Answer to Question #186464 in C for Muhammad Haris

Question

Write a program that prints the result of rolling one fair dice.

Hint: use the rand() function with range given in arguments to generate a random integer in the desired range.

Add a loop to print the sum of rolling 10 fair dice.

Add a second loop to repeat this N times, printing the sum after each trial.

Maintain an array count[] so that count[k] stores the number of times the sum is exactly k.

Review your code and eliminate glitches and unnecessary repetitions if any.

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

#define NO_OF_DICE	10
#define ITERATIONS 5
main(void)
{
	int Sum=0,n,t=0,k;	
	int Dice[NO_OF_DICE];
	int Sum_Itr[ITERATIONS];
    srand(time(0)); 
    printf("\nSolution-1: Rolling a fair dice %d times",NO_OF_DICE);
    for(n=0;n<NO_OF_DICE;n++)
    {
    	while(t<1 || t>6) t=rand();
    	printf("\nDice Roll No. %d = %d",n+1,t);
    	t=0;
	}
    printf("\n\nSolution-2: Sum of rolling %d fair dice",NO_OF_DICE);
    Sum=0;
    for(n=0;n<10;n++)
    {
    	while(t<1 || t>6) t=rand();
    	printf("\nDice Roll No. %d = %d",n+1,t);
    	Sum = Sum + t;
    	t=0;
	}
	printf("\nTotal Sum = %d",Sum);
    printf("\n\nSolution-3: Sum of rolling %d fair dice",NO_OF_DICE);
    Sum=0;
    for(k=0;k<ITERATIONS;k++)
    {	
    	Sum_Itr[k]=0;
    	for(n=0;n<NO_OF_DICE;n++)
		{
			while(t<1 || t>6) t=rand();	
			Sum_Itr[k] = Sum_Itr[k]+t;
	    	t=0;
		}
    	printf("\nSum of %d no. of fair Dices at Iteration No. %d = %d",NO_OF_DICE,k,Sum_Itr[k]);
	}
