strlen() c++ code example

Example 1: strlen in cpp

#include <cstring>
#include <cstring>

using namespace std;

int main(void) {
  char stringName[] = "This contains the content of your string";
  int stringLength = strlen(stringName);
  cout << "String: " << stringName << endl << "Length of String: " << stringLength << endl;
  
  return 0;
}

Example 2: structs in c++

#include <bits/stdc++.h>
#include <iostream>

#define ll long long

using namespace std;

struct student{
	int roll;
	string name;
	int age;
	
	void studentDetails(){
		cout<<"Name is "<<name<<" Age is "<<age<<" roll no is "<<roll<<endl;
	}
};


int main(){
	
	student sumant;
	sumant.roll = 30;
	sumant.name = "Sumant Tirkey";
	sumant.age = 18;
	
	sumant.studentDetails();
	cout<<endl;

    return 0;
}

Example 3: strlen in cpp

#include <cstring>
#include <iostream>

using namespace std;

int main()
{
    char str1[] = "This a string";
    
    int len1 = strlen(str1);

    cout << "Length of str1 = " << len1 << endl;

    return 0;
}
