    } 

4. What will be the output of the following C code?

    {
        short i;
        for (i = 1; i >= 0; i++)
            printf("%d\n", i);
 
    } 

5. What will be the output of the following C code?

    #include <stdio.h>
    void main()

        printf("%d", a);
    } 

6. What will be the output of the following C code?

    #include <stdio.h>
    int main()
    {
        int x = 97;
        switch (x)
        {
           case 'a':
              printf("yes ");
              break;
           case 97:
              printf("no\n");
              break;
        }
    }

    } 

8. 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()
    {
        int ch;
        printf("enter a value between 1 to 2:");
        scanf("%d", &ch);
        switch (ch, ch + 1)
        {
           case 1:
              printf("1\n");
              break;
           case 2:
              printf("2");
              break;
        }
    }
