Does anyone know C? I need help!

Hey I am taking an intro to C class and I am having trouble with my loops. If anyone could help me let me know!

bool joshboxislost;
int headaches;

while(joshboxislost)
{
headaches++;
}

[quoteb363f34855="bballp6699"]bool joshboxislost;
int headaches;

while(joshboxislost)
{
headaches++;
}[/quoteb363f34855]

yeah that...

;) I know C++...

Bit rusty.

Might be able to help though...

Post what you're having difficulty with.

This goes into an endless loop and does not run scanf at the beginning of each iteration of the loop

int main (void)
{
/li local definitions li/

float addinput;
float inputammount;
float highest;
float lowest;
float current;

/li statements li/

printf("Input any ammount of numbers\n\n");

while (current >= 0);
{
scanf("%f", current);

if (current > highest);
highest = current;

if (current < lowest);
lowest = current;

addinput = addinput + 1;

inputammount = inputammount + current;

}

Sure C is the letter after B and before D. Hope that helps. Next week we'll try finish the entire alphabet.

omg thanks so much thats what what was wrong! ;-)

current has no value. You're starting the loop before you have a value for it. Try moving the scanf statement outside of the loop and see what happens.

I need scanf inside the loop though because i need it to scan for an undetermined ammount of values

Ok, so each time they enter a number, it's added to whatever the last total was?

I'm having trouble understanding what you're trying to do, but the loop you're using won't work for what you're saying you need to do. You might want to try a do while loop, which might work out better for you.

My C knowledge is a little rusty, but I used to be a Lab TA for an intro to C course at Purdue, so I know a bit about it. =o)

heres my current thanks to bballp he helped me get it working


#include <stdio.h>

int main (void)
{

int addinput = 0;
int inputamount = 0;
int highest = 0;
int lowest = 0;
int current = 0;
int avg;

printf("Input any amount of positive numbers - Enter a negative number to stop.\n\n");

scanf("%d", &current);
lowest = current;

while(current >= 0)
{

if (current > highest)
highest = current;

if (current < lowest)
lowest = current;

addinput = addinput + 1;

inputamount = inputamount + current;

scanf("%d", &current);

}

avg = inputamount/addinput;

printf("The highest number in the list was \n");
printf("%i\n", highest);
printf("The lowest number in the list was \n");
printf("%i\n", lowest);
printf("The average of the list was \n");
printf("%i\n\n", avg);

return 0;
}

Glad you got it working. I wasn't sure what you were trying to do.

I was still right about needing to scan outside of the loop, I just wasn't right about keeping the other inside. =o)

ask your teacher

lol

hehe, once you go Perl, you can't go back to C anymore (unless your boss wants you to)

i never learned C.. only C++ and i forgot most of C++ because i only coded a few programs.

Anyone else find it ironic that THIS code wont work as intended for the same reason that the OPs code wasn't working? (var not initialized)

all i know if f-ing java so there...and yeah that's nice Admin
