c语言数组的初始化

#include "stdio.h"

int main()
{
    int a[3][4];
    a[3][4]="1,2,3,4,5,6,7,8,9,10,11,12";
    int (*ptr)[4]=a,*p=a[0];
    printf("%d",*(ptr+2)+1);
    
    
    return 0;
}

例一：先来一个错误的例子

#include "stdio.h"
int main()
{  
   int  a[3][4];
   a[3][4]={1,2,3,4,5,6,7,8,9,10,11,12};
printf("%d",a[0][1]);  
    
    return 0;
}

编译不通过

 

例二：正确的版本

#include "stdio.h"
int main()
{

   int  a[3][4]={1,2,3,4,5,6,7,8,9,10,11,12};
printf("%d",a[0][1]);
    
    
    return 0;
}
