How can I display a string using c++?

Hy,

 

Suppose you want to open a text file through the C++, then you need to use bellows script or source :

 

intmain()

{     std::wfstream myfile("C:\Users\nirob\Documents\mytext.txt");     

if(!myfile.is_open()

)     

{std::cout <<"error"<<std::endl;    

 }   

  else     

{         std::cout <<"opened"<<std::endl;     

}     std::wstring mystring;     myfile >>mystring; 

    std::wcout <<mystring <<std::endl;     system("PAUSE"); 

}

 

There I tried to open a text document which directory is ("C:\Users\nirob\Documents\mytext.txt” , So at first you should keep your text file in a folder then just put the directory in your C++ source or script. Then use above code for call any text file in your script.  That’s a easy process to open any text file by that C++ source.

 

Suppose  you want to open a variable string in C++, then you should create your own source 

by the help of  bellows source or code :

 

string vers ="v. ";

 vers +=maj_vers;// + 50;  vers +=".";  

vers +=min_vers;// + 50;  vers +=".";  

vers +=patch_vers;// + 50; 

constchar*pvers =vers.c_str();  

mvaddstr(7,19,pvers);  refresh();

 

Thanks.

How can I display a string using c++?

Hello Mia Walker,

As you said you are newbie so 1st you should have to learn about strings.

String is character arrays. like "char arr[50];" is a string. To display it we have a different method.

1st method:

use for loop:

for(int i=0;i<50;i++)

{

cout<<arr[i];

}

this is a lengthy method.

2nd method:

use string.h library,

and just write string name in

puts(arr);

this will also print the same thing.
