Type writer effect...

Probably been asked before, but does anyone know how to do a type writer effect? Like puts one letter at a time until it spells a word? thanks

I do it this way:

Code:

---

#include <iostream>
#include <windows.h>
using namespace std;

int main(){
    char word[50] = "This is gonna be displayed slowly";
    slowtype(word);

    return 0;
}


void slowtype(char* word){

        for (int i = 0; word[i] != '\0'; i++){
                cout << word[i];                      //output a letter
                Sleep(70);                            //wait for a small moment
        }  //outputs text slowly
       
        Sleep(30);                       
                 
} //end void slowtype

I experimented with making it more random gaps...but rand doesn't like to work very randomly, so i did some crap to make the outcomes different....it's a littel better than using just rand....try it and see if you like it, there's plenty of room to improve but i only felt like spending 5 minutes:

Code:

---


#include <iostream>
#include <windows.h>
#include <conio.h>
#include <time.h>
using namespace std;

char sentence[]="This is a sentence.";
char * pointer=sentence;
int timeToWait;
int i;
int x;
int negate=0;
int typeWriter(char*);

int main()
{
        typeWriter(pointer);
        getch();
        return 0;
}

int typeWriter (char*)
{
        for (i=0;i<sizeof(sentence);i++)
        {
                timeToWait=0;
                srand(unsigned(time(NULL)));
                timeToWait=rand()%1000;
                if (timeToWait<70)
                {
                        timeToWait=70;
                }
                x=rand()%3;
                if (x<1)
                {
                        x=1;
                }
                switch (x)
                {
                case 1:
                        negate=0;
                        break;
                case 2:
                        negate=1;
                        break;
                }
                if (negate==0)
                {
                        timeToWait=timeToWait-200;
                }
                else
                {
                        timeToWait=timeToWait+200;
                }
                Sleep(timeToWait);
                std::cout<<sentence[i];
        }
        return 0;
}

im just crazy i guess :)

did you try randomize(); ?
it makes random stuff a lot better.

>>randomize();

im intrigued...tell me more :)

I think it is found in stdlib.h. Well its the one with the random command in it.

Anyways, if you output a random number without using the randomize command in a program and run it twice, the number will be the same.

Use "randomize();" in your code before the random function and the numbers will change. I think it sets them to an algorithim.

This is the case with my compiler: Borland Turbo C++. Dunno what it does for the dev compiler, im guessing the same tho.

sounds like a compiler specific thing....
mostly it sounds like it calls srand()
I use srand(unsigned(time(null)));
which sets the seed of rand with the internal clock so that it doesn't repeat numbers...but i noticed that mine repeat within a close range....is my calling srand more than once screwing it up or is that how i'm supposed to do it?

srand(GetTickCount())

get tick tiem:
what does taht do?
