Question

Your task: 1. Study Slides 24 -28 of “FunctionCalling.pptx” 2. Answer the following question in a separate file, called “Assignment#4.pdf”:

• Show all the possible outcomes of the experiment (rolling the dice) using a 2-D table. (see Slides 26, 27)

• What are the events (possible sums) such as 2, 3, … (See Slide 26, 27).

Example: Number Distribution so Generating numbers that conform a given distribution so Create an array to store all possible outcomes. int twodices[OUTCOME ]={2,3,4,5,6,7, 3,4,5,6,7,8, 4,5,6,7,8,9, 5,6,7,8,9,10, 6,7,8,9,10,11, 7,8,9,10,11,12}; Use rand() to generate random indices to access the outcome array. Example: in the following example, we use one more array, diceprob[EVENT], to record the frequencies corresponding to the outcomes: 2,3,4,5,6,7,8,9,10,11,12.

Answer 1

rand() function of the stdlib.h library generates a random integer.

Here is the C code for the generation of the random numbers and die sum frequency:-

#include <stdio.h>

#include <stdlib.h>

#include <time.h>

#define RUN 1000000

#define EVENT 11

#define OUTCOME 36

int main() {

int i, randNum, diceprob[EVENT]={0,0,0,0,0,0,0,0,0,0,0};

int twodices[OUTCOME]={2,3,4,5,6,7, 3,4,5,6,7,8, 4,5,6,7,8,9, 5,6,7,8,9,10, 6,7,8,9,10,11, 7,8,9,10,11,12 };

int dicerealprob[EVENT]={1,2,3,4,5,6,5,4,3,2,1};

srand(time(0)); // this is the seed given to the rand() function so that same set of random no. are not generated everytime we run the program

for(i=0;i<RUN;i++){ // running the simulation for RUN or 1000000 times

randNum= rand()%OUTCOME; // randNum would be a number between 0 and 35(both inclusive), that is the indices of the twodices array

diceprob[twodices[randNum]-2]++; // incrementing the corresponding outcome's frequency in diceprob array

}

for(int j=0;j<EVENT;j++){

printf("%d ",diceprob[j]);

}

}
