c - read() not working properly -

i trying read txt file using read() , print out output.

the text file has these numbers:

123 456  227 

and code shown below

#include<stdio.h> #include<stdlib.h> #include <fcntl.h> #include<io.h>  int main(int argc, char*argv[]){     char* input;     char* output;     int fd;     int temp = 0;     if(argc != 3){         printf("too many or few arguments\n");         exit(-1);     }     input = argv[1];     output = argv[2];      fd = open(input,o_rdonly,0);     if(fd == -1){         printf("read failed");         exit(-1);     }     while(read(fd, &temp ,sizeof(int)) != 0){         printf("%d\n", temp);     }     close(fd); } 

i tried running , output

221458993 909456394 842150410 842150455 

what doing wrong?

you need perform formatted i/o int value representation.

fscanf() or better, fgets() friend.
