Code::Blocks maluco

barutaji · 13 de agosto de 2010

Meu Code::Block(no windows) está muito estranho. Vejam esse código simples que criei:

void asd(double (*)[3], int );

int main()
{ double bla[3][3]={{1,2,3},{1,3,2},{5,6,4}};

    asd(bla,2);

    return 0;
}



void asd(double (*)ar[3], int d){
     double sum=0;


     for(int x=0; x<3; x++){
        for(int y=0; y<3; y++){
           if(d==1)
              sum+=ar[y][x];
           else sum+=ar[x][y];
        }
        for(y=0; y<3; y++){
           if(d==1)
              ar[y][x]/=sum;
           else ar[x][y]/=sum;
        }
        sum=0;
     }
}

Agora veja o resultado tanto do compilador Borland C++5.5 quanto do g++ (chamados diretamente pelo Code::Blocks):

C:\...\main.cpp|13|error: variable or field `asd' declared void|
C:\...\main.cpp|13|error: `int asd' redeclared as different kind of symbol|
C:\...\main.cpp|2|error: previous declaration of `void asd(double (*)[3], int)'|
C:\...\main.cpp|13|error: declaration of `int asd'|

C:\...\main.cpp|13|error: initializer expression list treated as compound expression|
C:\...\main.cpp|13|error: expected `,' or `;' before '{' token|
||=== Build finished: 9 errors, 0 warnings ===|

Obs:troquei o caminho do arquivo por "..." pois é muito longo

"error: declaration of `int asd'"... como?

mas se eu usar o código assim vai tudo certo:

void asd(double **, int );

int main()
{ double bla[3][3]={{1,2,3},{1,3,2},{5,6,4}};
double **bla2;

    bla2[0]=bla[0];
    bla2[1]=bla[1];
    bla2[2]=bla[2];
    asd(bla2,2);

return 0;
}



void asd(double **ar, int d){
     double sum=0;


     for(int x=0; x<3; x++){
        for(int y=0; y<3; y++){
           if(d==1)
              sum+=ar[y][x];
           else sum+=ar[x][y];
        }
        for(int y=0; y<3; y++){
           if(d==1)
              ar[y][x]/=sum;
           else ar[x][y]/=sum;
        }
        sum=0;
     }
}
