Variable number can have any value. cout<<"Enter any number"<<endl; //Display message. 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. { cout<<"Number is positive"<<endl; //Display message that number is positive. } //Ending of else. } //Ending of main function. |
