Hi,
I´m having problem while converting char to string.
#include "stdafx.h"
#include <fstream>
#include <cstdio>
#include <iostream>
int main()
{
std::ifstream arquivo("entrada.txt");
if (!arquivo)
{
std::cout << "Arquivo não encontrado" << std::endl<< std::endl;
system("PAUSE");
exit(0);
}
std::string token;
char arquivo_linha[255];
while(arquivo)
{
arquivo.getline(arquivo_linha,255);
if (arquivo_linha[0] != 35)
{
token = arquivo_linha;
//std::cout << token << std::endl;
printf("%s\n",token);
}
}
system("PAUSE");
return 0;
}This code only returns <null> on printf, but it works fine if I print the arquivo_linha.
I tried to use arquivo_linha.c_str() but it returns the error:
