1. Write a C Program to generate the Fibonacci series n number of times.
#include <stdio.h>
int main() {
int n, i;
int a = 0, b = 1, next;
printf("Enter number of terms: ");
scanf("%d", &n);
printf("Fibonacci Series:\n");
for(i = 1; i <= n; i++) {
printf("%d ", a);
next = a + b;
a = b;
b = next;
}
return 0;
}
Input: 5 Output: Fibonacci Series: 0 1 1 2 3
2. Write a program that take input an array with positive and negative number and rearrange this with positive to negative.
#include <stdio.h>
int main() {
int n, i, pos[100], neg[100];
int p = 0, ne = 0;
printf("Enter number of elements: ");
scanf("%d", &n);
int arr[100];
printf("Enter elements:\n");
for(i = 0; i < n; i++) {
scanf("%d", &arr[i]);
}
// Separate positive and negative numbers
for(i = 0; i < n; i++) {
if(arr[i] >= 0)
pos[p++] = arr[i];
else
neg[ne++] = arr[i];
}
// Rearrange: positives first, then negatives
printf("Rearranged array:\n");
for(i = 0; i < p; i++) {
printf("%d ", pos[i]);
}
for(i = 0; i < ne; i++) {
printf("%d ", neg[i]);
}
return 0;
}
Input: 5 1 -2 3 -4 5 Output: Rearranged array: 1 3 5 -2 -4
3. Write a program that takes input for date, month, and year, and verifies if the given date is valid. If valid, display "Valid Date", otherwise display "Invalid Date". Also, explain how leap years are handled in your program.
#include <stdio.h>
int isLeapYear(int year) {
if ((year % 4 == 0 && year % 100 != 0) || (year % 400 == 0))
return 1;
return 0;
}
int main() {
int day, month, year;
int valid = 1;
printf("Enter day month year: ");
scanf("%d %d %d", &day, &month, &year);
// Check month validity
if (month < 1 || month > 12)
valid = 0;
// Days in months
int daysInMonth[] = {31,28,31,30,31,30,31,31,30,31,30,31};
// Adjust February for leap year
if (isLeapYear(year))
daysInMonth[1] = 29;
// Check day validity
if (day < 1 || day > daysInMonth[month - 1])
valid = 0;
if (valid)
printf("Valid Date\n");
else
printf("Invalid Date\n");
return 0;
}
A year is considered a leap year if: • It is divisible by 4 but not divisible by 100, OR • It is divisible by 400 In the program, February (month = 2) is assigned 29 days instead of 28 when the year is a leap year.
4. Given an IP address 10.10.250.0/24. Find total number of computer connected in a network and list of network ID
Given:
IP address = 10.10.250.0/24
Subnet mask: /24 = 255.255.255.0
Total number of IP addresses:
232-24 = 28 = 256
Total number of computers (usable hosts): 256 – 2 = 254
Network ID: 10.10.250.0
Broadcast address: 10.10.250.255
Usable host range: 10.10.250.1 to 10.10.250.254
Total connected computers = 254
Network ID = 10.10.250.0
