[心得] 菱型
最近開始重新復習C，就想到以前上課做過的東西
年代久遠再寫一次，有其它什麼比較好的寫法嗎?
#include <stdio.h>
void printstar(int x){ //印出星形，因為半型空格的關係一次印二個
if(x==0)
return;
printf("**");
printstar(--x);
}
void printblank(int y){ //印出半型空白
if(y==0)
return;
printf(" ");
printblank(--y);
}
int main(){
int a,b,c;
scanf("%d",&a);
c = ((a/2)+1); //抓出菱型裡星星數量最多的row
for(b=1;b<=a;b++){ //輸入奇數給a，印出a個row的菱型
if(b>c){
printblank(b-c);
printstar((2*c)-b);
}else{
printblank(c-b);
printstar(b);
}
printf("\n");
}
getche();
}

我寫出來是這樣
#include <stdio.h>
int main(){
int a,b,c;
scanf("%d",&a);
b = a - 1;
c = a;
for(a;a>=1;){
if(b-->=1){
printf(" ");
}else{
for(int x=1;x<=c;x++)
printf("*");
printf("\n");
b = --a - 1;
}
}
getche();
}
