Array:-
Array:- Array is a collection of homogeneous data type element.When ever we want to represent a collection of same data type elements with a single name then we go for array concept.
Each element of array is represented with one index index value.
1st element index value will be[0]
2nd element index value will be[1]
3rd element index value will be[2]
Last element index value will be(Size-1) or (n-1).
Declare an Array in C:-
data_type variable_name [sire_of_array];
Initializing array while declaration
int age[5] = {1, 13, 8, 16, 12}; or
int age[] = {1, 13, 8, 16, 12};
Initializing array after declaration
int weight[6];
weight[0]=10;
weight[1]=11;
weight[2]=13;
weight[3]=14;
weight[4]=16;
weight[5]=17;
Example:-
#include <stdio.h>
int main()
{
int weight [6] = {1,2,3,4,5,6};
/* To print all the elements of the array
for (int i=0; i < 6; i++){
printf("%d", height[i]);
}
return 0;
}
=> C programming language supports multidimensional arrays.
Declare of Two dimensional Array in C:
int a[3][4] = {
{0, 1, 2, 3} ,
{4, 5, 6, 7} ,
{8, 9, 10, 11}
};
Note:- a[3][4]
a[3] resepents rows and a[4] columns.
Example:-
#include <stdio.h>
int main () {
/* an array with 6 rows and 2 columns*/
int a[6][2] = { {0,0}, {1,2}, {2,4}, {3,6},{4,8} {5,9}};
int i, j;
for ( i = 0; i < 6; i++ ) {
for ( j = 0; j < 2; j++ ) {
printf("a[%d][%d] = %d\n", i,j, a[i][j] );
}
}
return 0;
}
