Lab 1 Output Numbers In Reversewrite A Program That Reads A List Of

Develop a program that reads an integer indicating the number of integers that follow, then reads that many integers into an array, and outputs them in reverse order. Each output integer should be followed by a space, including the last one. Assume the list contains fewer than 20 integers.

Introduction

The task involves reading a list of integers and then displaying the list in reverse order. This straightforward operation serves as an excellent exercise for understanding array handling and basic I/O in programming.

Implementation Details

First, the program prompts the user or receives input indicating how many integers will be entered. It then reads these integers into an array. To reverse and output the list, the program iterates through the array backwards and prints each element followed by a space. Ensuring that the output for each integer is separated by a space maintains readability and adheres to the specifications.

Sample Code

include <stdio.h>
int main() {
int n, i;
int arr[20];
// Read the number of integers
scanf("%d", &n);
if (n >= 20) {
printf("Input exceeds maximum allowed size.\n");
return 1;
}
// Read integers into array
for (i = 0; i 
scanf("%d", &arr[i]);
}
// Output integers in reverse order
for (i = n - 1; i >= 0; i--) {
printf("%d ", arr[i]);
}
return 0;
}

Conclusion

This simple program demonstrates fundamental array operations, including reading data, indexing, and reversing an array, which are essential skills in programming.
