Question

how to make a question in c languange multiple choice

Answer 1

You could do something like this:

#include <stdio.h>

int main()
{
    char choice;
    do
    {
        printf("What is your favourite food?\n");
        printf("\t1. Pizza?\n");
        printf("\t2. Burger\n");
        printf("\t3. Nachos\n");
        printf("? ");
        scanf(" %c", &choice);
    } while ('1' > choice || choice > '3');
    
    printf("Your picked: %c\n", choice);

    return 0;
}

The SPACE in the format string(" %c") before the "%c" means to read and ignore any white space character (e.g., newline from the last input).

This: while ('1' > choice || choice > '3');
Should be: while ('1' < choice || choice > '3');

No, it shouldn't.

`while ('1' > choice || choice > '3')`

means that choice is less than 1 or greater than 3, that is, it falls into the invalid ranges, so we keep repeating the question.

In your suggestion,  `while ('1' < choice || choice > '3');` means that choice is larger than 1 or larger than 3, which translates to choice is larger than 1. Basically, only 1 could be an acceptable answer, not 2 or 3.

But I appreciate people reading what I wrote and trying to fix it. ;)
