random number function

random

hi everyone.

i have this problem. i was making a simple monopoly simulator and i needed a function that would generate random numbers from 1 to 6. i searched the net for the rand() func and yes it was working but the problem in my code that every time I run it, it seems to generate the same number over and over again though it still gives me numbers from 1 - 6.

#include <time.h>
#include <stdlib.h>
#include <stdio.h>
#include <conio.h>

int dice1(int iroll1);
int dice2(int iroll2);
main(){
int iDiceValue1, iDiceValue2,isumdice;
int iVal1=0, iVal2=0, again=0;
int ilocate=0;
do
{
iDiceValue1 = dice1(iVal1);
iDiceValue2 = dice2(iVal2);
isumdice = iDiceValue1 + iDiceValue2;

printf("\n%d \t ",isumdice);
ilocate = ilocate + isumdice;
if(ilocate>39){
ilocate = ilocate % 10;
}


if(ilocate==0)
{
printf("GO");

}
else if(ilocate==1)
{
printf("HILLSIDE AVENUE");

}
again++;
getch();

}
while(again!=100);
}

int dice1(int iroll1){

 int irollvalue1 = rand();
 irollvalue1= (irollvalue1 % 6) + 1;
return irollvalue1;
}

int dice2(int iroll2){

 int irollvalue2 = rand();
 irollvalue2= (irollvalue2 % 6) + 1;
 return irollvalue2;
}

could someone explain why it functions like that and what solutions/changes can you offer.

sorry for my bad coding skills. im still learning :) thank you for understang. Have a good day.
