using namespace std;
int main()
{
    char name[20];
    int a;
    cout << "Enter your name : ";
    cin.getline(name,20);
    int len = 0;
    for (a = 0; name[a] != '\0'; a++)
    {
        len++;
    }
    cout << "Length of the string is: " << len;
    return 0;

Length of the string is: 15

Note: gets() function is an alternative to getline(), but it is prone to buffer overflow issues.
