C language problem plz help me?

Question

Given an int variable datum that has already been declared, write a statement that reads an integer value from standard input into this variable.

Answer 1

Sounds like a java Programing  Question????

Look into java.io.BufferedReader, java.lang.Integer.parseInt and java.util.Scanner

BufferedReader in = new BufferedReader(new InputStreamReader(System.in));

datum = in.readLine();

and

BufferedReader in = new BufferedReader(new InputStreamReader(System.in));

datum = Integer.parseInt(in.readLine());

Answer 2

void main(void)

{

  int a;

printf("input-->");

  scanf("%d",&a);

}

Answer 3

First off your in the wrong forum and while programming is c is not my forte let me try a stab at it anyway.

var = Cinput;

Answer 4

???

Answer 5

As you're not asking for a complete function, but only a statement that reads an integer value from standard input, here's your answer (Just one line):

scanf ("%d", &datum);

Note:

As it was specified, the variable datum was previously declared ( int datum; ) and possibly initialized ( datum = 0; ).
