c - gcc compile error: unknown type name 'File' -

i learning how use file i/o using c.

this code in file, test.c

#include <stdio.h> #include <stdlib.h>  int main() {     file *fp;     char *mode = "r";     fp = fopen("testfile", mode);     if(fp == null) {         fprintf(stderr, "can't open input file testfile\n");         exit(1);     } } 

when compile code using : gcc -o test test.c

i error :

atria:~/471/a4> gcc -o test test.c test.c: in function ‘main’: test.c:6:5: error: unknown type name ‘file’      file *fp;      ^ test.c:10:8: warning: assignment incompatible pointer type [enabled default]      fp = fopen("testfile", mode);         ^ 

i thought maybe using wrong header file have included stdio.h

does have ideas why i'm getting error? thank in advance

that should file, not file.
