Hello
I got some C++ Sourcecode that I would like to rewrite into Objective C. It would help me alot if someone could write me a header file for this Code. When I get the Headerfile I would be able to rewrite the rest of the Sourcecode.
It would be very nice if someone could help me please.
Thanks
I will poste the sourcecode here:
#include <stdlib.h>
#include <iostream.h>
#define STATES 5
int transitionTable[STATES][STATES];
// function declarations:
double randfloat (void);
int chooseNextEventFromTable (int current, int table[STATES][STATES]);
int chooseNextEventFromTransitionTablee (int currentState);
void setTable (int value, int table[STATES][STATES]);
//////////////////////////////////////////////////////////////////////////
int main(void) {
int i;
// for demo purposes:
transitionTable[0][0] = 0;
transitionTable[0][1] = 20;
transitionTable[0][2] = 30;
transitionTable[0][3] = 50;
transitionTable[0][4] = 0;
transitionTable[1][0] = 35;
transitionTable[1][1] = 25;
transitionTable[1][2] = 20;
transitionTable[1][3] = 30;
transitionTable[1][4] = 0;
transitionTable[2][0] = 70;
transitionTable[2][1] = 0;
transitionTable[2][2] = 15;
transitionTable[2][3] = 0;
transitionTable[2][4] = 15;
transitionTable[3][0] = 0;
transitionTable[3][1] = 25;
transitionTable[3][2] = 25;
transitionTable[3][3] = 0;
transitionTable[3][4] = 50;
transitionTable[4][0] = 13;
transitionTable[4][1] = 17;
transitionTable[4][2] = 22;
transitionTable[4][3] = 48;
transitionTable[4][4] = 0;
int currentState = 0;
for (i=0; i<10; i++) {
std::cout << currentState << " ";
currentState = chooseNextEventFromTransitionTablee(currentState);
}
return 0;
};
//////////////////////////////////////////////////////////////////////////
//////////////////////////////
//
// chooseNextEventFromTransitionTable -- choose the next note.
//
int chooseNextEventFromTransitionTablee(int currentState) {
int targetSum = 0;
int sum = 0;
int targetNote = 0;
int totalevents = 0;
int i;
currentState = currentState % STATES; // remove any octave value
for (i=0; i<STATES; i++) {
totalevents += transitionTable[currentState][i];
}
targetSum = (int)(randfloat() * totalevents + 0.5);
while (targetNote < STATES &&
sum+transitionTable[currentState][targetNote] < targetSum) {
sum += transitionTable[currentState][targetNote];
targetNote++;
}
return targetNote;
}
//////////////////////////////
//
// randfloat -- returns a random number between 0.0 and 1.0.
//
double randfloat(void) {
return (double)rand()/RAND_MAX;
}
//////////////////////////////
//
// setTable -- set all values in the transition table to the given value.
//
void setTable(int value, int table[STATES][STATES]) {
int i, j;
for (i=0; i<STATES; i++) {
for (j=0; j<STATES; j++) {
table[i][j] = value;
}
}
