Q1 - Write a program which takes the values of length and breadth from user and check if it is
a square or not.

#include<iostream>
using namespace std;
int main(){
    int length;
    cout<<"Enter the length: ";
    cin>>length;
    int breadth;
    cout<<"Enter the breadth: ";
    cin>>breadth;
    
    if(length==breadth){
        cout<<"square :";
        
    }else{
        cout<<"It is a rectangular: ";
        
    }
    return 0;
}

Q2 - Write a program to print absolute value of a number entered by the user

#include<iostream>
using namespace std;
int main(){
    int num;
    cout<<"Enter a number: ";
    cin>>num;
    
    if(num<0){
        num=num*(-1);
        cout<<"Absolute number: "<<num<<endl;
    }
    return 0;
}

Q3- Write a program to take input from user for Cost Price (C.P.) and Selling Price(S.P.) and
calculate Profit or Loss.

#include<iostream>
using namespace std;
int main(){
    int cost_price;
    cout<<"Enter the cost price: ";
    cin>>cost_price;
    int selling_price;
    cout<<"Enter the selling price: ";
    cin>>selling_price;
    int profit = selling_price - cost_price;
    int loss = cost_price - selling_price;
    
    if(profit>0){
        cout<<"You are in the profit: "<<profit<<endl;
    }else{
        cout<<"You loose: "<<loss<<endl;
    }
    return 0;
}

Q4- Write a program to print positive number entered by the user, if user enters a negative
number, it is skipped.

#include<iostream>
using namespace std;
int main(){
    int num;
    cout<<"Enter a number: ";
    cin>>num;
    
    if(num>0){
        cout<<num<<endl;
    }else{
        cout<<"The number is nagetive skipped: "<<endl;
    }
    return 0;
}



Q5- Create a calculator using switch statement to perform addition, subtraction, multiplication
and division.




#include<iostream>
using namespace std;
int main(){
    char operators;
    cout<<"Enter the operators for calculate (+ - * /): ";
    cin>>operators;
  
        int num1;
         cout<<"Enter a num1 value: ";
         cin>>num1;
         int num2;
         cout<<"Enter a num2 value: ";
         cin>>num2;
 
  
    
    switch(operators){
        case '+':
                    cout<< num1 << " + " << num2 <<" = "<< num1 + num2 <<endl;
                    break;
        case '-':
                    cout<< num1 << " - " << num2 <<" = "<< num1 - num2 <<endl;
                    break;
        case '*':
                    cout<< num1 << " * " << num2 <<" = "<< num1 * num2 <<endl;
                    break;
        case '/':
                    cout<< num1 << " / " << num2 <<" = "<< num1 / num2 <<endl;
                    break;
        default:
                    cout<<"Enter the given operators: + - * / "<<endl;
    }

    return 0;
}
