I'm having trouble with making a nested if-else program for my computer programming class, I really need some help with getting the variables set up and I believe I can work it out from there, but as for right now I am stuck.

http://www.uwplatt.edu/csse/courses/CS143/prog1.html

here are the guidelines please pm me if you can help! I need to have this done before 10 PM tonight and I can provide some FG is someone is really helpful in getting me going the right direction.

I have some of the code written but I am a complete newbie so it could be all garbage.

Thanks!

Code

// Purpose: A program that converts between kilometers and miles

// Input: A character value of 'K' , 'M' , 'F' or 'C'.
// An int or float representing the amount.
//
// Output: A correct conversion between 'K' and 'M' or 'F' and 'C'
// An error message shown for incorrect input of character or
// an error if the temperature or distance is out of range.

const float MILES_PER_KM = 1.0f / 1.61f;
const float KM_PER_MILE = 1.61f;
const float FREEZING_F = 32.0f;
const float FAHR_PER_CELSIUS = 9.0f / 5.0f;
const float CELSIUS_PER_FAHR = 5.0f / 9.0f;
const float MAX_F_TEMP = 100.0f;
const float MIN_F_TEMP = 0.0f;

char k = 'K';
char m = 'M';
char f = 'F';
char c = 'C';

float unit;
float amount;

int main()
{
cout << " Input a type (K, M, F, C) : ";
cin >> unit;
cout << " Input an amount : ";
cin >> amount;

if ( unit == 'K' )
{
if ( amount > 0 )
{
cout << " Distance " << amount << " miles is "
<< amount * MILES_PER_KM << " kilometers.";
}
}
return 0;
}

i see u posted in homework help

but id have tried programming for a question like this, bit more than just something quick. althought doubt theyd just do it for u, prob just help u out a bit.

and been forever since i last tried some C++ , was like high school lol. and didnt do too well then... didnt pay attention

why not just do
String unit = "
if(unit == k){
shit;
} else {
if(unit== m){
else;
} else {
if(!unit.Contains(k, m) {
return;
}

my rusty java.. lel

this looks like it would work, but I have to do it the very specific way my professor wants it and C++ compared to your java are different even though im sure they get the same result.

Quit making so many threads. I hate it when i start typing a long response to one thread, but someone already answered it in another thread or via PM. I don't bother anymore.

I didnt mean to make so many but I procrastinated way too long on this because I thought it was easier than it was...add that to the fact that I didnt know there was a programming section or homework help and you get the situation I am in with all the threads i created.

If you do know how to help though please shoot me a PM because I really just need to get kickstarted and I think I can finish this.

What are you confused about?

Code

if(condition) {
do condition true
} else if(condition) {
do condition based on another different trueth
} else if(condition) {
do condition based on another different trueth
} else {
do something if none of the conditions are true
}


It's piss simple stuff.

I know what those mean I was having trouble with getting all my variables and stuff set up because i dont really understand what the difference between char commands and like int or float is.

heres my newer code that has a little more promise than above considering it gives me an output that i kind of want...
