Question

3.21 LAB: Smallest number

Answer 1

Answer:

#include <iostream>

using namespace std;

int main(){

   int a, b, c;

   cout<<"Enter three integers: ";

   cin>>a>>b>>c;

   if(a<=b && a<=c){

       cout<<"Smallest: "<<a;    }

   else if(b<=a && b<=c){

       cout<<"Smallest: "<<b;    }

   else{

       cout<<"Smallest: "<<c;    }

   return 0;

}

Explanation:

This line declares three integer variables a, b and c    

int a, b, c;

This line prompts the user for three integer inputs

   cout<<"Enter three integers: ";

This line gets the inputs

   cin>>a>>b>>c;

This checks if the first is the smallest

   if(a<=b && a<=c){

If yes, it prints the first as the smallest

       cout<<"Smallest: "<<a;    }

This checks if the second is the smallest

   else if(b<=a && b<=c){

If yes, it prints the second as the smallest

       cout<<"Smallest: "<<b;    }

If the above conditions are not true, then the third number is printed as the smallest

   else{

       cout<<"Smallest: "<<c;

   }
