C Programming- Control statements

What will be the output of the following C code? (Assuming that we have entered the value 1 in the standard input)

    #include <stdio.h>

    void main()

    {

        double ch;

        printf("enter a value between 1 to 2:");

        scanf("%lf", &ch);

        switch (ch)

        {

           case 1:

             printf("1");

             break;

           case 2:

             printf("2");

             break;

        }

    }
