C语言!帮忙看下我写的这个程序错在哪里了,谢谢!用的是二次插值法.
float f1=f(a1);\/\/float p;\/\/这里有重复定义的错，p已经是函数的参数了，while(1){ a2=a1+p;f2=f(a2);if(f2>=f1){ if(fabs(f2-f1)<acc)p=p\/2;else p=-p;} else break;} while(1)

这个程序是谁写的啊,一点都不规范,而且还不完整,把main函数里的switch语句后加个(c)就可以正常编译运行了。程序的作用是选择要转换为阴历还是阳历,例如选择阴历好后输入一组年月日(格式例1981.11.30,在1980到2015年之间),之后程序将为你转换为阴历(1981.11.5)帮你注释了两个函数,另外两个函数的思想相同,总的来...
