C语言程序设计现代方法第二版，第10章课后编程习题
第一题
这题10.2中的pop函数没有用，在我的电脑里（vs2017）当把pop赋值给字符串时总是报错，尝试了各种办法都不行，提示是：char(*)()和char类型不兼容。求大神帮呀
#include
#include
#define STACK_SIZE 100
int top = 0;
char contents[STACK_SIZE];
void make_empty(void)
{
top = 0;
}
bool is_empty(void)
{
return top == 0;
}
bool is_full(void)
{
return top == STACK_SIZE;
}
void push(char i)

if (!is_full())
contents[top++] = i;
}
char pop(void)

if (!is_empty())
return contents[top--];

int n = 0;

while ((ch = getchar()) != '\n')
