Reading a text file in C -

i reading text file , trying display contents on console. here code:

#include "stdafx.h" #include <stdio.h> #include <string.h> #include <fstream>  int main() {     file* fp=null;     char buff[100];     fp=fopen("myfile.txt","r");     if(fp==null)     {         printf("couldn't open file!!!\n");     }     fseek(fp, 0, seek_end);     size_t file_size = ftell(fp);     fread(buff,file_size,1,fp);     printf("data read [%s]",buff);     fclose(fp);     return 0; } 

but redundant data being displayed on console; please point out mistake?

you need seek start of file before reading:

int main() {     file* fp=null;     char buff[100];     fp=fopen("myfile.txt","r");     if(fp==null)     {         printf("couldn't open file!!!\n");         exit(1);                     // <<< handle fopen failure     }     fseek(fp, 0, seek_end);     size_t file_size = ftell(fp);     fseek(fp, 0, seek_set);          // <<< seek start of file     fread(buff,file_size,1,fp);     printf("data read [%s]",buff);     fclose(fp);     return 0; }
