Explanation / Answer

Part A

int *number;
printf( "%d ", *number ); //Without initializing the number pointer we are tyring to print the value it points to.

Part B

float *realPtr;
long *integerPtr;
integerPtr = realPtr; //we have to type cast when assigning one type of pointer to another type of pointer.
/* Here inegerPtr is of type long and realPtr is of type float.*/

Part C

int * x, y;
x = y; //we are assignig inter value to the integer type pointer.

Part D

char s[] = "this is a character array";
int count;
for ( ; *s != ''; ++s) //++s here we are incrementing the address of the array.We can't increment the address of the array
    printf( "%c ", *s );

Part E

float x = 19.34;
float xPtr = &x; /*Initializing the type float with float pointer.
xPtr is of float type and we can store only float values in xPtr,but here we are trying to store address the x which is of float type
*/
printf( "%f ", xPtr );

return 0;
