49 : C Program to Check enterned number is positive or negative

Check out the complete list of c-programs : C Program List    



This is a very simple C program to check if the inputted number is a positive or negative number.



If entered Number is less then zero then it is a negative number.

If the entered number is greater then zero then it is a positive number.

If the number is equal to zero then it is neither positive nor negative.

This can be achieved using if-else statements,

Logic : 

if(number > 0) {
     
     //It is a Positive number
        
    }
    else if(number < 0) {
         
     //It is a Negative number    
        
    }
    
    else {
    
      //number == 0
      //Number is neither positive nor negative      
  
   }


Variables :

number : Datatype int : Holds value of year inputted by the user. %d is the Format specifier for int's
