Array Computer Solutions: Two-Dimensional Array: Initialization of Two-Dimensional Array
Two-Dimensional Array
It has two subscript or index, first for row and second for column. For example:
int
The above has five rows and four columns. The total numbers of elements are 20. The subscripts of 20 elements are:
Initialization of Two-Dimensional Array
The initialization is done at the time of declaration of an array.
For example:
int A [2] [4] = {1, 2, 3, 4, 5,6, 7,8) .
For more clarity
int A [2] [4] = { {1,2, 3,4} , {5,6, 7,8} } .
The above data can be grouped. The inner braces are ignored by the compiler.
For two-dimensional array, two loops are required. The following program finds out the maximum value stored in two-dimensional array.
# include, iostream. h >
const int M = 5.
void main ()
{
int A [M] [M] , i, j, T.
cout ≫ “⧵n Enter Array Elements” .
for (i = 0; i < = M - 1; i ++)
for (j = 0; j < = M - 1; j ++)
cin ≫ A [i] [j] .
T = A [0] [0] .
for (i = 0; i < = M - 1; i ++)
for (j = 0; j < = M - 1; j ++)
{
If (T < A [i] [j]
T = A [i] [j] .
}
cout ≪ “Largest value” ≪ T ≪ “⧵n”
}
