Question

Rewrite the following program using functions, so that your main will look like below, and CAPACITY is declared as a global constant.

#include <iostream>

/** input numbers terminating with 'q'
* find the largest OR the smallest element, dependingf on the user's choice
* outputs the numbers with an arrow indicating the largest or the smallest
*/

using namespace std;

int main(){
const int CAPACITY = 1000;
double values[CAPACITY];
int current_size = 0;

cout << "Please enter values, Q to quit:" << endl;
double input;
while (cin >> input){
if (current_size < CAPACITY){
values[current_size] = input;
current_size++;
}
}
cin.clear();
cin.ignore();

cout << "Would you like to find (1) The Largest? or (2) The Smallest ";
cout << "Enter 1 or 2: ";
int choice;
cin >> choice;

double result = values[0];
for (int i = 1; i < current_size; i++){
if (choice == 1){ // if looking for largest
if (values[i] > result)
result = values[i];
}
else if (values[i] < result) // if looking for smallest
result = values[i];
}

cout << " The values are: ";

for (int i = 0; i < current_size; i++){
cout << values[i];
if (values[i] == result)
if (choice==1)
cout << " <== largest value";
else
cout << " <== smallest value";
cout << endl;
}
}

Explanation / Answer

#include <iostream>

using namespace std;

const int CAPACITY = 1000;

int current_size = 0;

void getvalues(double* values )

{

double input;

cout << "Please enter values, Q to quit:" << endl;

while (cin >> input)

{

if (current_size < CAPACITY)

{
values[current_size] = input;
current_size++;
}

}
}

double find_largest(double values[])

{

double result = values[0];

for(int i = 0 ; i < current_size; i++)

if(values[i] > result)

result = values[i];

return result;

}

double find_smallest(double values[])

{

double result = values[0];

for(int i = 0 ; i < current_size; i++)

if(values[i] < result)

result = values[i];

return result;

}

void printvalues(double values[])

{

cout << " The values are: ";

for (int i = 0; i < current_size; i++)
cout << values[i] << " ";

}

int main()

{

double values[CAPACITY];

getvalues(values);

printvalues(values);

cout << "Would you like to find (1) The Largest? or (2) The Smallest ";
cout << "Enter 1 or 2: ";

cin.clear();
   cin.ignore(255, ' ');
int choice;
cin >> choice;

switch(choice)

{

case 1:

cout << "The largest number in the array is " << find_largest(values) << endl;

break;

case 2:

cout << "The smallest number in the array is " << find_smallest(values) << endl;

break;

}

return 0;

}
