Question

Write a single C program within which you generate n random integers and store them in an array A.

Note:
- n is a keyboard input that must be greater than 10.
- Must implement a sanity check for n to ensure it is greater than 10 . And if it is not, it should keep asking for a new value of n.
- The maximum value of any randomly generated integer is 5.

Answer 1

The program snippet provided generates n random integers and stores them in an array, after verifying that n is greater than 10 through a do-while loop. It uses the rand function to create random numbers with a maximum value of 5.

Step-by-step explanation:

Creating an Array with Random Numbers in C

In order to generate an array of n random integers, where n is an input greater than 10, we use a simple C program. It includes a sanity check to ensure the user enters a correct value for n. The program uses the rand function to generate random integers with a maximum value of 5. The code structure involves a loop for continuous prompting until a valid number is provided and another loop for populating the array with random integers.

Program Snippet

Notes: The following code assumes that srand(time(NULL)) is called earlier in the main function to seed the random number generator with the current time, making the random numbers differ from run to run.

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

int main() {
int n;
do {
printf("Enter a number greater than 10: ");
scanf("%d", &n);
} while(n <= 10);

int A[n];
for(int i = 0; i < n; i++) {
A[i] = rand() % 6; // Generates a random number between 0 to 5
}

// Output the array or process as required
for(int i = 0; i < n; i++) {
printf("%d ", A[i]);
}
return 0;
}
