1、你测试下这个代码include ltunistdh include ltstdioh include ltstdlibh struct coordinate int xint y ball = 10，10int velocity = 1int height = 10int bottom = 0void drawint main；includeltstdiohint main int j，n char ch80，tran80 printfquot请输入电文quot getsch j=0 whilechj！=#39\0#39 ifchj==#39z#39 tranj=#39a#39；include int mainint m，n，p，q，s，rprintfquot请输入两个正整数m，n\nquotscanfquot%d，%dquot，m，nincludeltstdioh mainint a，b，t=0scanfquot%d %dquot，a，bif a；肯定要把p=0放在for循环之内啊，看 ifi%n==0p=p+n每次循环时，如果i%n==0，那么p的值就改变了为了使它对i后面的值没影响，所以每次都要置0。
