count length of word without using inbuilt functions in c#

int myOwnGetStringLength(String str)
{
   int count = 0;
   foreach(Char c in str)
       count++;
   return count;
}

other way

private int stringLength(string str) {
       int length = 0;
       bool done = false;
       do {
           try {
               char c = str[length];
               length++;
           } catch (IndexOutOfRangeException) {
               done = true;
           }
       } while(!done);
       return length;
   }

A prime number is a natural number that has only one and itself as factors.

#include <stdio.h>

• main() {
• int n, i, c = 0;
• printf("Enter any number n: ");
• scanf("%d", &n);
• /*logic*/
• for (i = 1; i <= n; i++) {
• if (n % i == 0) {
• c++;
• }
• }
• if (c == 2) {
• printf("n is a Prime number");
• }
• else {
• printf("n is not a Prime number");
• }

return 0;}

HTTP Methods: GET vs. POST

Two commonly used methods for a request-response between a client and server are: GET and POST.

• GET - Requests data from a specified resource
• POST - Submits data to be processed to a specified resource

Some other notes on GET requests:

• GET requests can be cached
• GET requests remain in the browser history
• GET requests can be bookmarked
• GET requests should never be used when dealing with sensitive data
• GET requests have length restrictions
• GET requests should be used only to retrieve data

Some other notes on POST requests:

• POST requests are never cached
• POST requests do not remain in the browser history
• POST requests cannot be bookmarked
• POST requests have no restrictions on data length
