C language fprintf, Fwrite, fscanf, fread mixed problems

int main (int argc, const char * argv[]) {

Insert code here ...

FILE * fp = fopen ("Test.txt", "w");

fprintf (FP, "%d%d", 3, 5);

int x = 4;

Fwrite (&x, sizeof (int), 1, FP);

int x = ' 1 ';

Fwrite (&x, sizeof (int), 1, FP);

Fclose (FP);

fp = fopen ("Test.txt", "R");

int des = 0;

int des2 = 0;

FSCANF (FP, "%d%d", &des, &des2);

printf ("Des:%d%d\n", DES, des2);

Fread (&des, sizeof (int), 1, FP);

printf ("Des:%d\n", des);

return 0;

}

FSCANF according to%d read, will skip the previous n white space characters (\ t, \ n, "), encountered non-numeric character termination, so later if it is fwrite, in the last number of fprintf with a space class to distinguish, let fscanf read the number terminated.

fprintf and fwrite can be mixed, one is formatted output, one is ASCII output by byte
