Error while reading input from console in D language

I am writing a simple code to input the number of candies and balloons to be brought to a party. I have written 

import std.stdio;
void main()
{
 int candiesCount;
 readf("%s", &candiesCount);

write("How many balloons are there? ");
int balloonCount;
readf("%s", &balloonCount);

writeln("Got it: There are ", candiesCount, " candies",
        " and ", balloonCount, " balloons.");
}

but after entering the number of candies I get this error :

Unexpected '

Pls Help me as I am new to this language.

Solution

  • This stumped me for awhile as well. Andrei explains that readf is very picky about the input matching the format string.

    You just need to add \n to the end your format strings. I think this is because you press enter to submit the input, but I'm not entirely sure (I am still new to this language as well).

    It should look something like this:

    readf("%s\n", &candiesCount);
...
readf("%s\n", &balloonCount);
