Thread: help with random function

i got a friend thats writing some c++ right now and he needs some help with a random function. he has a text file and it has 222 words in it but he needs to know how to make a random function that will take a number between 1 and 222 and pull the word in that line of the text file and use the word it pulled as the word. And btw hes making hangman if u need to know

and he's using dos not a gui

1) Get the random number in the proper range

2) Use the >> operator in a while loop conditional to read in words from the file, e.g.:

Code:

while(inFile>>word)
{
    ...
}

3) Keep looping until a loop counter reaches the random number, then break out of the loop, and 'word' will contain the word you want.

Use <fstream>, rand() and srand()

rand() and srand() are in <cstdlib>.
