Question

Ask user to enter three numbers (a,b,c). Write a program (c++) that will print the value to the following equations:

a. maximum value of one of these equations (functions separated by commas) (a, a+b, a-c) + maximum of (b, 2b-c, b+2a)

b. maximum value of (3, c+3a, 0) + minimum of (ab-2, 3c, ac)

Define functions max and min which will accept 3 numbers as arguments and return the mix and min of them correspondingly. Use these functions in order to calculate the vaules of the expressions.

Answer 1

Enter a value 10 b value: 20 nter c value: 30 Enter min<3. c+3a. >min(ab-2. 3c. ac> : 90 Press any key to continue - - -

=====================================================

#include<iostream>
using namespace std;

//Function prototype
int max(int a,int b,int c);
int min(int a,int b,int c);

int main()
{
   int a,b,c;
  
   //Read a,b,c values
   cout<<"Enter a value: ";
   cin>>a;
  
   cout<<"Enter b value: ";
   cin>>b;
  
   cout<<"Enter c value: ";
   cin>>c;
  
  
   //maximum value of one of these equations (functions separated by commas) (a, a+b, a-c) + maximum of (b, 2b-c, b+2a)
   cout<<"\n max(a, a+b, a-c) + max(b, 2b-c, b+2a) : "<<(max(a, a+b, a-c)+ max(b, 2*b-c, b+2*a))<<endl;
  
   //maximum value of (3, c+3a, 0) + minimum of (ab-2, 3c, ac)
   cout<<" min(3, c+3a, 0) + min(ab-2, 3c, ac) : "<<(min(3, c+3*a, 0)+ min(a*b-2, 3*c, a*c))<<endl;
  
   return 0;
}

//Method to calculate max value of a,b,c
int max(int a,int b,int c)
{
   int max;
   //Compare a>b
   if(a>b)
   {
       max = a;
   }
   else
   {
       max = b;
   }
  
   //Finally check with c
   if(c>max)
   {
       max = c;
   }
  
   return max;
}

//Method to calculate min of a,b,c
int min(int a,int b,int c)
{
   int min;
   //Compare a<b
   if(a<b)
   {
       min = a;
   }
   else
   {
       min = b;
   }
  
   //Finally check with c
   if(c<min)
   {
       min = c;
   }
  
   return min;
