len of char array c++ code example

Example 1: c++ length of char array

char* example = "Lorem ipsum dolor sit amet";
int length = strlen(example);
std::cout << length << '\n'; // 26

Example 2: c++ length of char*

#include <iostream>
#include <string.h>

using namespace std;

int main()
{
    char *str = "ABC";
    cout << strlen(str) << endl;
    return 0;
}

Example 3: how to find length of character array in c++

#include <iostream>

using namespace std;

int main()
{
    char arr[] = "grepper";
    cout << sizeof(arr) << endl;
    return 0;
    //    keep it in mind that character arrays have length of one more than your characters because last one is for \0 to show that word has ended
}

Example 4: char size length c++

char* a = "ABC";
int length = sizeof(a)/sizeof(char);
