what you might try is creating a structure to hold the fields of each line - maybe Code: typedef struct { std::string cat; // xxx part int cnt; // numeric part std::string des; // segmentN part } mydata; you could create a vector for input and one for output Code: std::vector<std::vector<mydata> > in_data; std::vector<mydata> out_data; get a priming read on the file and store the first line; loop through your file and check each line against an occurance of cat field at the current_index position. if it doesn't exist, make room and update current_index. Code: if(in_data[current_index][0] != left_most_field_of_file_line) { in_data[current_index].push_back(std::vector<mydata>()); ++current_index; } in_data[current_index].push_back(tmp_mydata_variable); Once the file read completes, iterate over in_data and manipulate the fields as required storing it in out_data. That *should* allow you to write the formatted data to an output file or whatever you need to do. HTH
Create structure or class in C++ programming language. Use three data types as two strings and one integer. Start main() in C++ and then, call this created structure with its given name and arrange all variable and values as your require order of information.
