Hello,
I have two codes here. Matlab code is the reference code and I have written this C++ code from that.Don’t worry about the values because i just want to know if the logic of the C++ code is same as MATLAB code coz I am getting some incorrect values as output. However I have declared a few values so that u get some clue of its datatype.
Promptcode, earlycode and latecode each has a random combination of +/- 1’s.
Cacode...

int *x=new int[38200]; is this correct??
Hello,
I have done the following initialization in my C++ code:
int *x=new int[38200];
However a doubt arouse to me now..... int can take values only from 2^15 to (2^15)-1..........So do i have to change it to something like
long int *x=new long int[38200] or is it ok coz its allocating dynamic memory?? If I have to change, then what should it be i.e is my new initialization correct?
Thanks,

Incorrect length output in File read in C++
Hello,
The pgm below opens a file, reads it and displays the contents and its length.
However it displays a length of (length+2) and also the samplesread as (samplesread +2), where samplesread is the length obtaines from gcount(), and length from tellg(). Pls tell me how i should get the correct length and samplesread??. Also if i enter the data in my file in the next line, it considers "\n" towards the length count. Pls correct... -
I am sorry........li ne 39 in my code corresponds to 18 in the above code. i.e the error is in DEFUN_DLD()

struct redeclare problem
hello,
i have a struct and have declared it as shown below. If i print its value in the main() fn it prints it correctly.Howev er if i declare the struct again in the main() and try to print its value it doesnot give me the correct value but prints some garbage value. Why is it so? Is there any way to correct it because i think i have to declare it again in main() for initializing other variables.
thanks,
