问题描述
我的代码可以正确使用一个单词，但是当我在开头添加if else语句并在另一个switch语句中添加时，出现了一些错误.任何帮助将不胜感激:)
这是代码:
I have my code working properly for one word but when I added in the if else statements at the start and another switch statement i am getting a few errors. Any help would be appreciated :)
here is the code:
#include<stdio.h>
#include<stdlib.h>
#define letters 6
#define letters2 9
main()
{
srand((unsigned)time(NULL));
int num = rand() %5 +1 ;
if(num == 1)
{
char word[letters] = {'f','l', 'i', 'c', 'k'};
char spaces[letters] = {'-', '-', '-', '-', '-'};
}
else
if(num == 2)
{
char word2[letters] = {'s','p', 'o', 'r', 't'};
char spaces[letters] = {'-', '-', '-', '-', '-'};
}
else
if(num == 3)
{
char word3[letters] = {'b','o', 'o', 't', 's'};
char spaces[letters] = {'-', '-', '-', '-', '-'};
}
else
if(num == 4)
{
char word4[letters2] = {'f','o', 'o', 't', 'b', 'a', 'l', 'l'};
char spaces2[letters2] = {'-', '-', '-', '-', '-', '-', '-', '-'};
}
else
if(num == 5 )
{
char word4[letters2] = {'s','w', 'i', 'm', 'm', 'i', 'n', 'g'};
char spaces2[letters2] = {'-', '-', '-', '-', '-', '-', '-', '-'};

推荐答案
在一些可执行代码之后有变量声明；在纯C语言中是不允许的.将声明移到功能块的开头.
You have variable declarations after some executable code; this is not allowed in pure C. Move the declarations to the beginning of the function block.
