自己敲的代碼看不懂為什么j是那樣子。。。。
#include?<stdio.h>
int?main()
{
????int?i,?j,?k;
????for(i=1;?i<5;?i++)
????{
????????/*?觀察每行的空格數(shù)量，補(bǔ)全循環(huán)條件?*/
????????for(????j=i;j<5???;??j++??)??
????????{
????????????printf("?");????//輸出空格
????????}
????????/*?觀察每行*號(hào)的數(shù)量，補(bǔ)全循環(huán)條件?*/
????????for(?k=0?;??k<2*i-1?;??k++?????)?
????????{
????????????printf("*");???//每行輸出的*號(hào)
????????}
????????printf("\n");?????//每次循環(huán)換行
????}
????return?0;
}

當(dāng)i=1時(shí)，j=i=1，j<5,j++
然后反復(fù)循環(huán)4次
j一直增加到5的時(shí)候不滿足條件 不再執(zhí)行命令，所以第一行得出4個(gè)空格，
跳出這一層的for循環(huán)。
i=2,........循環(huán)3次 得到3個(gè)空格........

因?yàn)榭崭駭?shù)是4，3，2，1，所以j是這個(gè)樣子
