AddAll - Adds all the doubles in the string with each other. Note every double is separated by a semi-colon. AddAll("1.245;2.9")=>4.145 double AddAll(const char* str) struct Sale char Person[100]; double sale; double tax; struct SaleStatistic double average Sale; double totalSale; double totalTax; (4) AddAl - Adds all the doubles in the string with semi-colon.

Answer 1

Answer: provided below

Explanation:

The code is provided below/

// the method to add all double value in the string

double AddAll(const char *str)

{

double total = 0;

vector<string> vec;

 

stringstream strStream(str);

 

while (strStream.good())

{

string substr;

getline(strStream, substr, ';');

vec.push_back(substr);

}

 

for (size_t i = 0; i < vec.size(); i++)

{

total = total + stod(vec[i]);

}

return total;

}

 

Program code with addition of the above for testing is provided thus

#include <iostream>

#include <sstream>

#include <vector>

using namespace std;

//addin all double value in syring

double AddAll(const char *str)

{

double total = 0;

vector<string> vec;

 

stringstream strStream(str);

 

while (strStream.good())

{

string substr;

getline(strStream, substr, ';');

vec.push_back(substr);

}

 

for (size_t i = 0; i < vec.size(); i++)

{

total = total + stod(vec[i]);

}

return total;

}

int main()

{

//method calling and display result

cout<<AddAll("1.245;2.9");

}

This gives output as:

4.145
