Q1) What is the output of the following program segments:
Program segment
output
int x=7, y=2,z=3;
cout<< "X = " << ++x << "\t Y= " << y++ << endl;
z+=y;
cout<< " now X = " << --x << "z= " << z << endl;
for(j = 4; j<=16; j*=2)
cout << j << endl;
x=1;
if(x<1)
x=x+5;
else if(x>1)
x=x-5;
else x=5;
cout<<”x=”<<x;
j = 4;
while ( j <= 16 )
{
j = 2 * j;
cout << j << endl;
}
for (k = 10; k <= 16; k++)
if (k%2!=0)
cout<<k<<endl;
Q2) suppose a, b and c are integer variables that have been assigned the values a = 8,
b = 3 and c =5. Determine the value of each of the following arithmetic
expressions.
a. Static _ cast <double> (a+c)
b.
c.
b/2 + 3 * ( a - c )
Static _ cast <int> (b)
Q3) Write a program in C++ that determines a student is succeed or not in a subject
