help you fix your problem The substring() function extracts part of string (from the column attribute_name) from the position numbered x for y characters (or until position x + y - 1). For instance 1 to 3 would be the first three characters.
This is then converted to an integer and compared to another value.

Is it safe to cast pointer to integer, increment that integer, and cast back?

it helps some times This is implementation-defined behaviour. Your compiler should document whether or not pointer arithmetic is equivalent to integer arithmetic on the converted numeric values of pointers. That should be the case on modern computers with a "flat" byte-addressed memory space; but it's not guaranteed to work portably on all platforms.
Using char* rather than uintptr_t will work portably, as long as you stay within the array and ensure the pointer is correctly aligned for T before converting back.

it fixes the issue My scenario is that i have duplicate substring with string in column like , Try this:
code :
SELECT SUM(CAST(SUBSTR(t.YourColumn, LOCATE('-',t.YourColumn)+1) as INT)) as sum_total
FROM YourTable t

hop of those help? String replacement pattern cannot be interpolated for use as variables to a method.
You may use a match evaluator:
code :
Dim rx = New Regex("f\((\d+),([a-zA-Z0-9_\s]+),([a-zA-Z0-9_\s]+)\)")
Dim result = rx.Replace(s, New MatchEvaluator(Function(m As Match)
         Return myLittleFunction(Convert.ToUInt32(m.Groups(1).Value), m.Groups(2).Value, m.Groups(3).Value)
     End Function))

cast from pointer to integer of different size and assignment makes integer from pointer without a cast

To fix the issue you can do There's a couple of issues in your code.
First you're casting the result from malloc() to a char and not a char*. This is what is causing the error your question refers to.
code :
void KnightsFlip( FILE * fin, FILE * fout )
    int num;
    fscanf( fin, "%d", &num );
    fprintf( fout, "KnightsFlip:\n" );
    char *string;
    string = ( char* ) malloc( ( num + 1 ) * sizeof( char ) );
    if ( string == NULL )
        printf( "Not Memory found" );
        string[num] = '\0';
        KnightsFlipRecursion( string, 0, num, fout );
        fprintf( fout, "\n" );
        free( string );

To insert a substring in the given string:Error:15 [Warning] return makes integer from pointer without a cast

it helps some times Strings are usually represented as char arrays i.e. char[] or char*. Since you are returning a string from the function, the return type should be char*.
