1. Pass the addresses of the variables as parameters to the function. 2. In function definition receive the parameters through pointers. 3. Print the output and exit.Let’s take a look at pass by reference in C using two examples.
Inside the main() function, we declare a character array str and initialize it with the string Hello, world! We then use the printf() function to print a message with the value of the string. The message is enclosed in double quotes and contains a format specifier %s, indicating that a...
