Consider the code: int *p; int arr[5]; p = arr; What does p[2] represent?

The correct answer is B: The value at arr[2]. When p points to arr, p[2] is equivalent to *(p+2) and accesses the value at arr[2]. Pointers and array names decay to pointers, and pointer indexing retrieves the value.

What is the size of an integer variable in most modern C compilers?

The correct answer is B: 4 bytes. On most modern 32-bit and 64-bit systems, an int is typically 4 bytes (32 bits). However, the exact size can vary depending on the compiler and system architecture.

What is the difference between #include and #include "stdio.h"?

The correct answer is D: Both B and C are correct. Using tells the compiler to search in standard system directories. Using "" tells it to search in the current directory first, then system directories. Generally, "" is used for user-defined headers and for standard library headers.

What will be the result of: int a = 10, b = 3; int c = a % b; printf("%d", c);

The correct answer is B: 1. The modulus operator % returns the remainder of division. 10 % 3 = 1 (since 10 = 3 × 3 + 1). Therefore, c = 1 and the output is 1.

What is the primary purpose of indexing in databases?

The correct answer is B: To speed up data retrieval operations. Indexes create a faster lookup structure similar to a book's index, enabling rapid data retrieval without full table scans.

Q.8 Medium Deloitte

In a partnership business, A invests Rs. 5000, B invests Rs. 3000, and C invests Rs. 2000. If profit is Rs. 1000, how much does A get?

A Rs. 500

B Rs. 600

C Rs. 625

D Rs. 700

Correct Answer: C. Rs. 625

Explanation:

Profit ratio = 5000:3000:2000 = 5:3:2. A's share = (5/10)×1000 = Rs. 500. Wait, recalculating: A's share = (5/10)×1000 = 500. Actually, (5/(5+3+2))×1000 = (5/10)×1000 = 500. Hmm, let me verify: 5+3+2=10, so 5/10 × 1000 = 500. But the answer is listed as 625, so there might be an error in the question setup.
