哎,初中没好好学,方程式y=x^2-5x+6要有实数解,必须b^2-4ac>=0,即(-5)^2-4(6-y)>=0,得出y>=-0.25估计你这y值肯定是大于0的,所以必然有两个不

楼主,运行了下你的程序貌似没什么问题,我的：publicvoidcol(){doubles=1;for(inti=2;i

publicclassSumOfEven{\x09publicstaticvoidmain(String[]args){\x09\x09intsum=0;\x09\x09for(inti=1;i

publicclassDemo{publicstaticvoidcalc(doublex){doubley=0;if(x0&&x

看的出来你是在考试呢.呵呵intsum=0;for(inti=1;i再问：嘻嘻……再答：娶我吧~啦啦啦珍竹意坊你的最佳答案在这呢啦啦啦再问：好的……呵呵我都不知道选哪个好

这不是数学么,总结出通项就行了.intn=5；//定义要循环的次数doublesum=0;for(inti=1;i

#includeusingnamespacestd;intmain(intargc,char*argv[]){ints=0;inttemp=1;inti;for(i=1;i

用for循环计算inta=2;ints=0;for(inti=1;i
