不确定如何解决＆＃34;无效的初始化程序＆＃34;编译时出错

Question

#include <stdio.h>
#include <string.h>

int main(void)
{
  char alpha[26] = '0', nl;

  while (alpha != '0'){
        scanf("%c", &alpha);
        scanf("%c", &nl);
        printf("the character is %c\n", alpha);
 }

}

我尝试编译时遇到无效的初始化程序错误。错误在char alpha[26] = '0', nl;行内。 谢谢你的帮助！
