Changing a text file to an array
Hello, I was wondering it it's possible to change my textfile to an arrray.
For example this is my text file: 4x3 + 5x^2 + 3x + 2
I want to get the number of coefficients and the coefficients. That would look something like this
Is this possible? I have a hard time figuring out a code for thisCode:double [number of coef]= {2,3,5,4}
To read from a file, you will need these.
- fopen
- fgets
Then you might end up with a char buffer like this
Next, write some code which identifies all the +/-, which gives you each of the terms of the polynomial.Code:char buff[100] = "4x^3 + 5x^2 + 3x + 2";
Then you separate each term into a coefficient and a power (4 and 3, 5 and 2, 3 and 1, 2 and 0)
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
Is this similar to stream? I'm a beginner and I'm really having a hard time implementing this.
Changing
IntoCode:char buff[100] = "4x^3 + 5x^2 + 3x + 2";
is trivial.Code:char buff[100]; fgets(buff,sizeof(buff),fp);
Focus on trying to split buff into it's components.
As a first exercise, try to get it to print the following
Found term=+4x^3
Found term=+5x^2
Found term=+3x^1
Found term=+2x^0
You can omit the red parts initially, but you should be able to infer them.

As we all do on occasion I think you've got your forums crossed.Originally Posted by Salem
