who developed c++ and when?

c++ is a language based on

#include <iostream>

#include <cstring>

using namespace std;

int main() {

char n[10];

char x[20];

x[0] = '\0';

strcat(n,"\0");

strcat(n,"0123456");

strcat(n,x);

strcat(n,x);

cout << strlen(n);

}

what will be output

#include <iostream>

#include <cstring>

using namespace std;

int main() {

char n[11];

char x[20];

x[0] = '\0';

strcat(n,"\0");

strcat(n,"012345698");

strcat(n,x);

strcat(n,x);

cout << strlen(n);

}
