问题描述

 main()
{
 char *a = "a";
 *a = ''r'';
 printf(a);
}

1.输出是什么?

1. What is the output ?

main()
{
 int a;
 int *p;
 a = 5;
 p = &a
 printf(a,p,*p);
}

2.输出是什么?

3.流动结构之间的区别

2. What is the output ?

3. Difference between the flowing structure

struct pack
{
 unsigned int a:9;
} p;
struct pack
{
 unsigned int a;
} p;

struct data
{
 char name[80];
 double age;
}
 const data MyStruct = { "a", 1000 };
 strcpy (MyStruct.name, "p");
 printf(MyStruct.name);

4.输出?

4. Output ?

fib(n)
  if(n = 0)
     return 0
  if(n = 1)
     return 1
  
   return fib(n -1) + fib(n - 2)

5.模拟fin(5)

5. Simulate fin(5)

推荐答案

通常是内存冲突错误:"a"是静态字符串，不应允许您更改它.

Normally a memory violation error: "a" is a static string, and you should not be allowed to change it.

它不会编译，所以没有输出. printf不是内置函数，运算符或类型.

最可能的原因是缺少stdio.h.

那将是我在求职面试中的回答.

It won''t compile so there is no output. printf is not a built in function, operator nor type.

Most likely cause is a missing include of stdio.h.

That would be my response in a job interview.

输出为:r
没有错误！是的.

Output is: r
There is no error! yeah.
