Given two arrays such that first array has enough extra space to accommodate elements of second array. How to concatenate second array to first in C without using any loop in program?
Example:
Input: arr1[5] = {1, 2, 3}
arr2[] = {4, 5}
Output: arr1[] = {1, 2, 3, 4, 5}
We strongly recommend you to minimize your browser and try this yourself first.
Hint: We may use library functions in C.
The idea is to use memcpy() or memmove() in C.
void concatenate( int arr1[], int arr2[], int m, int n)
{
memcpy (arr1 + m, arr2, sizeof (arr2));
}

Thanks to Utkarsh Trivedi for suggesting above solution.
