Two ways to define a string array

Two ways to implement a string array in C + +

1, the common method

#include <iostream>#include<string>using namespacestd;intMain () {stringstr[]={"Hello","string"," World"}; intStr_size=sizeof(str)/sizeof(string); cout<<"size of Str is"<<str_size<<Endl;  for(intI=0; i<str_size;++i) cout<<str[i]<<Endl;}

2. Methods of using pointers

#include <iostream>using namespacestd;intMain () {Char*a[] = {"Hello","string"," World" }; intA_size =sizeof(a)/sizeof(Char*); cout<< a_size <<Endl;  for(inti =0; i<a_size; i++) cout<< * (a+i) <<Endl; return 0;}
