how can deal with array result

[sean_tan]

I use cvi  write a dll,it should be return the result as below:

   7.47854E-2,7.47854E-2,7.47854E-2,7.47854E-2,7.47854E-2,7.52150E-2,7.47854E-2,7.52150E-2,7.52150E-2,7.52150E-2,7.47854E-2

how can I deal with it like this:

  a[0]= 7.47854E-2

  a[1]=7.47854E-2

and so on,thanks

Hi，
What is the data type of that returned result? Is it a string or an array?
Maybe you have to make this tranformation manually.

Looks like a string of readings in ASCII coming from an instrument like a 34970A multimeter or similar.

You can get the  readings into a string (array of char with trailing NUL (0)), then use strtok function in C standard library with "," token to parse the string into substrings that you can then scan with something like  

double dReading;

char * szValue;

for (int i = 1, I <= numreadings; i++) {

  if (i == 1) {

    szValue = strtok (szReadings, ",");

  }

  else {

    szValue = strtok (NULL, ",");

  }

   sscanf (szReading, "%lf", &myArray[i-1]);

}  // end, for

The smiley faces are supposed to be closing parentheses , and the for statement should be

for (int i = 1; i <= numReadings; i++)

 and I'm assuming the use of C99 extension allowing the declaration of ablock scope variable other than at the beginning of the block.

or just query the instrument for one reading at a time and fill the array that way.
