Hello guys, is there a nice functional way to read the file
which is like
1,2,3,4,5,6
2,3,4,5,6,7
8,9,0,9,2,3
line by line, split numbers and remove each ','
convert it to int and save in a matrix int[][] arr?
Not tested, but I think the following should work:
auto matrix = str
.byLine
.map!((l) => l.split(",") // Split each line
.map!(to!int) // Turn into ints
.array) // Return an array
.array // Copy into an array
And how do tell here to read my file?
Replace str with File("myfile"):
auto matrix = File("myfile")
.byLine
.map!((l) => l.split(",") // Split each line
.map!(to!int) // Turn into ints
.array) // Return an array
.array // Copy into an array
import std.file, std.stdio, std.string, std.conv, std.algorithm,
std.array;
void main(){
auto matrix = File("test.txt")
.byLine
.map!((l) => l.split(",") // Split each line
.map!(to!int) // Turn into ints
.array) // Return an array
.array();
matrix.writeln;
}
compiles but crashes
