The eval_expr function had to be prototyped as follows : int eval_expr(char const *str); Given mandatory main : The program expects that there is no syntax errors in the expression. Usage : ./eval_expr EXPRESSION Example Grade The program crashed when a minus sign was put between two pa...

3.一些内置命令:expr、shift、eval、trap等 4.Shell内置命令总结 1.函数的使用 和其它编程语言一样,Bash也可以定义函数 一个函数就是一个子程序,用于完成特定的任务,当有重复代码,或者一个任务只需要很少的修改就被重复几次执行时,这时你应该考虑使用函数 ...
constexprautof(inti){returni+1;}constevalautog(inti){returni+1;}autox(inti){returnf(1)+f(i)+g(1)+g(i);// error: call to consteval function 'g(i)' is not a constant expression} g(1)可以,g(i)不行,前者可以编译器求值,后者不行。与constexpr函数的区别很明显了。
