Another situation in which call by reference is useful is when we need to return two or more values from a function, e. g., a function to return both area and perimeter of a circle. The call by reference mechanism is also very useful when passing large structures to a function and may...
While studying call by value and call by reference in C it is important to note that the story is different for arrays. When the name of an array is used as an argument, the value passed to the function is the location or address of the beginning of the array --there is no copying...

引用传递(Call by reference) 将参数传递给函数call by reference方法将参数的地址复制到形式参数中。 在函数内部,该地址用于访问调用中使用的实际参数。 这意味着对参数所做的更改会影响传递的参数。 要通过引用传递值,参数指针将像任何其他值一样传递给函数。 因此,您需要将函数参数声明为指针类型,如以下函数swap(...
abcabcabc}intcalculate(intx,int*y,int*z){*y=pow(x,2);*z=pow(x,3);return0;} Output When you run this code, it will produce the following output − a: 10 Square of a: 100 Cube of a: 1000 The Call by Reference mechanism is widely used when a function needs to perform memory...
2. Call by Reference in CIn call by reference we pass the address(reference) of a variable as argument to any function. When we pass the address of any variable as argument, then the function will have access to our variable, as it now knows where it is stored and hence can easily ...

引用调用 跟他相应的就是call by value 引用调用的话，会改变被调用的变量
The call by reference method of passing arguments to a function copies the reference of an argument into the formal parameter. Inside the function, the reference is used to access the actual argument used in the call. This means that changes made to the parameter affect the passed argument....
