I just started out with C programming. I've read a few basic tutorials.OK, so I nabbed some code from this very website which prints a file.I put this in a function called "void printfile()".I want two things from this thread. Firstly, I wanna know what this function does step-by-step. Secondly, how do I make it so that every time I call this function, I could pick which file it prints?Code:void printfile() { int c; FILE *file; file = fopen("text/README.txt", "r"); if (file) { while ((c = getc(file)) != EOF) putchar(c); fclose(file); } printf("\n");}
