Question

Write a program in C which randomly generates two integers X and Y between 10 and 50, and then creates a dynamic array which can hold as many numbers as there are between those two random numbers. Fill the array with numbers between X and Y and print it on screen. Do not forget to free the allocated memory locations whenever they are no longer needed.

Example:

Randomly generated numbers are: 43 23

Expected Output :

23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43

ANSWER:

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

int main(void) {
    
    
        int x, y, min, max;
        srand(time(0));  // using current time for seeding the random number generator.
        x = 10+rand()%41 ;  // Generate random number between 10 and 50
        y= 10+rand()%41;
        
        printf("Randomly generated numbers are: %d %d \n",x,y);
        int value = abs(y-x)+1;
    int *array= (int *)malloc(sizeof(int)*value);
    if(x<y){
        min = x;
        max = y;
    }
    else{
        min =y;
        max=x;
    }
    int c=0;
    for(int i=min;i<=max;i++){
        array[c] = i;
        c+=1;
    }
    int temp=0;
    for(int j=min;j<=max;j++){
        printf("%d ",array[temp]);
        temp+=1;
    }
    
    // Freed up dynamically allocated memory.
    free(array);
        return 0;
}
