How to concatenate two integer arrays without using loop in C ?
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.
// arr1[] is of size m+n and arr2[] is of size n. This function // appends contents of arr2[] at the end of arr1[] void concatenate( int arr1[], int arr2[], int m, int n) { memcpy (arr1 + m, arr2, sizeof (arr2)); } |
