Amigos,

Boa Dia, Desde ontem quando estava dando continuidade ao código que foi declarado para eu tratar me deparei com uma dificuldade enorme,

Eu preciso fazer um código onde ele leia um arquivo .txt linha por linha e sempre que a primeira letra for numero 2 ele vai pular de linha e continuar escrevendo o programa até encontrar novamente o numero 2 e ele pular de linha e assim até o final do programa fazendo o mesmo processo, quando o programa terminar de rodar ele vai armazenar em um outro arquivo .txt já formatado.



Já consegui colocar o arquivo para ler o arquivo e salvar com o auxilio de um amigo daqui mesmo mas eu estou me perdendo na lógica de como colocar a primeira letra da linha ser 2 ela pular já tentei de todas as possibilidades, inclusive de tentar como char mas eu me perco mt . por favor galera alguém poderia me ajudar ?





MEU CÓDIGO



#include <iostream>
#include <fstream>
#include <locale>
using namespace std;

int main() {

setlocale(LC_ALL, "Portuguese");

ifstream arquivo;
ofstream arquivox;
string linha;

arquivo.open("Declan.txt"); // abre arquivo p leitura
arquivox.open("Teste.txt"); // abre arquivo p escrita

if (arquivo.is_open() && arquivox.is_open()) {
while (getline(arquivo, linha)) {
cout << linha; // lê o arquivo linha a linha
if (arquivo, linha) == 2{
arquivox << linha <<endl; // escreve no arquivo

}
}

arquivo.close();
arquivox.close();
} else {
cout << "Não foi possivel abrir o arquivo" << endl;
}

return 0;
}

Caro,

Adicionei o teste com if (linha.at(0) != '2') no seu programa.

#include <iostream>

#include <fstream>

#include <locale>

using namespace std;



int main() {



	setlocale(LC_ALL, "Portuguese");



	ifstream arquivo;

	ofstream arquivox;

	string linha;



	arquivo.open("Declan.txt"); // abre arquivo p leitura

	arquivox.open("Teste.txt"); // abre arquivo p escrita



	if (arquivo.is_open() && arquivox.is_open()) {

		while (getline(arquivo, linha)) {

			cout << linha << endl; // lê o arquivo linha a linha



			//cout << linha.at(0) << endl;

			if (linha.at(0) != '2')

				arquivox << linha <<endl; // escreve no arquivo 

	}



	arquivo.close();

	arquivox.close();

	

	} else {

		cout << "Não foi possivel abrir o arquivo" << endl;

	}



	return 0;

} 

Abraço,
Diego M. Rodrigues

Amigo você poderia em dizer o que foi aquele código que vc comentou o //cout<< ?

Porque assim eu rodei o programa aqui e não notei nada de diferente.

Porque por exemplo eu queria que o programa ia lendo linha por linha quando encontrar o 2 ele pula de linha.

Aquela linha comentada servia apenas para exibir o 1o caractere da linha na tela.

Veja se esse novo programa te atende, alterei apenas o 'if'.

#include <iostream>

#include <fstream>

#include <locale>

using namespace std;



int main() {



	setlocale(LC_ALL, "Portuguese");



	ifstream arquivo;

	ofstream arquivox;

	string linha;



	arquivo.open("Declan.txt"); // abre arquivo p leitura

	arquivox.open("Teste.txt"); // abre arquivo p escrita



	if (arquivo.is_open() && arquivox.is_open()) {

		while (getline(arquivo, linha)) {  // lê o arquivo linha a linha

			cout << linha << endl; 



			if (linha.at(0) != '2')

				arquivox << linha <<endl; // escreve no arquivo 

			else

				arquivox << endl << linha << endl; // escreve no arquivo 

		}



		arquivo.close();

		arquivox.close();

	

	} else {

		cout << "Não foi possivel abrir o arquivo" << endl;

	}



	return 0;

}

Outra forma, mais elegante, com um 'if' apenas para pular a linha no caso do 1o caractere ser um '2'.

#include <iostream>

#include <fstream>

#include <locale>

using namespace std;



int main() {



	setlocale(LC_ALL, "Portuguese");



	ifstream arquivo;

	ofstream arquivox;

	string linha;



	arquivo.open("Declan.txt"); 	// abre arquivo p leitura

	arquivox.open("Teste.txt"); 	// abre arquivo p escrita



	if (arquivo.is_open() && arquivox.is_open()) {

		while (getline(arquivo, linha)) {	// lê o arquivo linha a linha

			cout << linha << endl; 

			

			if (linha.at(0) == '2')

				arquivox << endl;



			arquivox << linha << endl; 

		}



		arquivo.close();

		arquivox.close();

	

	} else {

		cout << "Não foi possivel abrir o arquivo" << endl;

	}



	return 0;

} 

Abraço,
Diego M. Rodrigues

Criei um arquivo chamado Entrada.txt com essa informação que você enviou.
http://www.drsolutions.com.br/vol/18JYT_Entrada.zip

Executei o programa em C++, alterando o nome do arquivo de entrada.
http://www.drsolutions.com.br/vol/18JYT_arquivos.zip

No resultado, apenas na linha
2ANGRA DOS REIS 0000000014
que o programa pulou uma linha, ao enviar para o arquivo de saida, o Teste.txt, já que é a única que começa com 2.
http://www.drsolutions.com.br/vol/18JYT_Teste.zip

O que não está funcionando corretamente?

Você pode me enviar seu arquivo "Declan.txt", ou parte dele, como um zip (diego.m.rodrigues@gmail.com)?

Abraço,
Diego M. Rodrigues
