    Question Write a program to find the factors of any number entered.

    Code:
    #include<stdio.h>
    #include<math.h>
    main()
    {
        int num, i, rem;
        printf ("Enter the number to be factorised:");
        scanf ("\n%d",&num);
        printf ("The factors of %d =",num);
        for (i=0;i<=num;i++)
        {
            rem = num%i;
            if (rem==0)
            printf( "\t%d",i);
        }
    }

    I couldn't fix the error in this code. It's not working for me. Please help.

    scanf() should not have a \n in it.

    The variable i should start at 1, instead of 0 in the for loop

    Ya, I tried that too. even then the program is closing itself. It's not executing.

    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Programs are different with this, but for this particular program I had to use the "big gun" console pauser:

    Code:
    //has 2 lines
    while((n = getchar()) != '\n';
    n = getchar();
    scanf()'s always have this problem, so be aware of it. It's surely the most common question we're asked about on the forum.
