Write a program that has three functions: main, add2, and mul2. Your main function will have a menu similar to the financial application you have been writing. The menu will have three items: “1) Add 2 numbers”, “2) Multiply 2 numbers”, “3) Quit”. When the user selects “Add 2 numbers”, call the add2 function. In add2, ask the user for two values, add them together and present the user with the result. Do a similar thing for the Multiply menu option, except in the mul2 function, multiply the two values you acquire from the user.

any help would greatly be appreciated

I have not actually tested the code so there might be bugs or syntax error, but the solution should be pretty similar to this.

<p>I have not actually tested the code so ......

What the hell is "iostream.h"? Secondly, you forgot the basics, like including "using namespace std;" - without that "cout" "and "cin" useless. There are so many other simple errors you would have found if you tested it, no major error tho, easy fixes. You even forgot the system("pause"); or getchar(); at the end lol. But the logic and syntax is correct. I fixed it tho, so here it is cool

• Our Maturity/Payment program should be able to run indefinitely allowing the user to run many loan
or maturity calculations.
• This looping continues until the user decides that he/she has calculated enough and presses a certain
key (let’s say ‘x’) to quit the program.
• Write the program once using the while loop with the if-else construct. (assign6a)
• Write the program a second time using the for loop with the switch construct. (assign6b)

can anyone help me with this?

^If I had more time I'd help you out. Just google C++ loop. Use an if statement to execute the exit sequence for the key to quit the program.

You need a 'while' statement.
Example:

while (userChoice !=x)
.........{
.......................lines of code
.......................lines of code
.........}

^That code will repeat whatever you place in the part that says "lines of code" until the condition is met, the condition being X.
You're basically saying, you will repeat everything over and over until the user inputs the letter x, which will terminate the loop. If you wait until Friday, I could write the entire thing in detail. (I think)

well i figured out how to do the "while loop" and "if else construct". how do i go about doing the "for loop" and "switch construct"?

http://pastebin.com/MiNKH4Lt
that is what i used for the while and if else

I don't think you should use for loop in this case. For loop should be used when you know how many times it is going to run. In this case, you don't, so while loop is better solution in this case.

You can replace your if-else to the following switch-case:

(I haven't tested the code, but the logic is correct.)

Is this valid or not? Explain. If correct what will be values of variables involved:

Code
int x = 15;
int *xp = x;
int *yp = *x;
int *zp = &amp;x;
int *wp = new int;
wp = 5;
*wp = 5;
&amp;wp = 5;
xp = wp;
*zp = 17;
float *fp = new float;
fp = wp;
*fp = (int) *wp;
zp = &amp;x;
float *fq = 5;

Details:
Start out with a new project (you can add code to it from your previous projects)
Create a class called [Calcs]. This class has two functions: [Add2] and [Multiply2]. Each function takes two parameters and returns the value of the calculation (either adds the two parameter values, or multiplies them).

Create an input file that contains data such as the following
A 2 3
M 5 7
A 6 11
A 2 22
M 79 62

Create a main function that opens the input file, reads each line, and based on the first character in the input line, calls the [A]dd function or the [M]ultiply function.
Once you have calculated the result (one line at a time), write the result to an output file.


Who can do this for me? Will send a little tip for you if you can do this smile

I've never used multi-dimensional arrays before, but I guess I could give it a try tomorrow.

Generically you could do it like this with a double loop.

&gt;&gt; user input

counter = 1; // determines the number of stars to print, initially
for( int i = 0; i &lt; user input; i++) {
for(int k = 0; k &lt; counter; k++) {
print *;
}
print \n;
counter++;
}

If correct you'll have the results
*
**
***
if the user input was 3
