Program to Swap Elements Using Call by Reference #include <stdio.h> void cyclicSwap(int *a, int *b, int *c); int main() { int a, b, c; printf("Enter a, b and c respectively: "); scanf("%d %d %d", &a, &b, &c); printf("Value before swapping:\n"); printf("a = %d...
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
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...

There is no way for a C routine to call a Fortran routine and pass arguments by value. It is not possible to pass arrays, character strings, or structures by value. These are best passed by reference.Use the nonstandard Fortran function %VAL(arg) as an argument in the call....

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 significantly improve program ...
