All the friends who have learned programming know that, in order to learn various syntax structures in programming languages, we should try to solve various strange questions. Among them, "counting stars" seems to be one of them. What is "Counting Stars? Is to print various shapes of "*", positive triangle, inverted triangle, diamond and so on. This blog is purely designed to commemorate our past years.

 

A) Positive triangle

 

 

Void star_1 ()

{

Int outer;

Int inner;

 

For (outer = 1; outer <10; outer ++ ){

For (inner = 1; inner <= outer; inner ++ ){

Printf ("% c ",'*');

}

Printf ("\ n ");

}

}

Void star_1 ()

{

Int outer;

Int inner;

 

For (outer = 1; outer <10; outer ++ ){

For (inner = 1; inner <= outer; inner ++ ){

Printf ("% c ",'*');

}

Printf ("\ n ");

}

} B) inverted triangle

 

 

Void star_2 ()

{

Int outer;

Int inner;

For (outer = 9; outer> = 1; outer --){

For (inner = 1; inner <= outer; inner ++ ){

Printf ("% c ",'*');

}

Printf ("\ n ");

}

}

Void star_2 ()

{

Int outer;

Int inner;

For (outer = 9; outer> = 1; outer --){

For (inner = 1; inner <= outer; inner ++ ){

Printf ("% c ",'*');

}

Printf ("\ n ");

}

} C) in the Left triangle, there are two rows between two rows.

 

 

 

Void star_3 ()

{

Int outer;

Int inner;

For (outer =-4; outer <= 4; outer ++ ){

For (inner = 1; inner <= (5-abs (outer); inner ++ ){

Printf ("*");

}

 

For (; inner <= 5; inner ++ ){

Printf ("");

}

 

Printf ("\ n ");

}

}

Void star_3 ()

{

Int outer;

Int inner;

For (outer =-4; outer <= 4; outer ++ ){

For (inner = 1; inner <= (5-abs (outer); inner ++ ){

Printf ("*");

}

 

For (; inner <= 5; inner ++ ){

Printf ("");

}

 

Printf ("\ n ");

}

} D) Right Triangle

 

 

Void star_4 ()

{

Int outer;

Int inner;

For (outer =-4; outer <= 4; outer ++ ){

For (inner = 1; inner <= abs (outer); inner ++ ){

Printf ("");

}

For (; inner <= 5; inner ++ ){

Printf ("*");

}

Printf ("\ n ");

}

}

Void star_4 ()

{

Int outer;

Int inner;

For (outer =-4; outer <= 4; outer ++ ){

For (inner = 1; inner <= abs (outer); inner ++ ){

Printf ("");

}

For (; inner <= 5; inner ++ ){

Printf ("*");

}

Printf ("\ n ");

}

} E) Vertical Diamond

 

 

Void star_5 ()

{

Int outer;

Int inner;

For (outer =-4; outer <= 4; outer ++ ){

For (inner =-4; inner <= abs (outer)-5; inner ++ ){

Printf ("");

}

For (; inner <= 5-abs (outer); inner ++ ){

Printf ("*");

}

Printf ("\ n ");

}

}

Void star_5 ()

{

Int outer;

Int inner;

For (outer =-4; outer <= 4; outer ++ ){

For (inner =-4; inner <= abs (outer)-5; inner ++ ){

Printf ("");

}

For (; inner <= 5-abs (outer); inner ++ ){

Printf ("*");

}

Printf ("\ n ");

}

} F) Horizontal Diamond

 

 

Void star_6 ()

{

Int outer;

Int inner;

For (outer =-9; outer <= 0; outer ++ ){

For (inner = outer; inner <0; inner ++ ){

Printf ("");

}

For (; inner <= 9; inner ++ ){

Printf ("*");

}

Printf ("\ n ");

}

}

Void star_6 ()

{

Int outer;

Int inner;

For (outer =-9; outer <= 0; outer ++ ){

For (inner = outer; inner <0; inner ++ ){

Printf ("");

}

For (; inner <= 9; inner ++ ){

Printf ("*");

}

Printf ("\ n ");

}

}

 

G) Yang Hui triangle

 

 

Void star_7 ()

{

Int outer;

Int inner;

For (outer = 1; outer <10; outer ++ ){

For (inner = 1; inner <= outer; inner ++ ){

Printf ("% 3d", outer * inner );

}

Printf ("\ n ");

}

}

Void star_7 ()

{

Int outer;

Int inner;

For (outer = 1; outer <10; outer ++ ){

For (inner = 1; inner <= outer; inner ++ ){

Printf ("% 3d", outer * inner );

}

Printf ("\ n ");

}

}
