following C++ programming topics:
Introduction
You can get the length of a string object by using a size() function or a length() function.
The size() and length() functions are just synonyms and they both do exactly same thing.
Example 1: Program to Find Length of String Object
#include <iostream>
using namespace std;
int main()
{
string str = "C++ Programming";
// you can also use str.length()
cout << "String Length = " << str.size();
return 0;
}Output
String Length = 15
Example 2: Program to Find Length of C-style string
To get the length of a C-string string, strlen() function is used.
#include <iostream>
#include <cstring>
using namespace std;
int main()
{
char str[] = "C++ Programming is awesome";
// you can also use str.length()
cout << "String Length = " << strlen(str);
return 0;
}Output
String Length = 26

We hope that this Example helped you develop better understanding of the concept of "Find the Length of a Strings" in C++.
