(programming C++) Specifically, I am not allowed to include string, cstdlib or math libraries. Also, I am not allowed to use any built-in functions of c-strings.

char* zigzagMerge(const char *s1, const char* s2)

{

/* create and return a new c-string by merging (putting in one) s1 and s2 in zigzag form.

Example, zigzagMerge of "abc" and "defgh" will be "adbecfgh"

*/

}

//Test zigzagMerge function

cout << endl;

char *s3 = zigzagMerge(s1, s2);

cout << "The zigzag merge of " << s1 << " and " << s2 << " is " << s3 << endl;

Here is the ideal output:

The zigzag merge of massachussettes and abmaachu is maabsmsaaacchhuussettes
