How do we not generate the same number which has been generated in a loop? I need this because i'm doing a quiz game.

using only what u teached until now.
————————————————————–
{
int dice,sum1=0,sum2=0,i;
char answer;
for(i=0 ; i <4 ; i++)
{
dice = (rand()%6) + 1;
sum1 += dice;
}
printf("Your sum is: %d n",sum1);
puts("do you think, that the sum of the next drop will be higher,lower or same ? (h/l/s)");
scanf(" %c",&answer);for(i=0 ; i < 3 ; i++)
{
dice = (rand() % 6) + 1;
sum2 += dice;
}
printf("New sum is: %d nYou choose '%c'.",sum2,answer);
if ( ((sum1 > sum2) && (answer == 'l')) || ((sum1 == sum2) && (answer == 's')) || ((sum1 < sum2) && (answer == 'h')) ){
puts("Good For You! ");

i wanted a c language code for six digit random no. would you please help me.

After I read other codes, I realized that I misinterpreted the problem requirement.
I compared the number of the fourth dice roll withe the sum number of the prior three rolls.
Anyway, lazy to change, the principle is same. 🙂#include <stdio.h>

I did it easily guys. Check it out

srand(time(NULL));
printf(" %d n",0);
for(i=0; i<20; i++){
char guess;
printf("Guess what the next number would be(h/l/e): ");
scanf(" %c",&guess);
diceroll1=( rand()%6 ) + 1;

diceroll3=( rand()%6 ) + 1;
dicerollsum = diceroll1 + diceroll2 + diceroll3;

My cmd stops working on rand command. Help

But how do you generate numbers between some other starting point then 0? For example 75 to 105?
PLEASE GUYS HELP! -
Thanks for the tutorials 😉

What if we want to create more than one ranges like, we want it to give number from these three ranges
101-110
201-210
301-310? -
Here's my code for the challenge:

Here's my code for the challenge :

For those who are still wondering about a solution to challenge #2:
#include <stdio.h>
#include <stdlib.h>
#include <ctype.h>
#include <string.h>
#include <math.h>
#include <time.h>int main()
{
int dice1;
int dice2;
int dice3;
int dice4;
int dice5;
int dice6;
int diceTotal1;
int diceTotal2;
char userAnswer;
char userAnswer2;printf("tttaWelcome to the casino!!nn");
do{
printf("nPress any key to roll the dice!nn");
getchar();srand(time(NULL));
dice1 = (rand()%6) + 1;
dice2 = (rand()%6) + 1;
dice3 = (rand()%6) + 1;
diceTotal1 = dice1 + dice2 + dice3;printf("Dice1: %d nDice2: %d nDice3: %d nnTotal: %dnn", dice1, dice2, dice3, diceTotal1);
printf("If you guess your next dice roll is gonna be higher press (h).nIf you think it's gonna be lower press (l).nIf you think it's gonna be the equal press (e).n");
scanf("%c", &userAnswer);srand(time(NULL));
dice4 = (rand()%6) + 1;
dice5 = (rand()%6) + 1;
dice6 = (rand()%6) + 1;
diceTotal2 = dice4 + dice5 + dice6;printf("nDice1: %d nDice2: %d nDice3: %d nnTotal: %dnn", dice4, dice5, dice6, diceTotal2);
if((userAnswer == 'h' && diceTotal1 < diceTotal2) || (userAnswer == 'l' && diceTotal1 > diceTotal2) || (userAnswer == 'e' && diceTotal1 == diceTotal2))
{
printf("Very good. You guess right! nIf you want to try again press (1). If you want to leave press (0)n");
scanf(" %c", &userAnswer2);
}
else
{
printf("You guessed wrong. Try again! nIf you want to try again press (1). If you want to leave press (0)n");
scanf(" %c", &userAnswer2);
}}while(userAnswer2 != '0');
return 0;
}This solution allows the user to "play" the guessing game endlessly.
