>>when I undefine an array like this can I populate the array again?
you are not undefining anything here.
When u define an integer or an array, most compilers initialize it with a value 0. So, we are making the contents of the array 0 by this method.
array is still valid, and u can use it.
To understand whats happening with this code, just print out the values of the array before and after this code. |

You can use either:
memset(yourarray, 0, sizeof yourarray);
or
for( int i = 0 ; i < sizeof( yourarray ) / sizeof( yourarray[ 0 ] ) ;
++ i ) {
yourarray[ i ] = 0 ; // or some other "clear" value
}
If it is a char array, just set the first element to '\0' |

I created the array dynamically through pointer decleration.
I tried
void free(void *ptr);
but no use.
any other suggestions.
There is no undefine in C I guess. |

am doing some very basic prog in C...
is there a way to undefine an array.
am reading from a file and populating an array...at the end of reading each line I'll check some condition..if it fails I want to clear the array.
How can I do this. |
