I wanted to read float values from file(count of values is not known)& assign to different variables in my MFC dialogue based application.I do s many try,but it retrieves only one value from value!!
How to do that?
First Try ony retrieves fist value

fscanf(fp,"%0.20f\t",&t21);
fscanf(fp,"%0.20f\t",&t31);

        t21=o*1e12;
        t31=o*1e12;;
fclose(fp);

Another success try retrieves last value(I think)!!

C++

while ((i=fscanf(fp,"%f",&o))!=EOF)
	{
		size+=i;
		t21=o*1e12;
		t31=o*1e12;
	}
fclose(fp);

How to do that?please give solution!
Thanks in advance!

Step through the code with your debugger to see what is happening. It's impossible to guess from the above as we cannot see the input data.

C#

while ((i=fscanf(fp,"%f",&o))!=EOF)
    {
        size+=i;
        t21=o*1e12;
        t31=o*1e12;
    }
fclose(fp);

In above case declare an Integer variable after the expression of loop
just like this
while ((i=fscanf(fp,"%f",&o))!=EOF)

{ int n = 0;

t21=o*1e12;
t31=o*1e12;

n++;
}

/* Here By taking n value you can count how many float variables passed through the

loop according to that value you can calculate the memory used for that operation. */
