Initializing 2D Array : Two dimensional Array in C Programming

Initializing Array
Method 1 : Initializing all Elements

int a[3][2] = {
                 { 1 , 4 },
                 { 5 , 2 },
                 { 6 , 5 }
              };

• Declared array is of size 3 X 2 .
• Declared array contain total 6 elements.

Row 1 :  { 1 , 4 },
Row 2 :  { 5 , 2 },
Row 3 :  { 6 , 5 }

• Each Row is initialized Independently .
• Here -

a[0][0] = 1
a[0][1] = 4

Method 2 :

• Initialize all Array elements but this initialization is much straight forward .
• All values are assigned sequentially and row-wise

int a[3][2] = {1 , 4 , 5 , 2 , 6 , 5 };

Method 3 : Only Some Elements could be initialized

int a[3][2] = {
                 { 1 },
                 { 5 , 2 },
                 { 6 }
              };
