Question

I have a text file filled with some numbers that I would like to read.

My text file looks like this.

1  2  3  5  0

2  5  8  5  0

7  8  6  9  0

I would like to read this text file into this structure:

struct numbers num[]

My struct is defined like this:

struct numbers {
       int totalnumbers;
};

The first time this would go into the structure:

1  2  3  5  0

And th second time:

2  5  8  5  0

And so on unitl the end of the file.

Thank very much in advance for any help.

My advice is to refer to your course notes/textbook and start writing code.
Honestly you will learn nothing by taking a completed program from the answers here.

• Start by writing a program to open the file and write the first line
  in the file to the console (hint fopen and fgets . . . I think, it’s been a while).
• Then put in a loop to write each line to the console.
• Then figure out how to split the line into individual numbers (hint
  strtok)
• Then figure out how to convert the numbers from the file (which are
  strings) to integers (hint prefer strtol over atoi)
• Then declare a large array and stick the numbers into it.

Programming is all about divide & conquer, which is really just solving the little problems one at a time until the big problems are solved.

Hope this helps.
