if (name.charAt(i) == ' ')
startWord = true;
else
startWord = false;
}
2. What is the output?
class complex
{
double re;
double im;
public:
complex (): re (0), im (0) {}
complex (double n) {re=n, im=n ;}
complex (int m, int n) {re=m, im=n ;}
void print () {cout<};
void main ()
{
complex c3;
double i=5;
c3 = i;
c3.print ();
}
3. What is the output in the following program?
void main ()
{
char c=-64;
int i=-32
unsigned int u =-16;
if(c>i)
{
printf("pass1,");
if(cprintf("pass2");
else
printf("Fail2");
}
else{
printf("Fail1);
if(iprintf("pass2");
else
printf("Fail2");
}
}
4. What will be the result of the following program?

void main( )
{
char *g="string";
strcpy(gxxx(),g);
g = gxxx();
strcpy(g,"old string");
printf("The string is : %s",gxxx());
}
5. What is the output?
#include
class fig2d
{
int dim1;
int dim2;
public:
fig2d () {dim1=5; dim2=6 ;}
virtual void operator<< (ostream & rhs);
};
void fig2d::operator<<(ostream &rhs)
{
rhs <dim1<<" "<dim2<<" ";
}
void main ()
{
fig2d obj1;
obj1 << cout;
}
