  1. import datetime While True: my_now = datetime.datetime.now().strftime("%d.%b %Y %H:%M:%S") myfile = open("my_file.txt", "a") myfile.write("Added at {my_now}") myfile.close() sleep (100)
  2. #include <stdio.h> int main(){ for(int i = 0x20; i<0x30; i++){ printf("%d ", i); printf("%c\n", i); } }
  3. int a = 6; int b = 2; std::cout << "a=" << a << " b=" << b << "\n"; int temp = a; a = b; b = temp; std::cout << "a=" << a << " b=" << b << "\n";
  4. #include <stdio.h> #include <time.h> int main(){ time_t ct; // current time struct tm *lt; // local time ct = time(NULL); lt = localtime(&ct); printf("%s\n", asctime(lt)); }
  5. #include "../x11.c" int main(){ xopen(0,0,"box"); xclear_color(ORN); xcolor(BLU); xrectangle(44,44,200,100,0); xgetc(); xclose(); }
  6. typedef struct { int x; int y; } point_t; point_t some_func(void) { point_t pt; pt.x = 0; pt.y = 0; return pt; }
  7. Yes if (someValue == someOtherValue) { someFunction(); }
  8. The floatval() function return the float value of the variable passed to it. For example: $integer = 123; $float = floatval($integer); var_dump($integer); // int(123) var_dump($float); // float(123)
  9. Here is the example: void foo(void) { printf(“foo was called\n”); } if you do this: foo(); then you’re calling do by name. If you do: void (*func_ptr)(void) = foo; func_ptr(); Then you’re calling foo through function pointer func_ptr().
  10. void f(int i) { i = i + 1; } void g(int &i) { i = i + 1; } int main() { int i = 1; f(i); // by value: i is still 1 g(i); // by reference: i is now 2 return 0; }
  11. int x[] = {1,2,3,4}; void print(int *arr, size_t n) { for (size_t i = 0; i < n; i++) { printf(“%d\n”); } } print(x, 4);
  12. #include <stdio.h> int main() { for (int a=20;a>=10;--a){ // Write C code here printf("Hello world"); } return 0; }
  13. int x[] = {1, 2, 3, 4}; You could also use a length: int x[4] = {1, 2, 3, 4};
  14. int x[] = {1, 2, 3, 4}; You could also use a length: int x[4] = {1, 2, 3, 4};
  15. print("Now is the winter ",end ="") # no line feed print("of our discontent") # yes Line Feed print("Made glorious summer",end="") print(" by this sun of York;") print("And all the clouds that ",end="") print("lour'd upon our house") print("In the deep bosom of",end="") print(" the ocean buried.") Output Now is the winter of our discontent Made glorious summer by this sun of York; And all the clouds that lour'd upon our house In the deep bosom of the ocean buried.
  16. // One of these things is not like the others. // One of these things just doesn't belong. String[] items = new String[] { "Apple", "Orange", "Spider", "Banana", }; // Note that you CAN use a comma after the last item! // This is a convenience if you need to re-order the items.
  17. for (int i = 0, j = 0; i < 5; ++i, ++j) { std::cout << i << ' ' << j << '\n'; }
  18. $array = [1, 2, 3, 4, 6, 7, 8]; $from = 2; // array offset 1 $to = 4; // array offset 4 $sum = 0; for($i = $from; $i <= $to; $i++ ){ $sum = $sum + $array[$i]; } echo $sum; // 15
  19. #include <stdio.h> #include <time.h> int main(){ time_t ct; // current time struct tm *lt; // local time ct = time(NULL); lt = localtime(&ct); printf("%s\n", asctime(lt)); }
  20. #include <stdio.h> int main(){ char *str1 = "abc"; char str2[] = "def"; printf("%s - %s\n", str1, str2); }
  21. Use array indices instead. int arr[5] = {11, 22, 33, 44, 55}; for (int i = 0; i < 5; i++) { printf(“arr[%d] = %d\n”, i, arr[i]); }
  22. <script> $( "div, span, p.myClass" ).css( "border", "3px solid red" ); </script>
  23. A function can return a value of any datatype that is available in PHP. function returnArray(){ $arr = [2, 4, 6]; return $arr; } /* * outputs: * Array( [0] => int(2) [1] => int(4) [2] => int(6) ) */ var_dump(returnArray());
  24. You can use media query CSS to make a website responsive without using any third party tools. Example code: <!DOCTYPE html> <html> <head> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <style> * { box-sizing: border-box; } .row::after { content: ""; clear: both; display: block; } [class*="col-"] { float: left; padding: 15px; } html { font-family: "Lucida Sans", sans-serif; } .header { background-color: #9933cc; color: #ffffff; padding: 15px; } .menu ul { list-style-type: none; margin: 0; padding: 0; } .menu li { padding: 8px; margin-bottom: 7px; background-color: #33b5e5; color: #ffffff; box-shadow: 0 1px 3px rgba(0,0,0,0.12), 0 1px 2px rgba(0,0,0,0.24); } .menu li:hover { background-color: #0099cc; } .aside { background-color: #33b5e5; padding: 15px; color: #ffffff; text-align: center; font-size: 14px; box-shadow: 0 1px 3px rgba(0,0,0,0.12), 0 1px 2px rgba(0,0,0,0.24); } .footer { background-color: #0099cc; color: #ffffff; text-align: center; font-size: 12px; padding: 15px; } /* For desktop: */ .col-1 {width: 8.33%;} .col-2 {width: 16.66%;} .col-3 {width: 25%;} .col-4 {width: 33.33%;} .col-5 {width: 41.66%;} .col-6 {width: 50%;} .col-7 {width: 58.33%;} .col-8 {width: 66.66%;} .col-9 {width: 75%;} .col-10 {width: 83.33%;} .col-11 {width: 91.66%;} .col-12 {width: 100%;} @media only screen and (max-width: 768px) { /* For mobile phones: */ [class*="col-"] { width: 100%; } } </style> </head> <body> <div class="header"> <h1>Bangladesh</h1> </div> <div class="row"> <div class="col-3 menu"> <ul> <li>The Flight</li> <li>The City</li> <li>The Island</li> <li>The Food</li> </ul> </div> <div class="col-6"> <h1>The City</h1> <p>Bangladesh is the capital of the Bangladesh region on the island of Crete.
