And the error is:

In function 'int myRand()':
Line 315: error: call of overloaded 'pow(int&, int)' is ambiguous
compilation terminated due to -Wfatal-errors.


How can we fix this problem?

Thanks in advance.
Call pow in such way

pow( (double) random, 3 );
Use for example

int random2=pow( ( double )random, 3.0 );

I tried, now it's sayin' pow's in getRange function is ambigious.(line 176,177,179)
Make sure it says 3.0 and not just 3 as the decimal point is important.
try like this

1
2
3
4
number1=number/pow( 10.0, i - startIndex + 2);
number2=number1*pow(10.0, i - startIndex + 2);
number3=number - number2;
number4=number3/pow(10.0, i - endIndex + 1);
try: addin .0 to 10 ie number1=number/pow(10.0, i - startIndex + 2);
Thank you all, now it's working. :)
@TTT if startIndex and/or endIndex are integers, it will be ambiguous. It needs to use double there too - as simple as using 2.0 and 1.0
I try
number1=number/pow(10.0, i - startIndex + 2);

and there is no any compile-error

LB,

Is it not
double pow (double base, double exponent );
or
double pow (double base, int exponent );

Whoops - my mistake. I get various programming languages confused sometimes.
