Poxa, finalmente, esse é o primeiro tutorial que funciona..... Muito obrigado.... Acabou, foram 3 dias para configurar isso.....

Bom, eu uso com maior freqüência Linux, tenho alguns programas escritos em GTK+ e C, feitos apenas para Linux. Eu adoraria porta-los para Windows, mas o problema, é que eu não consigo configurar corretamente o GTK+ no Code::Blocks no Windows, creio que teria de alterar pouca coisa para porta-los, no máximo, algumas coisas que usam recursos do sistema, tal como "sleep();". Alguém tem um tutorial que funcione sobre como configurar? Eu já busquei e muito no google e nada funciona. Ele vive dizendo que não encontra o gtk, como resolvo? O único tutorial que chegou perto de funcionar, fez o code::blocks reconhecer os headers, mas não os objetos...... Eu tentei debugar uma simples calculadora após esse tutorial, ocorre um erro como a imagem abaixo mostra : Por favor, me ajudem, eu preciso portar meus aplicativos para Windows.

Como eu queria que Linux, MAC ou Solaris fossem mais usados.....

Depois de tanto sofrer para poder usar o netBeans, foi muito difícil configurar. E isto acontece. /* * File: newmain.cpp * Author: Victor * * Created on 17 de Agosto de 2010, 11:27 */ #include <iostream> using namespace std; /* * */ int main(int argc, char** argv) { cout<<"oi"; cin.get(); cin.get(); return 0; } Da erro "CONSTRUIR FALHOU (valor da saída 1, tempo total: 147ms)" por que isto ocorre no netBeans?????????????

Como os tutoriais não resolveram, eu lhe recomendo 2 livros: use a cabeça - java e java como programar - deitel.

Estou com problemas para aprender a programar interfaces, por favor mandem alguma interface já programada como exemplo.

Esta é fácil. Vou lhe passar a resposta mais analise o código. /* * To change this template, choose Tools | Templates * and open the template in the editor. */ package javaapplication10; import java.util.Scanner; /** * * @author vmf */ public class Main { /** * @param args the command line arguments */ public static void main(String[] args) { Scanner input = new Scanner( System.in ); //permite ler valores float nota1, nota2, nota3_necessaria; System.out.print("digeite a primeira nota"); // lê e armazena a primeira nota nota1=input.nextInt(); System.out.print("digeite a segunda nota"); //lê e armazena a segunda nota nota2=input.nextInt(); nota3_necessaria=210-nota1-nota2; // como a média é 70, a soma das 3 deve ser 210 e este valor menos as 2 primeiras é igual a nota 3 System.out.print("a nota necessária é:"+ nota3_necessaria); // mostra o resultado na tela } // fim do main } // fim da classe

Tenta usar "if" Por exemplo: if (codigo do cliente == 1){ //chame o método para cliente 1 } if(codigo do cliente == 2){ //Chame o método para cliente especial } if(codigo do cliente >=2){ System.out.print("erro, entre apenas 1 ou 2"); // chame novamente o método main para ler novamente ou reinicie o programa }

Tem como aparecer este tipo de caractere em C++? Eu digito "cout<<"o valor é:"<<valor;" porêm o resultado na tela é diferente. A questão é tem como usa-los no "cout" e em variáveis do tipo array?
