cin>>number;
//User input the integer value and value is stored in variable number.
if(number<0)
//Value in variable number is checked by if condition. If the value of a number is less than 0, then the number is negative and control moves to the statement 9.But if the value of a number is greater than 0, then the number is positive and control moves to the statement 12.
{
//start of if body
cout<<"Number is negative"<<endl;
//Display the message that number is negative.
}
//ending of if
else
Control arrives at statement 12 if the condition is false at statement 8.
