i was given an assignment to create a word construction game where the program will randomly picks a combination of vowels and consonants and the user will build as much words as possible from the choosen letters. my prog will check for the correctness of the words and gives the user points to each word built, with higher point given to words that use all the letters. i limited the number of letters to 4 or 5 letters only. i justtttt learned programming from the intro up to the string topic. so , i havee no idea how to create this game. can anyone help me with this ? i'm currently using dev c++ 5.5.3. someone pleasee help me with this :( and i also need some help on the calculations of marks.

my program is almost finish but how can i let my prog randomly pick the question ?

First, you need to be able to generate a random number (int) within your stored question array. In this case, I believe you set it to 30, so the number should be from 0 up to 29 (inclusive). You should read this page on how to use rand() function in order to get a number in a range.

Here is how I might start to tackle a problem like this ...

Note the comments in the program to find all the .h files needed to test it out.

You can find file "CvecOfString.h" at:
http://developers-heaven.net/forum/index.php/topic,2580.msg2865.html#msg2865

You can find file "readLine.h" at:
http://developers-heaven.net/forum/index.php/topic,2580.msg2864.html#msg2864

You can find file "Cvec.h" at:
http://developers-heaven.net/forum/index.php/topic,2580.msg2862.html#msg2862

The following program assumes that you already have a big dictionary text (.txt) file (pre-fixed, sorted and all lower case words) available.

/* makeWordsFromLetters.c */  /* 2018-09-19 */


#include <time.h> /* re. srand( time(0) ); */

                             which also include ... (look in files, to see) */
