Question 1

In C programming, when you have an array `int a[] = {10, 20, 30, 40};` and a pointer `int *p = a;`, what is the difference in the output of `sizeof(a)` and `sizeof(p)` assuming a 4-byte integer and an 8-byte pointer?

Question 2

When an array like `int a[5] = {1, 2, 3, 4, 5};` is passed to a function `void fun(int a[])`, what will `sizeof(a)` print inside the `fun` function, assuming a 4-byte integer?

Question 3

Consider the C code: `int a[] = {5, 10, 15, 20}; int i = 0; a[i++] += 5; a[++i] += 10;`. What will be the values in array `a` after these operations?

Question 4

In the C code `int a[] = {2, 4, 6, 8, 10, 12}; for (i = 0; i < 6; i += 2) { a[i+1] = a[i] + a[i+1]; }`, which elements of the array `a` will be modified and how?

Question 5

Consider the C code `int a[5] = {1, 2, 3, 4, 5}; for (i = 0; i < 5; i++) { *(a + i) = *(a + i) * (i + 1); }`. What does `*(a + i)` represent?

Question 6

Given a 2D array `int a[2][3] = {{1, 2, 3}, {4, 5, 6}};`, and the nested loops `for (i = 0; i < 2; i++) { for (j = 2; j >= 0; j--) { printf("%d ", a[i][j]); } }`, what will be the output?

Question 7

In C, if `int a[2][2] = {{10, 20}, {30, 40}};` and `int (*p)[2] = a;`, what does `p[0][0]` print?

Accepted Answer

2

Question 8

Consider the C function `void update(int b[], int n)` which modifies an array. If `int a[] = {1, 2, 3, 4, 5};` is passed to this function, what will be the final state of array `a` after the function call?

Accepted Answer

0

Question 9

Given `int a[] = {2, 4, 6, 8};` and `int n = sizeof(a) / sizeof(a[0]);`, what will be the output of the loop `for (i = 0; i < n; i++) { a[i] = a[i] + n; }` followed by printing the array?

Accepted Answer

Question 10

Consider the C code `int a[3][2] = {{1, 2}, {3, 4}, {5, 6}}; int *p = &a[0][0];`. If the loop `for (i = 0; i < 6; i++) { if (i % 2 == 0) printf("%d ", *(p + i)); }` is executed, what will be printed?
