Ok so i am writing a C program. The program is simple enough, when i run the program i give it a few parameter Ex ./proj1 cat hat bat, so then it asks me to input a list of words the program gives counts of how many times "cat", "hat", and "bat" occurs in that list. I have the program working great.
Example
./pro1 cat hat bat
cat
.
(the program recognized a "." as the end of input)
Result:
cat:1
hat:0
bat:0
ok so my program runs perfectly in every test case i can think of, but I have to pass a series of tests that my professor has mas made. here is the code of that test.
char *args[] = {"./main", "cat", "hat","bat",NULL};
char *result[] = {"Looking for 3 words\n",
"Result:\n",
"cat:1\n",
"hat:0\n",
"bat:0\n"};
FILE *out;
FILE *test;
test=fopen("test","w");
int i;
char *buffer=malloc(100*sizeof(char));
out = fopen("smp0.in", "w");
fprintf(out, "cat\n");
fprintf(out, ".\n");
fclose(out);
freopen("smp0.in", "r", stdin);
freopen("smp0.out", "w", stdout);
quit_if(main(4, args) != EXIT_SUCCESS);
fclose(stdin);
fclose(stdout);
out = fopen("smp0.out", "r");
for (i = 0; i < 5; i++) {
quit_if(fgets(buffer, 100, out) == NULL);
quit_if(strcmp(buffer, result[i]));
}
fclose(out);
return EXIT_SUCCESS;
}
ok so sending the quit_if() is the method that makes it fail. specifically
quit_if(strcmp(buffer, result[i]));
My output when i run the program is exactly as described. But between freopen() diverting stdout to a file and then reading it back it has changed somehow.
Result:
cat:1
hat:0
batÿ:0
is what the output becomes, but it is not like that before the file write and read, and for some reason it is always that weird y character.
any advice would be greatly appreciated. Sorry for not posting more code but it's because it is a school project. I am confident that it is the test that is wrong in some way and not my code, fixing the test is part of the project as well.
