  1. char a [] = “12345”;
    we haven’t defined the size of the array in declaration. This enables us to initialize values and the compiler will allocate necessary spaces.

    int i = strlen (a);
    The length of the array is determined by the number of character elements. strlen () returns the length of a string. here, i = 5

    printf (“here is 3 %d\n”,++i);
    the value of ‘i’ is pre-incremented. that is, the value of ‘i’ will be incremented before printing.

    and, “here is 3” is concatenated with the output to fuddle u.😛

    Correct Output : here is 3 6

  2. here is 36″Becouse 1 2 3 4 5 ” and ++i ,string start from 0 to array define so 1=0,2=1,3=2…….++i increment the value which occopy by null charactor .null charactor value here 5 and after increment 6 now we have 6 and printf defination has already 3 ,so combination is 36
