Why is my file output garbled?

When I read in a file and then output to a new file, the output is garbled, and I am trying to figure out why. I am trying to run the following code ``` #include<stdio.h> #include<stdlib.h> int main(int argc ,char *argv[]) { int c; FILE *of; FILE *f; of=fopen(argv[2],"w"); f=fopen(argv[1],"r"); while(c=getc(f)!=EOF) putc(c,of); fclose(of); fclose(f); return 0; } ``` But when I run it as follows `$./a.out temp new` where `temp` is an existing file whose contents are: `this is a temp file` and `new` doesn't exist before running the program But now when I cat the contents of `new` it is all messed up why it is so?
