C++ Pass Array to a Function
To pass an array to a function in C++, you need to follow these steps:
- Define the function: Begin by defining the function that will receive the array as an argument. The function should have a return type and a parameter list that includes the array. For example:
void myFunction(int myArray[], int size) {
// Function code goes here
}
- Declare the array: In the calling function, declare and initialize the array that you want to pass to the function. For example:
int main() {
int myArray[5] = {1, 2, 3, 4, 5};
// Call the function here
return 0;
}
- Pass the array to the function: Call the function and pass the array as an argument. The name of the array is sufficient to pass it to the function. For example:
int main() {
int myArray[5] = {1, 2, 3, 4, 5};
myFunction(myArray, 5);
return 0;
}
- Access the array in the function: Inside the function, you can access the elements of the array using the parameter name. You can treat the parameter as a regular array and use it in any way you want. For example:
void myFunction(int myArray[], int size) {
for (int i = 0; i < size; i++) {
// Access the array elements here
int element = myArray[i];
// Do something with the element
}
}
That's it! You have successfully passed an array to a function in C++. Remember to adapt the code to your specific needs and modify the data types or array sizes as necessary.
