Pass Array To Function C++. Syntax for Passing Arrays as Function Parameters The syntax for passing an array to a function is returnType functionName(dataType arrayName[arraySize]) { // code } Let's see an example int total(int marks[5]) { // code } Here we have passed an int type array named marks to the function total() The size of the array is 5.
We can use array names as parameters during function declaration To pass arrays to a function we specify the array type followed by the name of the array and square brackets in the function parameters The square brackets tell the compiler that the first function parameter is an array otherwise a variable will be assumed Passing onedimensional arrays to functions The general syntax for passing an array to a function in C++ is FunctionName (ArrayName).
How Arrays are Passed to Functions in C/C++? GeeksforGeeks
C++ does not allow to pass an entire array as an argument to a function However You can pass a pointer to an array by specifying the array's name without an index There are three ways to pass a 2D array to a function − Specify the size of columns of 2D array void processArr(int a[][10]) { // Do something } Pass array containing pointers.
C++ Passing Arrays to Functions
Ways to pass an array to a function in C/C++ are Formal parameters as pointers Formal parameters as sized arrays Formal parameters as unsized arrays Call By Value can be invoked using a wrapper of structure where an array is wrapped inside a structure It is possible to return an array from a function by changing return type of function to pointer of data type of the array That’s all for now folks! Thanks for reading.

A whole array cannot be passed as an argument to a function in C++ You can however pass a pointer to an array without an index by specifying the array’s name In C when we pass an array to a function say fun () it is always treated as a pointer by fun () The below example demonstrates the same.

You can't directly pass an array to a function you can only pass a pointer As a result the language “helpfully” converts a prototype such as this void foo (char arr[]) into this void foo (char *arr) And when you call the function you don't pass it a complete array you pass a pointer to the first element.
