C :

#include<stdio.h>
int main()
{
  int i,j;
  for(i=0;i<5;i++){
    for(j=0;j<i;j++)
      printf(" ");
    printf("* * * * *\n");
  }
  return 0;
}

C++ :

#include <stdio.h>
int main() {
	char p[9] = {'*', ' ', '*', ' ', '*', ' ', '*', ' ', '*'};
	int i, j;
	for (i = 0;i < 5;i++) {
		for (j = 0;j < i;j++)
			printf("%c", ' ');
		for (j = 0;j < 9;j++)
			printf("%c", p[j]);
		puts("");
	}
	return 0;
}

Pascal :

begin
  writeln('* * * * *');
  writeln(' * * * * *');
  writeln('  * * * * *');
  writeln('   * * * * *');
  writeln('    * * * * *');
end.

Java :

public class Main {
   public static void main(String[] args) {
	  for (int i = 0; i < 5; i++) {
		for (int j = 1; j < i+1; j++) {
			System.out.print(" ") ;
		}
		for (int j = 0; j < 5; j++) {
			if(j!=4)
			System.out.print("*"+" ");
			else
				System.out.println("*");
		}
		
	}
   }
}

Python :

print "* * * * *"
print " * * * * *"
print "  * * * * *"
print "   * * * * *"
print "    * * * * *"
