Hi all,



I have a data that looks like this:



1,2,3

1,3,4

2,4

1

2,4,5,6



I have these data in an excel file but can also copy into a txt file. I have declared a vector in c++ and want to read these data into my c++ code. For small problems, I typed it manually in my c++ code as:



int init1[] = {1,2,3};

std::vector<int> row1( init1, init1+sizeof(init1)/sizeof(init1[0]));

P.push_back(row1);



int init2[] = {1, 3, 4};

std::vector<int> row2( init2, init2+sizeof(init2)/sizeof(init2[0]));

P.push_back(row2);



and so on.



How can I import these data from txt or excel file?



Thanks
