大佬写个小程序，第九题，c语言的，万分感谢

代码如下，如有帮助，请采纳，谢谢。

#include <stdio.h>
#include <string>
int main()
{
	
	char* a = "abcdefg";
	char* b = "efghijklmn";

	int lena = strlen(a);
	int lenb = strlen(b);
	char* p = new char[lena+lenb + 1];
	
	memset(p,0,lena + lenb + 1);
	int i = 0;
	int ai = 0;
	int bi = 0;
	while(ai < lena || bi < lenb)
	{
		if (ai < lena && bi < lenb)
		{
			if (a[ai] < b[bi])
			{
				p[i] = a[ai];
				ai++;
				i++;
			}else
			{
				p[i] = b[bi];
				bi++;
				i++;
			}
		}else if (ai >= lena && bi < lenb)
		{
			p[i] = b[bi];
			bi++;
			i++;
		}else if (ai <lena && bi >= lenb)
		{
			p[i] = a[ai];
			ai++;
			i++;
		}else
			break;

	}

	printf(">>%s",p);

	delete[] p;
	p = 0;

	getchar();
	getchar();
	return 0;
}
