Post subject: something useless

While doing stuff i just made 2 functions which are kind of weird i guess, i just wanted to make them and they might be useful

MakeCapital() just changes a char from lower case to upper case, example "bob" will become "BOB"

Pause() will do same as system("pause"); just you can make any message like "bla bla"...

Code: Show/Hide

#include <stdio.h>
#include <windows.h>

char* MakeCapital(char* buf,int size)
{
for(int i=0;i<size-1;++i)buf[i]-=32;

return buf;
}

void Pause(const char* buf)
{
printf("%s",buf);

bool paused=true;

while(paused)for(int i=0x08;i<0xFE;++i)if(GetAsyncKeyState(i))paused=false;
}

int main()
{
char bob[] = "bob";

printf("%s",MakeCapital(bob,sizeof(bob)));

Pause("\nPress a key!!!");
}

Hmmm...
For Pause(), You could of used getch(), it gets the next input, but doesnt output it.

This a string-to-caps function I think, there certainly is one for php.

But still, great ideas.

toupper will convert characters to their uppercase equivalent without changing things like '1' or '-'.

As Brain said, toupper() already does that, but there are 2 things you could improve/fix in your MakeCapital function:

First, you don't need the size... A string is always ended by '\0' (a character with the value 0). So you r continuing condition can be when buf[i] != 0, or even simplier, if buf[i]. If buf[i] is non-null, evaluating "buf[i]" will return true

Code: Show/Hide

char* MakeCapital(char* buf)
{
for(int i=0; buf[i];++i )
buf[i]-=32;

return buf;
}

Also, if you don't want characters that are already upper-case, or non-letter characters to be changed by this, you need to add a little if in there...

Code: Show/Hide

char* MakeCapital(char* buf)
{
for(int i=0; buf[i];++i )
if (buf[i] >= 'a' && buf[i] <= 'z')
buf[i]-=32;

return buf;
}

And yeah, for pause, i think the function is 'getchar()'
Your function probably eats a shitload of CPU :/

toupper only converts a single char, so you'd still need a for loop like the one you've got.

oh, I thought there was one for strings... There's one defined in Mervbot anyway
