How to use the 'fread' function in C language?

#include  #include  #include  int main() { FILE *stream; char msg[]="this is a test"; char buf[20]; if ((stream=fopen("dummy.fil","w+"))==NULL) { fprintf(stderr,"cannot open output file.\n"); return 1; } /*write some data to the file*/ fwrite(msg,1,strlen(msg)+1,stream); /*seek to the beginning of the file*/ fseek(stream,0,SEEK_SET); /*read the data and display it*/ fread(buf,1,strlen(msg)+1,stream); printf("%s\n",buf); fclose(stream); system("pause"); return 0; }

int main(void) { FILE *stream; char list[30]; int i,numread,numwritten; /*open file in text mode:*/ if ((stream=fopen("fread.out","w+t"))!=NULL) { for (i=0;i<25;i++) { list[i]=(char)('z'-i); } /*write 25 characters to stram*/ numwritten=fwrite(list,sizeof(char),25,stream); printf("Wrote %d items\n",numwritten); fclose(stream); } else printf("Problem opening the file\n"); if ((stream=fopen("fread.out","r+t"))!=NULL) { numread=fread(list,sizeof(char),25,stream); printf("Number of items read =%d\n",numread); printf("Contents of buffer=%.25s\n",list); fclose(stream); } else { printf("File could not be opened\n"); } system("pause"); return 0; }
