so I'm trying to read data from a text file into a vector but the data is like
13 24 12
45 23 12
so it goes as lines and i want to store them in the vector as lines. how will the program understands that it comes to the end of the line and stores each line as a pack? ıs there anything like multidimensional vectors ?? what should I do?
so i've been trying to learn about files and vectors and try to read data from file and transfer it into vector. data consists of 3 columns and 2500 rows of number. but the code below gives error saying one or more multiply defined symbols found which i couldn't understand. what is wrong??
