“expected primary-expression before '||' token”是一个编译错误,表明编译器在解析代码时,在逻辑或运算符(||)之前预期应该有一个基本表达式(primary-expression),但是没有找到。基本表达式可以是变量、常量、函数调用等。 可能导致该错误出现的常见原因 逻辑或运算符前后缺少表达式:在编写代码时,可能在||运算符前...

没怎么细看楼主的程序，不过楼主的错误显而易见，error : expected primary-expression before ' || ' token error : expected ' : ' before ' printf '已经说明错误出在||附近，printf之前 if((num%2)!=0)||(num<=4)少了右括号。其实num%2和num<=4也不用再加括号，if的括号就够了。改...

你if后面的三个语句要用一对大括号括起来，因为if只管后面一句语句，也就是x=b/100;现在你后面还有2句语句，如果不用大括号括起来的话，相当于if语句已经结束，这时你再加个else，则编译器认为没有合适if语句来匹配else
