problema conversão/soma binários

Recommended Posts

 

Eu estou com o seguinte problema: receber dois números decimais e convertê-los para binário e depois realizar a soma binaria dos números que foi convertidos (considerar números negativos). Eu consegui fazer a maior parte, mas a soma esta saindo errada. Quem puder me ajudar eu agradeço.
Segue o código do programa ate agora:

#include <stdio.h>
#define na 16
int main() {
 int n,n1,r[na],r1[na],i,somav[na],vaium=0,invert[na],np=1;

 /*Lê o número*/
 printf("\n Digite o primeiro numero: ");
 scanf("%d", &n);
 /* Utiliza um número de 16 bits como base para a conversão.*/
 for(i = na-1; i >= 0; i--) {
    r[i] = (n >> i) & 1;
    /*Por meio do "e" lógico ele compara se o valor na posição mais à direita é 1 ou 0 e imprime na tela até reproduzir o número binário.*/
    if(r[i] & 1)
        printf("1",r[i]);
     else
        printf("0",r[i]);

 }
 printf("\n Digite o segundo numero: ");
 scanf("%d", &n1);
 for(i = na-1; i >= 0; i--) {
    r1[i] = (n1 >> i) & 1;
    if(r1[i] & 1)
        printf("1",r1[i]);
     else
        printf("0",r1[i]);

 }
/*for (i=na-1;i>=0;i--)
    vaium[i]=0;*/
if(n<0) {
   for(i=na-1;i>=0;i--){
        if(r[i]==1)
            invert[i]=0;
        else
            if(r[i]==0)
                invert[i]=1;
    }
    for (i=na-1;i>=0;i--)
        r[i]=invert[i]+np+vaium;
        if(r[i]==2){
            r[i]=0;
            vaium++;
        }
}
else
    if(n1<0){
        for(i=na-1;i>=0;i--){
        if(r1[i]==1)
            invert[i]=0;
        else
            if(r1[i]==0)
                invert[i]=1;
    }
    for (i=na-1;i>=0;i--)
        r1[i]=invert[i]+np+vaium;
        if(r1[i]==2){
            r1[i]=0;
             vaium++;
        }
}

for(i=na-1;i>=0;i--){
    somav[i]=r[i]+r1[i]+vaium;
    if((somav[i]==2) || (somav[i]==3)){
        somav[i]=0;
        vaium++;
    }
}
printf("\n Soma dos numeros binarios:");
for (i=na-1;i>=0;i--)
    printf("%d",somav[i]%2);
 return 0;
}

      Quando eu tento acessar a minha máquina pelo ip em outro computador eu me deparo com o erro 403 forbidden
      You don't have permission to access / on this server.
       
      O meu arquivo httpd.conf  está assim:
       
      # # This is the main Apache HTTP server configuration file. It contains the # configuration directives that give the server its instructions. # See <URL:http://httpd.apache.org/docs/2.4/> for detailed information. # In particular, see # <URL:http://httpd.apache.org/docs/2.4/mod/directives.html> # for a discussion of each configuration directive. # # Do NOT simply read the instructions in here without understanding # what they do. They're here only as hints or reminders. If you are unsure # consult the online docs. You have been warned. # # Configuration and logfile names: If the filenames you specify for many # of the server's control files begin with "/" (or "drive:/" for Win32), the # server will use that explicit path. If the filenames do *not* begin # with "/", the value of ServerRoot is prepended -- so "logs/access_log" # with ServerRoot set to "/usr/local/apache2" will be interpreted by the # server as "/usr/local/apache2/logs/access_log", whereas "/logs/access_log" # will be interpreted as '/logs/access_log'. # # NOTE: Where filenames are specified, you must use forward slashes # instead of backslashes (e.g., "c:/apache" instead of "c:\apache"). # If a drive letter is omitted, the drive on which httpd.exe is located # will be used by default. It is recommended that you always supply # an explicit drive letter in absolute paths to avoid confusion. ServerSignature On ServerTokens Full # # ServerRoot: The top of the directory tree under which the server's # configuration, error, and log files are kept. # # Do not add a slash at the end of the directory path. If you point # ServerRoot at a non-local disk, be sure to specify a local disk on the # Mutex directive, if file-based mutexes are used. If you wish to share the # same ServerRoot for multiple httpd daemons, you will need to change at # least PidFile. # # Apache variable names used by Apache conf files: # The names and contents of variables: # APACHE24, VERSION_APACHE, INSTALL_DIR, APACHE_DIR # should never be changed. Define APACHE24 Apache2.4 Define VERSION_APACHE 2.4.33 Define INSTALL_DIR c:/wamp Define APACHE_DIR ${INSTALL_DIR}/bin/apache/apache${VERSION_APACHE} ServerRoot "${APACHE_DIR}" # # Mutex: Allows you to set the mutex mechanism and mutex file directory # for individual mutexes, or change the global defaults # # Uncomment and change the directory if mutexes are file-based and the default # mutex file directory is not on a local disk or is not appropriate for some # other reason. # # Mutex default:logs # # Listen: Allows you to bind Apache to specific IP addresses and/or # ports, instead of the default. See also the <VirtualHost> # directive. # # Change this to Listen on specific IP addresses as shown below to # prevent Apache from glomming onto all bound IP addresses. # #Listen 12.34.56.78:80 Listen

      Olá! Preciso de ajuda no seguinte: farei uma árvore-b para apresentar um trabalho na faculdade, que consiste em ler os dados de um arquivo de texto e passá-los para a B tree. Farei da seguinte maneira: Criei um struct com os tipos de dados (Lote; Placa; UF; Motor; Renavam; Chassi; Ano; Marca/ Modelo; Proprietário; Financeira; Valor) e vou armazenar o Lote na B-tree e, então, quando pesquisarem pelo lote, exibirei os dados do struct relacionados ao lote. A questão agora é como ler o arquivo de texto, pois não estou conseguindo ler e armazenar as informações em suas respectivas variáveis. Segue como o arquivo está.
