Question 1

Time: 00:00:00
Suppose that in a C program snippet, followings statements are used.
i) sizeof(int);

ii) sizeof(int*);

iii) sizeof(int**);

Only i) would compile successfully and it would return size as 4

Only i) would compile successfully and it would return size as 4

i), ii) and iii) would compile successfully and size of each would be same i.e. 4

i), ii) and iii) would compile successfully and size of each would be same i.e. 4

i), ii) and iii) would compile successfully but the size of each would be different and would be decided at run time.

i), ii) and iii) would compile successfully but the size of each would be different and would be decided at run time.

ii) and iii) would result in compile error but i) would compile and result in size as 4.

ii) and iii) would result in compile error but i) would compile and result in size as 4.

Question 2

Time: 00:00:00
Assume int is 4 bytes, char is 1 byte and float is 4 bytes. Also, assume that pointer size is 4 bytes (i.e. typical case)








char *pChar;

int *pInt;

float *pFloat;


sizeof(pChar);

sizeof(pInt);

sizeof(pFloat);

Question 3

Time: 00:00:00
#include "stdlib.h"

int main()

{

 int *pInt;

 int **ppInt1;

 int **ppInt2;


 pInt = (int*)malloc(sizeof(int));

 ppInt1 = (int**)malloc(10*sizeof(int*));

 ppInt2 = (int**)malloc(10*sizeof(int*));


 free(pInt);

 free(ppInt1);

 free(*ppInt2);

 return 0;

}

malloc() for ppInt1 and ppInt2 isn’t correct. It’ll give compile time error.

malloc() for ppInt1 and ppInt2 isn’t correct. It’ll give compile time error.

free(*ppInt2) is not correct. It’ll give compile time error

free(*ppInt2) is not correct. It’ll give compile time error

free(*ppInt2) is not correct. It’ll give run time error.

free(*ppInt2) is not correct. It’ll give run time error.

No issue with any of the malloc() and free() i.e. no compile/run time error.

No issue with any of the malloc() and free() i.e. no compile/run time error.
