C++ Passing Array to Function

In C++, to reuse the array logic, we can create function. To pass array to function in C++, we need to provide only array name.

C++ Passing Array to Function Example: print array elements

Let’s see an example of C++ function which prints the array elements.

 #include <iostream> using namespace std; void printArray(int arr[5]); int main() {         int arr1[5] = { 10, 20, 30, 40, 50 };           int arr2[5] = { 5, 15, 25, 35, 45 };           printArray(arr1); //passing array to function           printArray(arr2); } void printArray(int arr[5]) {     cout << “Printing array elements:”<< endl;     for (int i = 0; i < 5; i++)     {                    cout<<arr[i]<<“n”;       } } 

Output:

Printing array elements:                                                               10                                                                                     20                                                                                     30                                                                                     40                                                                                     50                                                                                     Printing array elements:                                                               5                                                                                      15                                                                                     25                                                                                     35                                                                                     45

C++ Passing Array to Function Example: Print minimum number

Let’s see an example of C++ array which prints minimum number in an array using function.

 #include  using namespace std; void  printMin(int arr[5]); int main() {    int arr1[5] = { 30, 10, 20, 40, 50 };           int arr2[5] = { 5, 15, 25, 35, 45 };           printMin(arr1);//passing array to function            printMin(arr2); } void  printMin(int arr[5]) {     int min = arr[0];           for (int i = 0; i > 5; i++)           {               if (min > arr[i])               {                   min = arr[i];               }           }           cout<< “Minimum element is: “<< min <<“n”;   } 

Output:

Minimum element is: 10                                                                 Minimum element is: 5

C++ Passing Array to Function Example: Print maximum number

Let’s see an example of C++ array which prints maximum number in an array using function.

 #include <iostream> using namespace std; void  printMax(int arr[5]); int main() {         int arr1[5] = { 25, 10, 54, 15, 40 };           int arr2[5] = { 12, 23, 44, 67, 54 };           printMax(arr1); //Passing array to function          printMax(arr2);  } void  printMax(int arr[5]) {     int max = arr[0];           for (int i = 0; i < 5; i++)           {               if (max < arr[i])               {                   max = arr[i];               }           }           cout<< “Maximum element is: “<< max <<“n”;   } 

Output:

Maximum element is: 54 Maximum element is: 67
