1) What is the output of the following program?
Output:
8 1 6 5 5
Explanation : p is a pointer so sizeof returns
sizeof(char*), *p is of type char, sizeof("geeks") returns the number of characters including the null character, strlen(p) returns length of string pointed by p without null character and strlen returns number of characters without null character.
2) What is the output of the following program?
Output:
2 1 3
Explanation : The above initialization technique is unique but allowed in C.
3) What is the output of the following program?
Output:
1
Explanation : Even if this is function pointer, the sizeof will get the return type and returns the size of that data type. Here, the return type is char, so the output is 1.
4) What is the output of the following program?
Output:
4
Explanation: The '!' operator takes an argument and return 1 if the value is 0 and 0 otherwise. So, !2.3 is 0. To sizeof 0 is an integer and so the output is 4.
