Write a program that reverses the words in sentence.
Use a loop to read charactes one by one and store them in
one-dimensioal char array. Have the loop stop at a period,
question mark or exclamantion point and store it in separate
char varible. Then use a second loop to search backward through the array for the begging og the last word. Print the last word then search backward for the next-to-lat word. Repeat until beginning of the array is reached. Finnaly print the termination character.
I have a class with an integer pointer, which I have not initialized to NULL in the constructor. For example:
class myclass
{
private:
char * name;
int *site;
}
myclass:: myclass(....)
: name(NULL)

If one wants to get a start address of a array or a string or a block of memory via a function, there are at least two methods to achieve it:
(1) one is to pass a pointer-to-pointer parameter, like:
int my_malloc(int size, char **pmem)
{
*pmem=(char *)malloc(size);
if(*pmem==NULL)... (11 Replies)

play_midi
play_midi(3alleg4) Allegro manual play_midi(3alleg4)NAME
play_midi - Starts playing the specified MIDI file. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
int play_midi(MIDI *midi, int loop);
DESCRIPTION
Starts playing the specified MIDI file, first stopping whatever music was previously playing. If the loop flag is set to non-zero, the data
will be repeated until replaced with something else, otherwise it will stop at the end of the file. Passing a NULL pointer will stop what-
ever music is currently playing.
RETURN VALUE
Returns non-zero if an error occurs (this may happen if a patch-caching wavetable driver is unable to load the required samples, or at
least it might in the future when somebody writes some patch-caching wavetable drivers :-)
