Help with txt file importing to c++

[victorfc]

Hi ppl, I'm trying to import a txt file using c++, so I created a class file to make it easier. Anyway, it's not easy, I cannot make it work!!
I'm using mac xcode and Codeblocks for windows.
Can anyone help me?

The txt file have 60 lines, "char char float float" each, I want my program to return some of these lines.
Thank you all!!

    char **Marca, **Modelo;

    int tamanho;

    fstream File;

    File.open(Nome);    //file.open

    int i = 0;
    while( File )

        File >> buf;
        char *str = new char [strlen(buf)+1];
        memcpy(str, buf, strlen(buf)+1);

I'm trying to make it easier now, making all part of a main function, but still not working =/

#include <iostream>
#include <fstream>
#include <cmath>

using namespace std;

int main()
{


    float a, b, l, p_cc, m_se,p_l, r_tc, k_tc, m_cv_max;
    char marca[61], modelo[61];
    int kcv[61], mcv[61];

    //ENTRADA DE VARIAVEIS
    a=1.16;
    b=0.87;
    l=11.5;
    p_cc=696;
    m_se=1450;
    p_l=780;


    r_tc=((l-2)/(2*l-8))*l*(p_cc+acos(-1)*a*b*p_l);         //CALCULO DE Rtc

    k_tc=((l-6)/(2*l-8))*l*(p_cc+acos(-1)*a*b*p_l);         //CALCULO DE Ktc

    m_cv_max=48500-(k_tc+r_tc+m_se);                        //CALCULO DE Mcv,max

    cout<<"Mcv,max: "<<m_cv_max<<endl;

   ifstream file ("cavalos-mecanicos.txt");
   if (file.is_open())
   {
       cout<<endl<<"Arquivo Aberto."<<endl<<endl;

            for (int i=0; i<61; ++i){

            file>>marca[i]>>modelo[i]>>kcv[i]>>mcv[i];

            if ((kcv[i]>=k_tc) && (mcv[i]<=m_cv_max)){
            float sumdif=(kcv[i]-k_tc)+(m_cv_max-mcv[i]);
            cout<<marca[i]<<"\t"<<modelo[i]<<"\t"<<kcv[i]<<"\t"<<mcv[i]<<"\t"<<sumdif<<endl;

            ++i;
            }
        }
   }

    return 0;

}

Someone?!
