 |
|
Hello, I'm making a file that writes to a txt file (just for testing), but it only writes the first word of the string 
Here's the script:
| Code: | /* Text File Writer */
/* Includes */
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
/* Function */
int main( void ) {
string writethis;
ofstream write ("input.txt");
if (write.is_open()) {
std::cout << "Write down the output for 'input.txt', please.\n";
std::cin >> writethis;
write << writethis;
write.close();
std::cout << "Done. Press enter to close.";
}
else { cout << "Error: Unable to locate file.\n"; }
std::cin.sync();
std::cin.ignore();
return 0;
}
|
How can I fix this problem?

try std::cin.getline() instead of std::cin .
| Code: | /* Text File Writer */
/* Includes */
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
/* Function */
int main( void ) {
char writethis[256];
ofstream write ("input.txt");
if (write.is_open()) {
std::cout << "Write down the output for 'input.txt', please.\n";
std::cin.getline (writethis,256);
write << writethis;
write.close();
std::cout << "Done. Press enter to close.";
}
else { cout << "Error: Unable to locate file.\n"; }
std::cin.sync();
std::cin.ignore();
return 0;

If you want to get rid of that 256 character limit: | Code: | #include <string>
std::string s;
std::getline(std::cin, s);
file << s; |
