C Miscellaneous — Part 2 MCQs with Explanations

p is pointing to character '\n'. str1 is pointing to character 'a'. ++*p: "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: "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").

In this problem we have an array of char pointers "s" pointing to start of 4 strings. Then we have ptr which is a pointer to a pointer of type char and a variable p which is a pointer to a pointer to a pointer of type char. p holds the initial value of ptr, i.e. p = s+3. The next statement increment value in p by 1 , thus now value of p = s+2. In the printf statement the expression is evaluated as follows: *++p causes gets value s+1 then the pre decrement is executed and we get s+1-1 = s which is pointing to the word "black". The indirection operator now gets the value from the array of s and adds 3 to the starting address. The string is printed starting from this position. Thus, the output is 'ck'.
