Program returns wrong value - c

Question

I have a problem in the following part of my code in C:
// reading pairs of parameters from input file
while((read = fscanf(input_file, "%d %d\n", &type, &col)) > 0 ) {
// checking reading errors
if (read != 2 || (type < 0 && type > 4) || (col > 9)) {
printf("Invalid input file format\n");
return 2;
}
// putting tetromino corresponding to given parameters to the field
if (put_tetromino(field, type, col) != 0) {
// if result is not 0, the tetromnio is out of range. Returning error
printf("Tetromino is out of field\n");
return 2;
}
}
The input file looks like this:
5 0
3 9
2 9
2 4
..
In the above part of the code I want to check if the input file has the correct format.
I should have 2 columns: the first (type) has to be a value between 0 and 4 and the second (col) has to be a value between 0 and 9. If the input file contains a wrong format, for example:
9 8
4 9
2 5
..
I want to return 2. But the program doesn't return 2, it returns 0 at the end of the main-function.

Answer 1

The expression (type < 0 && type > 4) is always false - a number can't be both larger than four and less than zero. You should use an || instead of an && there:
if (read != 2 || type < 0 || type > 4 || col > 9) {

Answer 2

actually a number can not be at a time bigger than 4 and smaller than 0 . and also you need to check if col < 0. it should look like this if (read != 2 || (type < 0 || type > 4) || (col<0 || col > 9))
for your need you need to this.
// reading pairs of parameters from input file
while((read = fscanf(input_file, "%d %d\n", &type, &col)) > 0 ) {
// checking reading errors
if (read != 2 || (type < 0 || type > 4) || (col<0 || col > 9)) {
printf("Invalid input file format\n");
return 2;
}
// putting tetromino corresponding to given parameters to the field
if (put_tetromino(field, type, col) != 0) {
// if result is not 0, the tetromnio is out of range. Returning error
printf("Tetromino is out of field\n");
return 2;
}
}
