Can you please tell me what's wrong with this code

void startHangmanGame(void) //second game function

{

int choice; //choice declaration

FILE *p; //pionter declaration

char data_list[20]; //string declaration

int input_status;

int counter = 0; //counter for the word

int counter2 = 5;//counter for attempts

char str[20]; //string declaration

char letter;

printf("Hangman Has Started ");

printf("choose a category: "); //print the menu

printf("1. Food. ");

printf("2. Objects. ");

printf("3. Names. ");

printf("4. Colors. ");

scanf("%d", &choice); //get the player choice

switch(choice) //switch for the choice

{

case 1:

p = fopen("food.txt", "r"); //open food file

break;

case 2:

p = fopen("objects.txt", "r"); //open objects file

break;

case 3:

p = fopen("names.txt", "r"); //open names file

break;

case 4:

p = fopen("colors.txt", "r"); //open colors file

break;

default:

printf("Invalid choice ");

} //end switch

srand(time(NULL)); //random function

int x=rand()%15;

printf("rand value=%d ",x);

if(p ==NULL) //check if the file is available

else

{

input_status=fscanf(p,"%s",data_list);

while(input_status==1)

{

input_status=fscanf(p,"%s",data_list);//start while loop

if(counter==x) //check if the counter = random value

{

strcpy(str, data_list); //copy string

printf("%s ", str);

//counter value update

}

counter++;

}//end while loop

fclose(p); //close the file

}

int size=strlen(str); //declare size

for(int i=0; i
