for statement

this for statement is supposed to return a number other than one, but will always return one, showing that it is not getting past the first try i believe. I changed this statement multiple times to about five lines of logic statements, this is its simplest form.

Code:

---

for(mchoice = 1; mchoice != choice && mchoice != car; mchoice++);

---

the rest of the code is as follows:

Code:

---

#include<stdio.h>

#include<stdlib.h>



int main(void){

    int car, choice, mchoice;

    car = rand() % 3 + 1;

    printf("Which door would you like to pick? (1-3) ");

    scanf("%i", &choice);

   

    for(mchoice = 1; mchoice != choice && mchoice != car; mchoice++);

   

    printf("Monty shows you a goat behind door number %i\n", mchoice);

   

    return 0;

}

Is there a reason you have a ; at the end of your for loop? I'm not even sure why you are using a loop here.

Code:

---

if( choice == car )
    ... you win a car
else
  ... you get a goat behind choice door

That loop is to generate a number other than the car and the persons choice, not respond with an answer. I am not sure how that if else logic would work for this. Can you elaborate?

Code:

---

for each number
    if number not car and number not choice
        you see a goat

    printf("Which door would you like to pick? (1-3) ");
 
    scanf("%i", &choice);
 
   
 
    for(mchoice = 1; mchoice == 3; mchoice++){
        if (mchoice != car && mchoice != choice) {
            printf("Monty shows you a goat behind door number %i\n", mchoice);
        }
    }
    return 0;

The code still does not work. What am i doing wrong?

mchoice is 1, so the truth test for your loop fails immediately, because you are testing to see if it's 3.
