Program to check whether a given number is positive or negative.

Here, we have a basic program example to check if a number is positive or negative using different languages. This program is created in c language, c++, Java, and Python.

Program to check if a number is positive or negative in C language.

#include <stdio.h>
void main()
{
    int num;

    printf("Enter a number : ");
    scanf("%d", &num);
    if (num > 0)
        printf("The number is positive\n");
    else if (num == 0)
        printf("The number is zero\n");
    else
        printf("The number is negative\n");
}

Program to check if a number is positive or negative in C++ language.

#include<iostream>
using namespace std;
int main(){
int num;

    cout<<"Enter a number : ";
    cin>>num;
    if (num > 0)
       cout<<"The number is positive";
    else if (num == 0)
       cout<<"The number is zero";
    else
       cout<<"The number is negative";
}

Program to check if a number is positive or negative in Python language.

num = int(input("Enter a number:  "))
if num > 0 :
    print("The number is positive\n")
elif num == 0 :
    print("The number is zero\n")
else:
    print("The number is negative\n")

Program to check if a number is positive or negative in Java language.

import java.util.*;
class check
 {
   public static void main(String[] args)
    {
      int num;
  
      Scanner s=new Scanner(System.in);
      System.out.println("Enter a number :");
      num = s.nextInt();
     if(num > 0){
       System.out.println("The number is positive");
          }
     else if(num == 0){
       System.out.println("The number is zero");
          }
     else {
      System.out.println("The number is negative");      
          }
}
}
