Hi. I have a new problem now.
I am using C++ builder 2009 and i cannot make “tmaskedit” to show characters as “*” like in web
Can anyone help me?
Oh thanks it works well.
but can you explain what “cin.get()” means??
and what it used for?and now i have to think how to remove confirmation
thanks it works ok.
now code is12345678910111213141516171819202122232425262728293031323334353637383940414243444546474849505152535455565758596061626364656667686970717273<br />#include <iostream><br />#include <fstream><br />#include <string.h><br />#include <stdlib.h><br />#define MAX_NAME 1000<br /><br /><br />using namespace std;<br />char sendtext;<br />char username;<br /><br />void read(){<br />system("cls");<br />cout << "You autorised as:" << username << "n";<br />ifstream in;<br />in.open("msngr.txt");<br />if (!in) {<br />cout << "Input file cannot be opened.n";<br />//return(1);<br />}<br />char str[20000];<br />while (!in.eof()) {<br />in >> str;<br />cout << str << "n";<br />strcpy(str, "");<br />}<br />cout << "n";<br />in.close();<br /><br />}<br />void write ()<br />{<br /><br />char choice;<br />cout << "do you want to input data to file ( y or n )" << endl;<br />cin >> choice;<br />cin.get(); //get newline<br />while ( choice != 'y' && choice != 'n' )<br />{<br />cout << "bad choice!" << endl;<br />cout << "do you want to input data to file ( y or n )" << endl;<br />cin >> choice;<br />cin.get(); //get newline<br />}<br /><br />if ( choice == 'y' )<br />{<br />char inputText [ MAX_NAME ];<br />cout << "enter input text: " << endl;<br />cin.getline ( inputText , MAX_NAME , 'n' );<br /><br />ofstream outputFile;<br />//PUT YOUR DATA FILE NAME HERE!<br />outputFile.open ( "msngr.txt" , ios::app );<br />outputFile << inputText << endl;<br />outputFile.close();<br />read();<br />write();<br />}<br /><br />}<br />main(){<br />cout << "Enter your username: ";<br />cin >> username;<br />read();<br />write();<br /><br /><br />return (0);<br />}<br /><br /></fstream></iostream>but there is some problems too.
when i enter username it writes only first the letter of the username and all other letters understands as answer to the confirmation and writesYou autorised as:N
do you want to input data to file ( y or n )
bad choice!
do you want to input data to file ( y or n )
bad choice!
do you want to input data to file ( y or n )and when it shows the data of the file it puts n after all words and when i write “something is wrong”
it shows
something
is
wrong
but in file everything is okif ( sendtext )
{
FILE * pFile;
char yazi[] = {sendtext , ‘n’};
pFile = fopen ( “msngr.txt” , “a+” );
fwrite (yazi , 1 , sizeof(yazi) , pFile );
fclose (pFile);
read(); //take these out!
write();
}if i take this out my new text will not appear
i defined MAX_SIZE and this problem solved but now it shows me
invalid conversion from
char’ toconst char*’
initializing argument 2 of `char* strcpy(char*, const char*)’
