Different ways to initialize the array in C | initialize the array in C | Ways to initialize the array in C Language





We can initialize the array either at the time of declaration of after the declaration
For example: Initialization of an array at time of declaration:
int arr1[5] ={1,2,3,4,5};
Note: Size of an array is optional when we are initializing it at the time of declaration.
For example:
int arr2[]={1,2,3,4};
In this case size of array is number of elements i.e. 4
Initialization of an array after the declaration
int arr3[5]; //declaration of array
Initialization of array
arr[0]=1;
arr[1]=2;
arr[2]=3;
arr[3]=4;
arr[4]=5;
Initialization of multidimensional array at the time of declaration
int arr4[3][2]= {{1,2},{3,4},{5,6}};
Note: size of first dimension is optional when we are initializing it at the time of declaration.
For example:
int arr5[][3]={{1,2,3},{1},{2,3}};
Size of first dimension will adjust according to number of elements. In this case it is three.
Default value of rest element is zero in case of integer array.
We can also initialize multidimensional array at the time of declaration with using inner {}.
For example:
int arr6[][2][3]={1,2,3,4};
In this case default value of rest elements are zero.
Declaration of multidimensional array:
int arr[3][2]; //Declaration of array
Initialization of multidimensional array
arr[0][0]=1;
arr[0][1]=2;
arr[1][0]=3;
arr[1][1]=4;
arr[2][0]=5;

History Of C..

In the beginning was Charles Babbage and his Analytical Engine, a machine
he built in 1822 that could be programmed to carry out different computations.
Move forward more than 100 years, where the U.S. government in
1942 used concepts from Babbage’s engine to create the ENIAC, the first
modern computer.
Meanwhile, over at the AT&T Bell Labs, in 1972 Dennis Ritchie was working
with two languages: B (for Bell) and BCPL (Basic Combined Programming
Language). Inspired by Pascal, Mr. Ritchie developed the C programming
language.

My 1st Program...


#include
#include
void main ()
{
clrscr ();
printf ("\n\n\n\n");
printf ("\t\t\t*******Pankaj *******\n");
printf ("\t\t\t********************************\n");
printf ("\t\t\t\"Life is Good...\"\n");
printf ("\t\t\t********************************");
getch ();
}

Next Step...


#include
#include

void main ()
{
clrscr ();
printf ("\n\n\n\n\n\n\n\n");
printf ("\t\t\t --------------------------- \n\n");

printf ("\t\t\t | IGCT, Info Computers, INDIA | \n\n");
printf ("\t\t\t --------------------------- ");

getch ();

}

Hits!!!
