C编程中简单结构的问题 [英] Problem with simple struct in C programming

问题描述

我正在使用C编程问题。我在以全局方式声明结构时编译问题的程序（我需要这样做）。我得到以下编译错误：

Hi, I am having programming issues with C.The program that I am having compiling issues when declaring the structure in a global manner(I need it in this way).I am getting the following compiling errors:

g_str.c:13:9: error: expected declaration specifiers or ‘...’ before ‘men’
 sprintf(men[0].n[0],"hello1");
         ^~~
g_str.c:13:21: error: expected declaration specifiers or ‘...’ before string constant
 sprintf(men[0].n[0],"hello1");
                     ^~~~~~~~
g_str.c:14:9: error: expected declaration specifiers or ‘...’ before ‘men’
 sprintf(men[1].n[1],"hello2");
         ^~~
g_str.c:14:21: error: expected declaration specifiers or ‘...’ before string constant
 sprintf(men[1].n[1],"hello2");
                     ^~~~~~~~
g_str.c:15:9: error: expected declaration specifiers or ‘...’ before ‘men’
 sprintf(men[2].n[2],"hello3");
         ^~~
g_str.c:15:21: error: expected declaration specifiers or ‘...’ before string constant
 sprintf(men[2].n[2],"hello3");
                     ^~~~~~~~

我尝试过：

What I have tried:

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


struct str1 
  {
   char n[3][7];
  
};

struct str1 men[3]; 
 
sprintf(men[0].n[0],"hello1");
sprintf(men[1].n[1],"hello2");
sprintf(men[2].n[2],"hello3");

void main()		// the main function
{
printf(" %s",men[1].n[1]);

}

推荐答案

您的 sprintf（）电话不属于任何功能。你必须将它们移动到一个函数中（在这里使用 main（））：

Your sprintf() calls are outside of any function. You have to move them into a function (using main() here):

int main()
{
    sprintf(men[0].n[0],"hello1");
    sprintf(men[1].n[1],"hello2");
    sprintf(men[2].n[2],"hello3");
    printf(" %s",men[1].n[1]);
    return 0;
}
