Question

Can anyone help me convert this to C++ but instead of using an array using a vector with 12 elements?

Creates a new NameSurferEntry from a data 1ine as it appears in the data file. Each line begins with the name, which is followed by integers giving the rank of that name for each *decade. o g public NameSurferEntry (String line) { String] splitResult - new String[12]; 1/ 12 elements including the name splitResult -line.split(" "); name splitResult[e]; for (int i-1; i

Explanation / Answer

Hi,

we can convert each line of this java to the respective c++ language. But there is one problem in c++ string library there is no default split function which will take a string and split it by the passed delimiter. So, we have to write our own split function here the code that is converted to c++ and split function is also included.

Things to observe before going to the program:

here in the existing Java code, the array ranks is not initialized. Because we are converting a string to the integer and appending it to the ranks array we can assume that the ranks array is initialized before the function call as a global variable and of type integer.

And in c++ there no need to specify a vector's length so in the code the split functions return value is directly stored and since we know that the file contains only 12 years data for loop i value we can directly use 12.

In c++ the Integer.parseInt() direct function is not there.

we have to define a string input stream and then we have to stream that value to an integer.

vector<string> splitStrings(string str, char dl)

{

string word = "";

int num = 0;

str = str + dl;

int l = str.size();

vector<string> substr_list;

for (int i = 0; i < l; i++) {

if (str[i] != dl)

word = word + str[i];

else {

if ((int)word.size() != 0)

substr_list.push_back(word);

word = "";

}

return substr_list;

}

int NameSurferEntry(String line){

char de=' ';

//calling the split function with delimiter ' '(space).

vector<string> splitResult=splitStrings(line,de);

name=splitResult[0];

for(int i=1;i<12;i++){

//defining string stream for the value we need to convert into the integer

stringstream converter(splitResult[i]);

//streaming the integer value to integer variable defined before

converter>>ranks[i-1];

}

return 0;

}
