why the output only display 1 letter insteed of 1 word after I uppercase
it.
#include<iostream>
#include<fstream>
#include<cctype>
#include<string>
using namespace std;
int main()
{
ifstream in; //input file
string s;
//open in file
in.open("input.txt");
//check to see whether the in file is existing
if (!in)
{
cout<<"Can't not read the file !"<<endl;
in.close();
return -1;
}
getline(in,s,'\0');
cout<<s;
int len=s.length();
char *cs= new char [len+1];
s.copy(cs, len ,0);
cs[len]='\0';
char *tokenptr= strtok(cs, " ");
while(tokenptr != NULL)
{
cout<<(char)toupper(*tokenptr)<<endl;
tokenptr = strtok (NULL, " ");
}
return 0;
}
\\this is I use cout<<s; to display the output of the string
