Write a program that reads in three integers and determines and prints the small

Question

Write a program that reads in three integers and determines and prints the smallest number numerically in the group. The values are NOT necessarily entered in numeric order. The program must prompt the user and read the three values from the console. It should then print the message "The smallest value among , , and is " (where , , , and are replaced by the actual values.). Use only techniques covered in Chapters 1, 2, 3, and 4. You may use the comparison operators "==", "!=", ">", ">=", "<", and "<=", and also the and ("&&") and or ("||") logical operators. You may also use "else" and nesting. The most direct solution to this assignment uses exactly 3 "if" statements, and no nesting or else statements. However, there are many ways to solve it.

Explanation / Answer

#include <iostream> //cout
using namespace std;

//function prototype
int Min3(int, int, int);

int main()
{
   //variable declaration
   int val1,val2,val3;
  
  
   //get input from console
   cout<<"First Int:";
   cin>>val1;
  
   cout<<" Second Int:";
   cin>>val2;
  
   cout<<" Third Int:";
   cin>>val3;
   cout<<endl;
  
   //Display result
   cout<<" The smallest value among "<<val1<<" , "<<val2<<" and "<<val3<<" is "<<Min3(val1,val2,val3)<<endl;
  
  
   return 0;
}

//Min3: return the smallest integers from 3 integers
int Min3(int v1, int v2, int v3)
{
   if (v1 <= v2 && v1 <= v3)
       return v1;
   if (v2 <= v1 && v2 <= v3)
       return v2;
   if (v3 <= v1 && v3 <= v2)
       return v3;
}
