what are actual and formal parameters in c language | formal and actual parameters

#cprogramming #functions #csciencetuts In the C programming language, function parameters are divided into two categories: actual parameters and formal parameters. Actual parameters are the values that are passed to a function when it is called. They are also known as the arguments of the function. Formal parameters are the variables that are declared in the function signature and used to receive the values of the actual parameters. In the example above, "a" and "b" are the formal parameters of the function "add". They are used to receive the values of the actual parameters (2 and 3) when the function is called. Formal parameters inside the function act as local variables, have their own scope and hold the data passed to them when the function is called. In C language call by value is default way of passing parameters, which means that, values of the actual parameters are copied to the corresponding formal parameters, the changes made to formal parameters do not reflect back to the actual parameters.
