cout<< format("value is {}\n",a);} call by value => Internally, values are passed to and from a function, on a small data structure called a stack. The stack is relatively small space, requires processing power to manage. call by reference => passing large values to a function, re...
Learn how to create functions in C and how Call by Value or Call by reference works while calling functions in C.
The major difference between call by value and call by reference in C is that in call by value a copy of actual arguments/parameters is passed to respective formal arguments/parameters, while in call by reference the location (address) of actual argument

引用自https://zhidao.baidu.com/question/340173099.html Call by Value就是传值的方式,函数调用时是把实参的值传给形参,函数调用结束后形参的值不能带回给实参。Call by Reference就是传地址的方式,函数调用时是把实参的地值传给形参
