Question

a) if ( age >= 65 );
cout << "Age is greater than or equal to 65" << endl;
else
cout << "Age is less than 65 << endl";
b) if ( age >= 65 )
cout << "Age is greater than or equal to 65" << endl;
else;
cout << "Age is less than 65 << endl";
c) int x = 1, total;
while ( x <= 10 )
{
total += x;
++x;
}
d) While ( x <= 100 )
total += x;
++x;
e) while ( y > 0 )
{
cout << y << endl;
++y;
}

Answer 1

a) The semicolon at the end of the if condition should be removed. The closing double quote after the second endl should be placed after 65.
b) The semicolon after the else should be removed. The closing double quote after the second endl should be placed after 65.
c) Variable total should be initialized to 0.
d) The W in while should be lowercase. The while’s body should be enclosed in braces {}.
e) The variable y should be decremented (i.e., y--;), not incremented ( y++;).
