Thread: How to merge two array

Here is a solution that does not use pointers and gets to the heart of the issue, element positions are not the same in the second loop

Code:

/*Merge2Arraystoa3rd.c*/

#include<stdio.h>

int main ()
{
    int i;

    int x[] = { 1, 9, 3, 4 };
    int y[] = { 7, 2, 5, 8, 6 };
//    int z[9];
    int z[10]; // a C string must have one extra element for the "\0" //See Strings in C - GeeksforGeeks
    for (i = 0; i <4; i++)
    {
        //&z[i];
        z[i] = x[i]; // each element in array x will copy into the same array element position in z
    }                // but this is not the same in the next iteration

    for (i = 0; i <5; i++) // Element position 0 in y is equal to element position 4 in z
    {
        //&z[i];
        z[i+4] = y[i];
    }

    for (i = 0; i <9; i++)
    {
       printf("z[%d] = %d\n", i, z[i]);
    }
    return 0;
