Can we pass an array as argument to a function?
Therefore, it isn't possible to pass an array "by value". An array in a function call will be passed to the function as a pointer, which is analogous to passing the array by reference.
People also ask, can an array be used as an argument to a function?
If we pass an entire array to a function, all the elements of the array can be accessed within the function. Single array elements can also be passed as arguments. This can be done in exactly the same way as we pass variables to a function.
Also Know, can we pass array as argument in Java? You can pass arrays to a method just like normal variables. When we pass an array to a method as an argument, actually the address of the array in the memory is passed (reference). Therefore, any changes to this array in the method will affect the array.
In respect to this, can we pass an array as argument to a function in C?
Note: In C programming, you can pass arrays to functions, however, you cannot return arrays from functions.
How do you pass an array to a function?
C language passing an array to function example
- #include<stdio.h>
- int minarray(int arr[],int size){
- int min=arr[0];
- int i=0;
- for(i=1;i<size;i++){
- if(min>arr[i]){
- min=arr[i];
- }
