Consider the following declaration of a ‘two-dimensional array in C:char a[100][100]; Assuming that the main memory is byte-addressable and that the array is stored starting from memory address 0, the address of a[40][50] is

• 4040

• 4050

• 5040

• 5050

If a doctor gives you 3 pills and tells you to take one pill every half hour, how long would it take before all the pills had been taken? How many hours?

Which is the quickest sorting technique out of the following?(Random dataset)

• Merge Sort

• Bubble Sort

• Insertion Sort

• Bucket Sort

Predict the output of below program:#include  int main(){    int arr[5];    // Assume base address of arr is 2000 and size of integer is 32 bit    printf("%u %u", arr + 1, &arr + 1);     return 0;}

• 2004 2020

• 2004 2004

• 2004 Garbage value

• The program fails to compile because Address-of operator cannot be used with array name

What is output?# include <stdio.h> void print(int arr[]){   int n = sizeof(arr)/sizeof(arr[0]);   int i;   for (i = 0; i < n; i++)      printf("%d ", arr[i]);} int main(){   int arr[] = {1, 2, 3, 4, 5, 6, 7, 8};   print(arr);   return 0;}

• 1,2,3,4,5,6,7,8

• Compilation Error

• 1

• Runtime Error

Output of following program?#include <stdio.h>int main(){    int i = 5;    printf("%d %d %d", i++, i++, i++);    return 0;}

• 7 6 5

• 5 6 7

• 7 7 7

• Compiler Dependent

Consider the following C functionvoid swap (int a, int b){   int temp;   temp = a;   a = b;   b = temp;}

• Call swap(x,y)

• Call swap(&x,&y)

• Swap(x,y) cannot be used as it does not return any value

• Swap(x,y) cannot be used as the parameters are passed by value
