Error

(1/1)

tiutea:
I tried example from Prata book and got error
CODE:


--- Code: ---#include<iostream>
#include <ctime>
#include <cstdlib>
#include "String.h"
const int MIN_PER_HR=60;
bool newcustomer(double x);
int main(){
    using namespace std;
    srand(time(0));

    return 0;
}


P.S. downloaded and installed codeblocks 16.01 on Win7

ollydbg:
Read the FAQ: My simple C++ program throws up lots of errors - what is going on?

stahta01:
I suggest posting a build log in code tags instead of build messages.

I also suggest removing the include of "String.h".
