Design a C function to print the elements of a given integers array.

Print Elements of an Integer Array: Function Design in c

Designing a function to print the elements of a given integer array means creating a function that takes an integer array and its size as parameters, and outputs the elements of the array to the console.

To design a function to print the elements of a given integers array in C, we can follow these steps:

Declare the function prototype. 

This specifies the function name, return type, and parameter types.

void print_array(int arr[], int size);

Implement the function body. 

This is where we write the code to print the elements of the array. One way to do this is to use a for loop to iterate over the array and print each element using the printf() function.

void print_array(int arr[], int size) {
  for (int i = 0; i < size; i++) {
    printf("%d ", arr[i]);
  }
  printf("\n");
}

Call the function from the main() function. 

To print the elements of an array, we can pass the array and its size as arguments to the print_array() function.

int main() {
  int arr[] = {1, 2, 3, 4, 5};
  int size = sizeof(arr) / sizeof(arr[0]);

  print_array(arr, size);

  return 0;
}

Output:

1 2 3 4 5

We can also design a more generic function to print the elements of an array of any data type. To do this, we can use a template.

template <typename T>
void print_array(T arr[], int size) {
  for (int i = 0; i < size; i++) {
    printf("%d ", arr[i]);
  }
  printf("\n");
}

To use this function, we can simply pass the array and its size as arguments, and the compiler will automatically infer the data type of the array elements.

For example, to print the elements of an array of floats, we can do the following:

float arr[] = {1.0f, 2.0f, 3.0f, 4.0f, 5.0f};
int size = sizeof(arr) / sizeof(arr[0]);

print_array(arr, size);

Output:

1.000000 2.000000 3.000000 4.000000 5.000000
