assigning variables within if statement and used outside

m0bb1n (34)
Hello,

How can I assign a variable within a if statement and allow it to be used outside of it? If that is not possible, what the best way to make the question order random.

Any feedback is appreciated, Thanks!

    srand(time(0));

    for(int i=0; i<2; i++) {
        string question;
        string a;
        string b;
        string c;
        string d;
        string correct;
        int points;

        int random=rand()%(3+1)+1;

        if(random==1) {
            question = "How many continents are there?";
            a= "5";
            b= "7";
            c="3";

            points=50;
        }

        if(random==2) {
            question = "What is the distance from the sun to the earth? (IN MILLION MILES)";
            a= "150";
            b= "32";
            c= "92";

            correct= "92";
            points= 100;
        }

        if(random==3) {
            question = "What is the width of San Francisco? (IN KM!)";
            a= "13";
            b= "16";
            c= "12";
            d= "19";
            correct= "19";
            points= 200;
        }
    printQuestion(question, a, b, c, d);
    askQuestion (question,  a, b, c, d,  correct,  points, totalPoints, correctAnswers);
 }

Not possible.

Aren't you already doing that? Depending on the random number, you get a question?

I would use else if though.

if(random == 1)
else if(random == 2)
else if(random == 3)

I am such a fool. I had assigned the int random to numbers that didn't have if statement.

Thanks anyway!
