Question

In probability class there are 140 students, with 90 of them being from Industrial engineering, 10 from EEE, 10 from CoE, 10 from BME and 20 from CE departments. The professor picks a student randomly and asks for his department and then he writes down the student department. Simulate this scenario in C programming language.

Answer 1

Points to consider.

1. We will find a random number from 1 to 140 and then we can divide the ranges for each of the departments based on the number of students in each.
2. Then we need to print the department found.

Code:

#include<stdio.h>
#include<stdlib.h>
#include<time.h>
int main(){
   // Adding the seed to the random function
   srand(time(0));
   // Getting the random number
   int num = rand()%140 + 1;
   // For storing the dept
   char *dept;
   if(num <= 90){
       dept = "Industrial engineering";
   }else if(num <= 100){
       dept = "EEE";
   }else if(num <= 110){
       dept = "CoE";
   }else if(num <= 120){
       dept = "BME";
   }else{
       dept = "CE";
   }
   // Printing the randomly generated department
   printf("Department: %s", dept);
}
