Files - reading & writing

FILE *fp;

fp = fopen(“somefile”,”r”);

char c; char *p; /* storage */

char *s; int n; /* n char */

• fscanf(fp,”%f”,&fidentifier);

fprintf(fp,”%f”,fidentifier);

• c = getc(fp); /* ? getchar() for terminal I/O */

putc(c,fp);

• fgets(s,n,fp); /* read n characters i.e. string */

fputs(s,fp);

• fread(p,s,n,fp) & f write(p,s,n,p) are used to read & write chunks of binary data (p 480 of text)
