This guys think say we never wise..How can i be designing things worth millions of naira for you and you will pay me just 150k.. think of it this way, if i develop two software for you worth 8M in a month am only entitled to 150k..which way nah Naija?

#include <stdio.h>
#include <math.h>

void main() {
  int num = 101;
  double sq;
  int whole;
  do {
    num++;
    sq = sqrt(num);
    whole = (int)sq;
  } while ((sq - whole) > 0);
  printf("perfect square is %d\n", num);
}

perfect square is 121

can you please help me with the solution to this?

$count = 1;
$num = 2;
$index = 10001;

function isPrime($num) {
    static $m = [];
    foreach ($m as $i) {
        if (is_int($num/$i)) {
            return false;
        }
    }
    $m[] = $num;
    return true;
}

while (true) {
    if (isPrime($num)) {
        echo "$num is prime $count\n";
        $count++;
    }
    if ($count == $index) { break; }
    $num++;
}
echo "prime $num is count of $count\n";

<?php
$count = 0;
$num = 2;
$index = 10001;

function isPrime($num) {
    for($i = 2; $i < $num; $i++) {
        if (is_int($num/$i)) {
            return false;
        }
    }
    return true;
}

while (true) {
    if (isPrime($num)) {
        echo "$num is prime $count\n";
        $count++;
    }
    if ($count == $index) { break; }
    $num++;
}
echo "prime $num is count of $count\n";

Have you been coding PHP for many years but have not gone beyond few functions?, this thread tests your practical knowledge of the language.
Please, don't post off-topic here, just serious contributions involving code and useful comments..

I'd take this from easy to hard and anybody can drop in a question at anytime.

Now, first question:

$first_string = 'DanielTheGeek' ;
$second_string = 'Daniel' ;
if (strpos($first_string, $second_string)) {
echo "\"" . $first_string . "\" contains \"" . $second_string . "\"" ;
} else {
echo "\"" . $first_string . "\" does not contain \"" . $second_string . "\"" ;
}

If you run the above code, you'd get:
"DanielTheGeek" does not contain "Daniel"

Why?

What needs to be changed to make the above code work as expected?
