Cpp Program to display smallest among three numbers

Cpp Program to display smallest among three numbers

In this tutorial, we will discuss the Cpp Program to display the smallest among the three numbers.

In this program, we will discuss a simple concept of the program to find the smallest number among three numbers in the Cpp programming language.

In this topic, we learn how to find the smallest number from given three numbers using if statements.

Find the smallest number using if statements

Among integer numbers

Program 1

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    int num1,num2,num3;  //declare the variables

    cout << "Enter the first number: ";
    cin>>num1;//get input from user for num1
    cout << "Enter the second number: ";
    cin>>num2;//get input from user for num2
    cout << "Enter the third number: ";
    cin>>num3;//get input from user for num3

    if(num1<=num2 && num1 <=num3){
        cout<<"\n Smallest number is: "<<num1;
    }//num1 compare with num2 and num3
    if(num2<=num1 && num2 <=num3){
        cout<<"\n Smallest number is: "<<num2;
    }//num2 compare with num1 and num3
    if(num3<=num1 && num3 <=num2){
        cout<<"\n Smallest number is: "<<num3;
    }//num3 compare with num1 and num2

    getch();
    return 0;
}

When the above code is compiled and executed, it produces the following results

Enter the first number: 54
Enter the second number: 23
Enter the third number: 32

Smallest number is: 23

Among float numbers

program 2

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    double num1,num2,num3;  //declare the variables

    cout << "Enter the first number: ";
    cin>>num1;//get input from user for num1
    cout << "Enter the second number: ";
    cin>>num2;//get input from user for num2
    cout << "Enter the third number: ";
    cin>>num3;//get input from user for num3

    if(num1<=num2 && num1 <=num3){
        cout<<"\n Smallest number is: "<<num1;
    }//num1 compare with num2 and num3
    if(num2<=num1 && num2 <=num3){
        cout<<"\n Smallest number is: "<<num2;
    }//num2 compare with num1 and num3
    if(num3<=num1 && num3 <=num2){
        cout<<"\n The smallest number is: "<<num3;
    }//num3 compare with num1 and num2

    getch();
    return 0;
}

When the above code is compiled and executed, it produces the following results

Enter the first number: 45.3
Enter the second number: 12.7
Enter the third number: 65.3

The smallest number is 12.7
