Question

Write a C program that stores N random numbers in an array named rA[ ] and determine the largest, smallest, and average values of this array. Display the array elements that store these values. The random numbers range from -50 to +50. N is a command line argument.

Answer 1

Answer:

// program in C.

// headers

#include <stdio.h>

// headers

#include <stdlib.h>

// headers

#include <limits.h>

// main function

int main(int argc, char** argv)

{

   // read value of N from command line arguments

   int N=atoi(argv[1]);

   // variables

   int max=INT_MIN;

   // variable

   int min=INT_MAX;

int rA[N],i;

// fill the array with random number

for(i=0;i<N;i++)

{

    // generate random number from -50 to +50

    rA[i]=rand()%101-50;

    // find the Maximum

    if(rA[i]>max)

    max=rA[i];

    // find the Minimum

    if(rA[i]<min)

    min=rA[i];

}

// print values of array

printf("values of the array are:");

for(i=0;i<N;i++)

{

    printf("%d ",rA[i]);

}

// print Maximum

printf("\nMaximum value is:%d",max);

// print Minimum

printf("\nMinimum value is:%d",min);

return 0;

}

Explanation:

Read value of N from command line.Then create an array of size N.Fill the array with random number from -50 to +50.Then find the Maximum of all the elements and  assign it to variable "max" and find Minimum from all and assign it to variable "min". then print all the elements of the array, Minimum and Maximum.

Output:

command line argument=10

values of the array are:-18 -18 4 -38 2 6 -42 -20 -6 44 -6 -11 15 -31 1                                                    

Maximum value is:44                                                                                                        

Minimum value is:-42
