New style (c to c++)

pedromenezes

Hi Guys,

How to correct this to the new style?

   int i, n = (int)strtol(argv[1], nullptr, 10); // here
      n = n/2;
      double s = strtod(argv[2], nullptr);
      double f = strtod(argv[3], nullptr);
      double a = tan(M_PI*f/s);
      double a2 = a*a;
      double r;
      double *A = (double *)malloc(n*sizeof(double)); //here
      double *d1 = (double *)malloc(n*sizeof(double)); //here
      double *d2 = (double *)malloc(n*sizeof(double)); //here
      double *w0 = (double *)calloc(n, sizeof(double)); //here

Cheers

What do you mean with 'new style'? Do you mean using c++ (c++11/14/17) or Qt functions instead?

@pedromenezes said in New style:

int i, n = (int)strtol(argv[1], nullptr, 10); // here

Use QString::toInt() or QByteArray::toInt()

  double *A = (double *)malloc(n*sizeof(double)); //here
  double *d1 = (double *)malloc(n*sizeof(double)); //here
  double *d2 = (double *)malloc(n*sizeof(double)); //here
  double *w0 = (double *)calloc(n, sizeof(double)); //here

Use QVector<double> or std::vector<double>

@Christian-Ehrlicher Sorry, I mean c to c++.

@JKSH thank you!! Problem solved!
