学过编程的朋友都知道,当初为了学习编程语言中的各种语法结构,我们要试着解决各种各样奇怪的题目。其中“数星星”就似乎其中的一种。什么是“数星星”呢?就是打印各种形状的“*”,正三角、倒三角、菱形等等。本篇博客纯粹为了纪念我们逝去的岁月。
a)正三角
void star_1() { int outer; int inner; for(outer = 1; outer <10; outer ++){ for(inner = 1; inner <= outer; inner ++){ printf("%c ", ‘*‘); } printf("\n"); } }b)倒三角
void star_2() { int outer; int inner; for(outer = 9; outer >= 1; outer --){ for(inner = 1; inner <= outer; inner ++){ printf("%c ", ‘*‘); } printf("\n"); } }c)左三角
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) 右三角
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)垂直菱形
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)水平菱形
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)杨辉三角形
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"); } }
