C array initialization
Syntax
C array initialization has the following format.
type arrayName[length] = {array elements};Example - Initializing an array in declaration
#include <stdio.h>
#define SIZE 12/*w w w . j a v a2 s . c om*/
int main()
{
int a[ SIZE ] = { 1, 3, 5, 4, 7, 2, 99, 16, 45, 67, 89, 45 };
int i;
int total = 0;
for ( i = 0; i < SIZE; i++ ) {
total += a[ i ];
}
printf( "Total of array element values is %d\n", total );
return 0;
}
The code above generates the following result.
Example - Initializing an array using for loop
#include <stdio.h>
//from www .ja v a 2s . co m
int main()
{
int n[ 10 ];
int i;
/* initialize elements of array n to 0 */
for ( i = 0; i < 10; i++ ) {
n[ i ] = 0;
}
printf( "%s%13s\n", "Element", "Value" );
for ( i = 0; i < 10; i++ ) {
printf( "%7d%13d\n", i, n[ i ] );
}
return 0;
}
The code above generates the following result.
