So iv just been getting into D programming, im liking it alot so 
far but i have come across one issue that i am unable to find a 
solution for.

Basically whenever i use readf(); to gather console input it wont 
run the program if there is code afterwards.

Here is an example:


import std.stdio;

int main(){
     long number, number2;
     write("Enter an integer: ");
     readf("%d", &number);
     return 0;
}


That works fine, but if i try and imput 2 numbers to seperate 
variables it doesn't work.


import std.stdio;

int main(){
     long number, number2;
     write("Enter an integer: ");
     readf("%d", &number);
     write("another no";
     readf("%d", &number2);
     return 0;
}



can anyone help me.

readf() does not automatically consume the end-of-line character.

 it doesn't work.


 import std.stdio;

 int main(){
 long number, number2;
 write("Enter an integer: ");
 readf("%d", &number);

A space character in the format string reads and ignores any number of 
whitespace at that position.

 write("another no";
 readf("%d", &number2);
 return 0;

Just insert spaces before the format specifiers:

import std.stdio;

int main(){
     long number, number2;
     write("Enter an integer: ");
     readf(" %d", &number);
     write("another no");
     readf(" %d", &number2);

     writeln(number, ' ', number2);
     return 0;
}
