不输入我的人名功能。我放置函数和所有内容的方式在逻辑上是正确的吗？

Question

我不知道为什么它不运行我的用户名功能。是我的编译器的错误还是我的编码的错误。如果我想放置指针，我应该把它放在哪里。并且，是否可以将指针 var 从主函数传递到其他函数？

#include <stdio.h>
#include <stdlib.h>

Answer 1

如果要使用函数 personname 打印姓名，第二个参数必须是 char * 或 char[ ] 而不是 char。

示例：

void personname(int a, char *b)
{
    printf ("\nPerson %d: %s",a+1, b);
}
