What is the difference between these two:

int & n2 = n;

int *n3 = & n;

and these two:

int * q = p;

int n = *p;

The question :

Write a program that will initialize an array of charters to “do be do bo”. The program will call function Statistics() to output a list of all letters that occurred in the array together with the number of times each letter occurs in the array.

The output should look similar to:

The array is: do be do bo

Letter Number of occurrence

d 2

o 3

b 2

e 1

Letter ‘o’ has occurred the most.

The function prototype is:

void Statistics (char a []);

My program:

#include <iostream>

#include<iomanip>

using namespace std;

void Statistics (char a []);

int main()

{

char d[]="do be do bo";

Statistics(d);

return 0;

}

void Statistics (char d [])

{

int freq[26] ={0};

int i=0;

while ( d[i]!='\0')

{

if (d[i]==' ')

{

i++;

continue;

}

else

(freq(d[i]-97))++; //ERROR ONE called object type int is not a function

i++;

}

for (int j=0; j<26; j++)

{

cout<<setw(10)<<"Letter"<<setw(20)

<<"Number Of Ocurance\n";

cout<<setw(10)<<d[j]<<setw(20)<<

freq(d[i]-97); // ERROR TWO called object type int is not a function

}

}

How do I convert the charecter to an integer?

I'm using autocad 2011 on a mac.

I'm using a mac, and i know how to set the drawing limits to 0,0 210,297 , but whenever i want to draw a rectangle it just does not appear on the screen, the screen is all black, i did zoom all, but nothing appears.

And tell me which template to use, in college they use (Start from scratch), but they use an older version i think. I need the equivalent of that.

I am 162 cm tall and i weigh 50 Kilo grams, I only want to have a less "wiggle" in my butt and thighs (tighten my body), what workout routine should i follow ? and is it better to workout before or after i eat? I'm clueless about this since i have never worked out in my life, by my own will i mean :)

I downloaded PSX games with a ".7z" extension, and i want to able to play them on my macbook using an emulator(i googled it but didn't get it), how does that work ??

What is the net magnetic field 23.0 due west of the wire if the Earth's field there points downward, 44 below the horizontal, and has magnitude ?

And what is Theta ??

If u can show me calculations that would be appreciated :)

how do i determine how many atoms are on the Br atom ??

I really liked physics 1, and i'm pretty good at all the other science subjects except for physics 2,

I'm applying for civil engineering, but i have to have a second choice (backup), my options are:

Computer

Electrical

Chemical

Petroleum

Industrial

Mechanical

i can't draw the lewis structure of it, how do i determine how many free atoms are on Br ??

Please include details :)

my hair is four inches under my shoulder and without layers, yet my regular ponytail wont stay in place.. any tips are appreciated ;)

im not from the us i just need to convert and im not getting the whole central central and eastern, ill do the math from chicago thanks....

i need 3 flashes, what should i choose?

i wanna use them as a studio flashes, for portraiture, and for some indoor sports, and i have an eos 7d so i dont have to worry about the 580ex controlling the other 430's, i can just control them all in camera..

and how do you know the difference between speedlights? what should i look for ? i want one that supports my Canon 7D's built in wireless flash

i know both are different but this is my first dslr and really like the f1.4 but the zoom lens is pretty impressive, my question is what are the good and bad sides to each lens?
