C Sample Question

  1. main()
    {
    int i;
    printf("%d",scanf("%d",&i));  // value 10 is given as input here
    }

    Answer:

    1

    Explanation:

    Scanf returns number of items successfully read and not 1/0. Here 10 is given as input which should have been scanned successfully. So number of items read is 1.
  2. #define f(g,g2) g##g2
    main()
    {
    int var12=100;
    printf("%d",f(var,12));
    	}

    Answer:

    100
  3. main()
    {
    int i=0;
     
    for(;i++;printf("%d",i)) ;
    printf("%d",i);
    }

    Answer:

    1

    Explanation:

    before entering into the for loop the checking condition is "evaluated". Here it evaluates to 0 (false) and comes out of the loop, and i is incremented (note the semicolon after the for loop).
  4. #include‹stdio.h›
    main()
    {
      char s[]={'a','b','c','\n','c','\0'};
      char *p,*str,*str1;
      p=&s[3];
      str=p;
      str1=s;
      printf("%d",++*p + ++*str1-32);
    }

    Answer:

    M

    Explanation:

    p is pointing to character '\n'.str1 is pointing to character 'a' ++*p meAnswer:"p is pointing to '\n' and that is incremented by one." the ASCII value of '\n' is 10. then it is incremented to 11. the value of ++*p is 11. ++*str1 meAnswer:"str1 is pointing to 'a' that is incremented by 1 and it becomes 'b'. ASCII value of 'b' is 98. both 11 and 98 is added and result is subtracted from 32". i.e. (11+98-32)=77("M");
  5. #include‹stdio.h›
    main()
    {
      struct xx
       {
          int x=3;
          char name[]="hello";
       };
    struct xx *s=malloc(sizeof(struct xx));
    printf("%d",s->x);
    printf("%s",s->name);
    }

    Answer:

    Compiler Error

    Explanation:

    Initialization should not be done for structure members inside the structure declaration
