Write a C program to check if a given Number is zero or Positive or Negative Using if...else statement.

Use of if else statement in c 

Here we have if else statement it is a conditional operator. We have to write the condition of if statement in brackets "( )" like this if(condition), it implies that if the condition is true Only then the body of if statement will be executed. Otherwise, program control skip the body of the if statement
When multiple if else statement is being used then we use else if  instead of multiple if statement.



The code is

#include <stdio.h>
int main()
{
double number;
scanf("%lf", &number);
if(number==0)
printf("The number is 0.\n");
else if(number>0)
printf("Positive number.\n");
else
printf("Negative number.\n"); 

            }

Input                                                                      Output 0 The number is 0. -0.9 Negative number.
