c++ - Why can I pass a string parameter like this? Is this style safe? -

i passing 2 strings 1 parameter in xcode , using c++. tried in xcode , works. safe on platforms?

#include <iostream>  void log_person(const char* name_and_number){     printf("name , number : %s.\n", name_and_number); } int main(int argc, const char * argv[]) {     log_person("jim" "123456789");     return 0; } 

you passing single string. this

"foo" "bar" 

is equivalent to

"foobar" 

so call same as

log_person("jim123456789"); 

this standard c++ , "safe" on conforming implementation. see 2.14.5/13 in c++11 standard:

2.14.5 string literals
