Random function

Is it possible in C to use the random function to generate different questions to ask the user, from the different questions functions Iā€™ve made? (Iā€™m trying to do this for the quiz game Iā€™m developing, so when they choose all it will display random questions Iā€™ve already written in the other functions)šŸ˜…

I don't know that much about c, but there is a function int rand(), which will choose a random intreger between 0 and 32767. With this information, you could write something like this (it's not an actual c program) /*create arrays with the questions and the answers at the same index*/ array questions = ['q1','q2']; array answers = ['a1','a2']; /*the function*/ int random_question(){ /*random intreger between 0 and (in this case) 3 - 1, so that if rand() chooses 30270, it would output 20, ask me if you don't get it*/ int index = int rand() % (amount of questions - 1); /*print the question*/ printf(questions[index]); /*empty variable, not sure if this is possible, otherewise do string ans = "";*/ string ans; /*ask for the user input*/ fgets("%s",&ans); /*I actually had to search this one*/ /*then check if the user has it correct, otherwise show the ans*/ if(ans === answers[index]){ printf("Amazing, that's correct"); } else { printf("Sorry, the answer is: "+answers[index]); } }

No problem, you're welcome. I found a lot of the stuff on internet, so maybe that might be a tip for the next time
