Length of the string ?

- 
#include <iostream>
using namespace std ;
//Instead of using length functon you can use a inbuilt function called 'strlen' but if you want to
//use it then you must include <cstring> library. Program will become lot easier.
int length(char input[]) {
    int count{0};
    for (int i = 0; input[i] != '\0'; ++i) {
        count ++ ;

    }
    return count ;


}

int main(){
    char name[100] ;
    cout << "Enter your name :" ;
    cin >> name ;
    cout << length(name);

    return 0 ;
}

  // # CODE: TREE2 // first line of input contains the testcases // next line contains number of sticks (n) and the next line // contains height of the sticks // logic: // we input the heights of sticks into a list (sticks) // then we extract all the unique elements of the sticks // and append them to a new list (uniqueHeight) the length // of the unique list will be number of passes required to // cut the sticks because the number of passes will be equal // to the number of unique elements in the list.
