Suppose the address of memory location addressed by X is 002F0OFC What is the result of the output cout for the following statements? int X; int "XPtr XPtr++ Cout

Explanation / Answer

(10) int main() {

void *Pointer;

int Data = 25;

Pointer = &Data;

int *intPtr = static_cast<int*>(Pointer);

cout<<*intPtr;

}

(11) int main() {

void *Pointer;

double Data = 67.89;

Pointer = &Data;

double *doublePtr = static_cast<double*>(Pointer);

cout<<*doublePtr;

}

(12) int main() {

void *Pointer;

char Data = 'A';

Pointer = &Data;

char *charPtr = static_cast<char*>(Pointer);

cout<<*charPtr;

}

(13) int main() {

void *Pointer;

string Data = "Farzeen";

Pointer = &Data;

string *stringPtr = static_cast<string*>(Pointer);

cout<<*stringPtr;

}

As can be seen from the code we need to cast the void pointer into the respective counter.
