Ah -'0' worked, I was trying it without the single quotes.

arr[n] = (double)line2[j]-'0';
Is -'0' preferable to -48? will it always give me the correct answer?

I was debating just doing a...

Yes although I believe I tried the -'0' method and it did not work. I had to subtract 48: hence the


(double)line2[j]-48

So I take the string C001:1001:1 and I want to get teh 1001 part. and then I want to get each of the characters of 1001. So "1","0","0","1". and I will be putting these into a double array. ...

Thanks for all the replies/help. So it appears I am allocating the correct way? but when I run something unexpected(line2[1][100000]) I am jsut getting a random event idiosyncracy?
So basically...

So I am revisting some of my old code and I was creating 2D array dynamically in 2 different ways:


double **allocate_array(int row_dim, int col_dim){
double **result;
int i;
...

No I want to take the second term(1001) of that line(: are delimiters), and then pull out each character of that term("1","0","0","1") each into its own variable.

So I want to cast a single...

I tried both ways:


printf("char :i=%d,j=%d and value=%c\n",i,j,line2[j-1]);
printf("float :i=%d,j=%d and value=%f\n",i,j,line2[j-1]);
...

Hi I have the following code:


i = 1;
while (fscanf(infile, "%[^:]:%[^:]:%s\n", line1,line2,line3) != EOF) {
printf("Line was composed of %s, %s, %s\n",line1,line2,line3);
