Thread: excess elements in array initializer

Can anyone tell what warning the compiler is giving and how to overcome it?

Code:

 warning: excess elements in array initializer
{ {10, 20, 30, 40}, {50, 60, 70, 80}, {90, 100, 110, 120}},
^
note: (near initialization for 'array')

Code:

#include<stdio.h>          
int main ()
{  
   
   int arr[3][3][3]=   
        {
            { {11, 12, 13}, {14, 15, 16}, {17, 18, 19} },
            { {21, 22, 23}, {24, 25, 26}, {27, 28, 29}},
            { {31, 32, 33}, {34, 35, 36},{37, 38, 39} },
        };
        
   int array [2][3][4] = 


   {
       { {1, 2, 3}, { 4, 5, 6} },
       { {11, 12, 13}, {14, 15, 16}, {17, 18, 19}},
       { {10, 20, 30, 40}, {50, 60, 70, 80}, {90, 100, 110, 120}},
   };
   
  return 0;     
}

"excess elements in array initializer" sounds pretty straightforward: you're trying to initialise the array with too many elements. For example, in this case you declared the array as an int[2][3][4], but you're trying to initialise it as if it were an int[3][3][4].

so int array [2][3][4] -> 2*3*4 = 24 elements

Code:

   { {1, 2, 3}, { 4, 5, 6} },  // 6 elements        { {11, 12, 13}, {14, 15, 16}, {17, 18, 19}},// 9 elements 
       { {10, 20, 30, 40}, {50, 60, 70, 80}, {90, 100, 110, 120}}, //12 elemnets

I do not understand where the size is increasing

The array has only 2 rows. How many rows are you trying to fit in it? I counted 3:

Code:

   int array [2][3][4] = 



   {
       { {1, 2, 3}, { 4, 5, 6} },                                  // <== 1
       { {11, 12, 13}, {14, 15, 16}, {17, 18, 19}},                // <== 2
       { {10, 20, 30, 40}, {50, 60, 70, 80}, {90, 100, 110, 120}}, // <== 3 (too many!)
   };

The compiler is rightly telling you that you cannot do that.

.

I am confuse because there are so many way I do not understand how you counted row.

Code:

#include<stdio.h> int main() 
{ 


  int array [2][3][4] =  
 
{
    { {11, 12, 13, 14}, {15, 16, 17, 18}, {17, 18, 19, 20}},        
    { {10, 20, 30, 40}, {50, 60, 70, 80}, {90, 100, 110, 120}},
};


    return 0; 
}

C'mon, are you just trolling us now? I numbered the rows for you.

Your new code is correct, by the way.

sorry now I understood what I was doing wrong
