The purpose of passing parameters by reference in C programming is to allow a function to alter the value of a variable that exists outside the function. By passing a parameter by reference, the function can directly modify the original variable, rather than creating a new copy of it. This is useful when you want to update the value of a variable in a function and have that change reflected in the calling function.
