Ubuntu üzerinde bazı kod çalışıyorum. Aşağıdaki kod çalıştırmak için çalışıyorum

#include <cstdlib>
#include <cmath>
#include <ctime>
#include "random.h"

using namespace std;

/* Function prototype! */
void initRandomSeed();

int randomInteger(int low,int high){
    initRandomSeed();
    double d= rand()/(double(RAND_MAX) 1);
    double s= d*(double(high)-low 1);
    return int(floor(low) s);    
}

double  randomReal(int low,int high){
    initRandomSeed();
    double d=rand()/(double(RAND_MAX) 1);
    double s=d*(double(high)-low 1);
    return low s;
}    

bool randomChance(double p){
    initRandomSeed();
    return randomReal(0,1)<p;
}            

void setRandomSeed(int seed){    
    initRandomSeed();
    srand(seed);
}    

void initRandomSeed(){
    // to retain updated values across different stack frames! nice!
    static bool initialized=false;

    // this is executed only very first time and random value obtained from system clock!
    if(!initialized){
        srand(int(time(NULL)));
        initialized=true;
    }
}

Ve yukarıdaki kodu kullanarak derlemeye çalıştığımda g aşağıdaki hatayı alıyorum

Herhangi bir yardım veya yardıma gerçekten yardımcı olabilecek sorular bağlantılar! Teşekkürler!

Geçersiz yerleştirme Hataları konusunda emin değilim ama açık bir şey eksik main fonksiyon yok. Uygulamanız için bir giriş noktası olarak main, bu genel kapsamında tanımlanan adlı tanımlamak gerekir:

int main()
{
    // TODO: implementation
}
