1. What happens when you attempt to compile and run
the following code?
#include <iostream>

using namespace std;

int main() {

char t[3][3], *p = (char *)t;

for(int i = 0; i < 9; i++)

*p++ = ‘a’ + i;

cout << t[1][1];

return 0;
}

 It prints g
 It prints c
 Compilation fails
 It prints e
2. What happens when you attempt to compile and run the
following code?
#include <iostream>
using namespace std;

int main() {
float *ft[3] = { new float[3], new float[3], new float[3] }, *p;

for(int i = 0; i < 3; i++) {
p = ft[i];
*p = p[1] = *(p + 2) = 10 * i;
}
cout << ft[1][1];
delete [] ft[0];
delete [] ft[1];
delete [] ft[2];
return 0;
}

 It prints 20
 It prints 30
 It prints 10
 Compilation fails

, 3. What happens when you attempt to compile and run the
following code?
#include <iostream>
using namespace std;

int main() {
int *it[3];

for(int i = 0; i < 3; i++) {
it[i] = new int [i + 1];
for(int j = 0; j < i + 1; j++)
it[i][j] = 10 * i + j;
}
cout << it[2][2];
for(int i = 0; i < 3; i++)
delete [] it[i];
return 0;
}

 It prints 33
 It prints 22
 It prints 11
 Compilation fails
4. What happens when you attempt to compile and run the
following code?
#include <iostream>
using namespace std;

int main() {
short s = 1;
int i = 2;
long l = 3;
float f = 4.4;
double d = 6.6;

cout << s/i + f/i + d/s;
return 0;
}

 It prints 4.4
 Compilation fails
 It prints 6.6
 It prints 8.8
