  3. What should be on the second mid term exam? • Can you name the topics and provide some type of organization for these topics? Winter Quarter

  4. Topics for Midterm 2 • Repetition structures • for for (k=1,a=0; k<20; k=k+3) a++; • while k=1; a=0; while(k<20) {k+=3; a++;} • do { } while k=1; a=0; do {k+=3; a++;} while(k<20); • Selection structures • if • if else • if else if else Winter Quarter

  5. Topics for Midterm 2 File I/O • FILE statement • detecting an EOF • functions – fopen, fclose, fscanf, fprintf, fgets • feof example: FILE *fptr; int k,a; float b,c; fptr=fopen(“data.dat”,”r”); k=fscanf(fptr,”%f”,&b); if(feof(fptr)||k==EOF) printf(“End of File\n”); Winter Quarter

  6. Topics for Midterm 2 • I/O • formats, including the specifications for the various data types -- %d, %f, %c, %ld, %s • functions – scanf, printf, getchar, putchar examples: int k,a; float b,c; k = scanf (“%f%d%f”, &b, &a, &c) ; if (k==EOF) printf (“End of file\n”) ; else if (k<3) printf (“Conversion Error\n”) ; Winter Quarter
