is there a way to get a text file of the cmd prompt? that is, all the data that printf shows in codeblocks c?

Question

I'm currently writing a bunch of calculations in c using codeblocks and printing them off to the cmd prompt using the printf(); function. I am trying to create a graph from the data gathered. Is there a ways to get a hard copy or a text/doc file of all the data I printed out or better yet, is there a way to get all the values on the cmd prompt into a graph?

Why don't you just save them to a file?

Great example of writing to a file:

FILE *f = fopen("file.txt", "w");
if (f == NULL)
{
   printf("Error opening file!\n");
   exit(1);
}

 /* print some text */
 const char *text = "Write this to the file";
 fprintf(f, "Some text: %s\n", text);

/* print integers and floats */
int i = 1;
float py = 3.1415927;
fprintf(f, "Integer: %d, float: %f\n", i, py);

/* printing single chatacters */
char c = 'A';
fprintf(f, "A character: %c\n", c);

fclose(f);

Another solution is just pipeing the output using > file.txt
