Passing array to function using call by reference When we pass the address of an array while calling a function then this is called function call by reference. When we pass an address as an argument, the function declaration should have apointeras a parameter to receive the passed address. #...
// in function modifyArray, "b" points to the original array "a" in memory void modifyArray( int b[], int sizeOfArray ) { // multiply each array element by 2 for ( int k = 0 ; k < sizeOfArray ; ++k ) b[ k ] *= 2; } // end function modifyArray // in function modif...
Effects of passing entire array by reference: The values of the original array are: 0 1 2 3 4 The values of the modified array are: 0 2 4 6 8 Effects of passing array element by value: The value of a[3] is 6 Value in modifyElement is 12 The value of a[ 3 ] is 67.7.Array...
Passing an Array by Reference To modify the original array inside a function, a pointer to the array should be used. Example packagemainimport"fmt"// Function to modify an arrayfuncmodifyArray(arr*[3]int){arr[0]=100// Modifying the first element}funcmain(){numbers:=[3]int{1,2,3}modi...
In the preceding example, we create an array and accept some integer value from the user at runtime. Then we passed array as argument toprintarray(int[] newarray)for printing and other calculation. It is same as other value passed as parameter to the function. ...

It's all the same to the compiler. There is a single pointer with a type of 'pointer to array'. You can always do sizeof(board) in the function to verify that all you have is a pointer. https://cdecl.org/ char (*board)[20] declare board as pointer to array 20 of char ...
The logical extension of the concept ofpassing a pointer to a functionleads to passing aUnionpointer, i.e., the pointer of amulti-dimensional array, passing the pointer of aself-referential structure, etc., all these have important uses in different application areas such as complex data struct...
In C, arrays are always accessed via pointers. If you try to pass an array by value, your code won't compile. While this is a good thing, keep in mind that you can update the underlying array, as we have seen with our batting roster. If you need to pass arrays to a function, ...
