Question

In C++ please

Q4: There are 10 items in the shopping cart. 1. Assign a random price between 20-60 to each item. 2. Calculate the price maximum in the cart. If the price maximum is less than 55, re-run step 1. 3. If the class maximum is greater than 55, then print out price for every item to the screen.

Answer:

Q5: Write title lines for the functions that are called by the following main program. Do not supply the blocks for the functions. int main() { int a[5] = {3,1,4,1,5}; int x[2][3] = {{0,1,3},{2,4,8}}; string s= "Hello"; string t; cout << average(x, 2, 3) << endl; // prints the average: 3.0 t = doubleIt(s); cout << t << endl; // prints: HelloHello reverseCols(x, 2, 3); // prints: 3 0 1, 8 4 2 if (isPositive(a[0])) cout << "Positive" << endl; // prints: Positive cout << midEntry(a, 5) << endl; // prints: 4 return 0; }

(a) Title line for average

(b) Title line for doubleIt

(c) Title line for reverseCols

(d) Title line for isPositive

(e) Title line for midEntry

Answer 1

//c++ program

#include<iostream>
#include<stdlib.h>
#include<time.h>
using namespace std;

int maximum(int a[] , int n){
   int max = a[0];
  
   for(int i=1;i<n;i++){
       if(a[i] > max)max = a[i];
   }
   return max;
}

int main(){
   int itemPrice[10] , max;
   srand(time(NULL));
  
   while(1){
       for(int i=0;i<10;i++){
           itemPrice[i] = 20 + rand()%41;
       }
       max = maximum(itemPrice , 10);
      
       if(max > 55)break;
   }
  
   for(int i=0;i<10;i++){
       cout<<"item"<<(i+1)<<" price : "<<itemPrice[i]<<endl;
   }
   return 0;
}

(2)

(a) Title line for average
double average(int x[][3] , int row , int col);

(b) Title line for doubleIt
string doubleIt(string s);

(c) Title line for reverseCols
void reverseCols(int x[][3] , int row, int col);

(d) Title line for isPositive
bool isPositive(int n);

(e) Title line for midEntry
int midEntry(int a[] , int n);
