C Function Call by Reference - Learn how to use function call by reference in C programming, understand its syntax, advantages, and implementation with examples.
If data is passed by reference, a pointer to the data is copied instead of the actual variable as is done in a call by value. Because a pointer is copied, if the value at that pointers address is changed in the function, the value is also changed in main(). Let’s take a look a...
