quiz game in c

[haidarrrr]

hi!
I'm trying to read lines from a text file line by line and store it in an array. the txt file has some question in it which will be asked to the player !

1: När kom potatisen till Europa?;A:1300-talet; B:1500-talet; C:900-talet;D:1700-talet\n
rätt svar : B

2: I vilken enhet mats elektrisk spänning ?;A:Ampere;B:Volt;C:Joule;D:Watt\n
Rätt svar: A

3: Från vilket land har vi fått lego?;A:Tyskland;B:Australien;C:Japan;D:Danmark\n
rätt svar : D

I want it to produce the following output:

1: När kom potatisen till Europa?
A:1300-talet
 B:1500-talet 
C:900-talet
D:1700-talet

When the user chooses it moves on to the next question ! it's a quiz i'm kinda of new to the language !



here is the code but i run into errors !! idk why!

struct quiz
{
	char questions[50];
	char* alt[4];
	char correctanswer[1];
};

int main(){

	struct quiz all_ques[10];
	int i = 0;

	FILE *haidar;
	haidar = fopen("gameee.txt", "r");
	char str[500];
	char *ptr;
	
	while (fgets(str, 500, haidar))               // read 500 characters
	{
		ptr = strtok(str, ";");           // split our findings around the " "
		strcpy(all_ques[i].questions, ptr);    // store the question

		ptr = strtok(NULL, ";");            // and keep splitting
		all_ques[i].alt[0] = malloc(10);
		strcpy(all_ques[i].alt[0], ptr);    // store the first option

		ptr = strtok(NULL, ";");       // and keep splitting
		all_ques[i].alt[1] = malloc(10);
		strcpy(all_ques[i].alt[1], ptr);    // store the second option

		ptr = strtok(NULL, ";");       // and keep splitting
		all_ques[i].alt[2] = malloc(10);
		strcpy(all_ques[i].alt[2], ptr);    // store the third option

		ptr = strtok(NULL, ";");       // and keep splitting
		all_ques[i].alt[3] = malloc(10);
		strcpy(all_ques[i].alt[3], ptr);    // store the fourth option

		fgets(str, 500, haidar);
		strcpy(all_ques[i].correctanswer, str);    // store the correct answer

		i++;

Try this:

int main()
{
	char str[] = "1: När kom potatisen till Europa ? ; A:1300 - talet; B:1500 - talet; C:900 - talet; D:1700 - talet\n"
	"rätt svar : B";

	int size = strlen(str);
	int i = 0;
	while (i < size)
	{
		if (str[i] != ';') 
		{
			cout << str[i];
		}
		else
		{
			cout << '\n';
		}
		++i;
			
	}

	cout << '\n';

}

The logic is to display character-by-character until you see a ;. Don't display the ; but display a \n instead.

If you reach the end of the string display a final \n.
