C :

#include<stdio.h>
void main()
{
	int a[3][4],i,j ;
	 	for(i=0;i<3;i++)
		 		for(j=0;j<4;j++)
			    scanf("%d",&a[i][j]);	 
	for(i=0;i<3;i++)
		for(j=0;j<4;j++)
		 {
			   printf("%4d",a[i][j]);
			  if(j==3)
				   printf("\n");
		 }
}

C++ :

#include <stdio.h>
int main() {
	int a[3][4];
	int * p;
	int i, j;
	for (i = 0;i < 12;i++)
		scanf("%d", a[0] + i);
	for (i = 0;i < 3;i++) {
		for (j = 0;j < 4;j++)
			printf("%4d", a[i][j]);
		printf("\n");
	}
	return 0;
}

Pascal :

var
  i,j:longint;
  a:array[1..3,1..4] of longint;
begin
  for i:=1 to 3 do
    for j:=1 to 4 do
      read(a[i,j]);
  for i:=1 to 3 do
    begin
      for j:=1 to 4 do write(a[i,j]:4);
      writeln;
    end;
end.

Java :

import java.util.*;

public class Main{
	public static void main (String[] args) {
		Scanner in=new Scanner(System.in);
		int c=0;
		int [][]a=new int[3][4];
		for(int i=0;i<3;i++)
			for(int j=0;j<4;j++)
				a[i][j]=in.nextInt();
		for(int i=0;i<3;i++){
			for(int j=0;j<4;j++){
				c++;
				if(c%4==0){
					System.out.println (String.format("%4d",a[i][j]));
				}
				else
					System.out.printf ("%4d",a[i][j]);
			}
		}
	}
