When we pass the values to the function, The compiler is actually making a clone or copy of the original value and then passing that clone values to the function instead of In C Programming Language, there are two methods to pass parameters from calling function to called function and they are as follows Call by Value; Call by Reference; Call by Value. In call by value parameter passing method, the copy of actual parameter values are copied to formal parameters and these formal parameters are used in called While studying call by value and call by reference in C it is important to note that the story is different for arrays. When the name of an array is used as an argument, the value passed to the function is the location or address of the beginning of the array --there is no copying of array elements. Call by Value & Call By Reference In C: C Tutorial In Hindi #31 To run a C program, we need an IDE’s like Visual Studio Code or Codeblocks.

In this method, Values of the declared variables passed as the parameters to the function. When we pass the values to the function, The compiler is actually making a clone or copy of the original value and then passing that clone values to the function instead of In C Programming Language, there are two methods to pass parameters from calling function to called function and they are as follows Call by Value; Call by Reference; Call by Value.
