'c' 10int sort

']['HeBroken · 11-10-2004, 07:16 PM

hey all i did a search for this but didnt come out good, so i need a little bit of help here. Ok i need to create a program that will take in 10 int's and show the highest , lowest , average and sum. How the hell do i do this?. im so in the dark with this. any help will be appreciated thank you in advance...

I'd use an array probably:

Code:

int sort[10];

i tried that. erm what i need to do is take the ten ints, swap them and sort them according to size... im so friken stumped on how to do this..

']['HeBroken · 11-10-2004, 09:18 PM

ok ill make it easier for meself and u guys.. ill show the code..

Code:

#include <stdio.h>
#include <stdlib.h>



#define MAX 10

int iNums(int *);
int iLow(int *);
int iLar(int *);
int iSum(int *);
float fAver(float *);


int main()
{
	int iNums[MAX];
	int *ptr_iNums;
	int iCount = 0;
	int *ptr_iSum;
	int *ptr_iLow;
	int *ptr_iLar;
	float *ptr_fAver;



	for ( iCount = 0; iCount <MAX; iCount++)
	{
		printf("\n GIVE ME NUMBER %d", iCount + 1);
		scanf("%d", &iNums[iCount]);
	}

}

now what im trying to do is take all the numbers it takes in and sort them and show them to the screen. i did a google search but all i got was crap results and very confusing ones. if any help thank you muche....

You can do a very inefficient sort pretty easily. It won't matter that it's inefficient with 10 measly numbers, but you'd want to use a better algorithm with a larger set. The code would be something like this:

Code:

outer loop
  inner loop
    if sort[outer loop] is less than sort[inner loop]
      set temporary int to sort[outer loop], set sort[outer loop] to sort[inner loop], set sort[inner loop] to temporary int

alrighty this is what i got so far.. this is probably so f-ed up its not funny but here it goes..

Code:

#include <stdio.h>
#include <stdlib.h>

/******************************************************************
			
			11/11/04
			10 int's sorted Large, low, aver and sum
********************************************************************/

#define MAX 10

int iNums(int *);
int iLow(int *);
int iLar(int *);
int iSum(int *);
float fAver(float *);

void main()
{
	int iNums[MAX];
	int *ptr_iNums;
	int iCount = 0;
	



	for ( iCount = 0; iCount <MAX; iCount++)
	{
		printf("\n GIVE ME NUMBER %d", iCount + 1);
		scanf("%d", &iNums[iCount]);
	}
	*ptr_iNums = *iNums;



}
// Starting the swaping 
void swap(int *ptr_iNums)
{
	int temp;
	temp = *ptr_iNums;
	*ptr_iNums = *ptr_iNums;
	*ptr_iNums = temp;
}


		void sort *iNums();
		{
		int iswap = iCount;
		while(swap)
	}
		iSwap = 0;
			for (iCount = 0; iCount <MAX; iCount++)
		{
		if(iNums[iCount] <= iNums[iCount])
		{
		swap(*ptr_iNums, *ptr_iNums)
		}
		iswap = 1;
		}

now does that look anything close to what im trying to do?....

this is the errors that i get when i do it...

Code:

c:\P4V2\P4V2.c(53): error C2059: syntax error : ')'
c:\P4V2\P4V2.c(47): error C2143: syntax error : missing '{' before '*'
c:\P4V2\P4V2.c(47): error C2040: 'iNums' : 'int *()' differs in levels of indirection from 'int (int *)'
c:\P4V2\P4V2.c(48): error C2449: found '{' at file scope (missing function header?)
c:\P4V2\P4V2.c(51): error C2059: syntax error : '}'
c:\P4V2\P4V2.c(53): error C2059: syntax error : 'for'
c:\P4V2\P4V2.c(53): error C2143: syntax error : missing '{' before '<'
c:\P4V2\P4V2.c(53): error C2059: syntax error : '<'

c:\P4V2\P4V2.c(53): error C2059: syntax error : '++'

thank you for takin your time to help me. im such a newb when it comes to this.......

Well, those syntax errors should be easy enough to fix. One problem you're having is that you're passing 2 values to swap(), but swap() is only accepting one. Your indentation is atrocious. Cleaning that up so you can easily follow blocks of code usually helps in the debugging process immensely.

']['HeBroken · 11-10-2004, 11:36 PM

all im getting now is

Code:

c:\P4V2\P4V2.c(59): error C2059: syntax error : '}'
c:\P4V2\P4V2.c(46): error C2449: found '{' at file scope (missing function header?)

and they are pointing to these right here....

Code:

void sort (int *ptr_iNums);
		{ <------ THIS ONE
		int iswap = iCount;
		while(swap)
		
		iswap = 1;
		
			for ( iCount = 0; iCount <MAX; iCount++ )
		if(iNums[iCount] <= iNums[iCount])
		{
		swap( *ptr_iNums, *ptr_iNums );
		
		iswap = 2;
		}
		} <--------- & this one

They are in the right places right?

1.Why sort the file? just parse it and compare the values with the lowest / largest
2.DO NOT use global variables unless it's really necessery.

Code:

#include <stdio.h>
#include <stdlib.h>
#define MAX 10

float my_func(int *Nums,int *Sum,int *Low,int *Lar)
{
	int count;
	*Sum =*Low = *Lar = Nums[0];                                   /* initialize Low/Lar/Sum*/  
	for (count = 1; count < MAX;count++)
	{
		if (*Low > Nums[count]) *Low = Nums[count];  /*if Nums[count] is lower than current Low*/
		if (*Lar < Nums[count]) *Lar = Nums[count];     /*if Nums[count] is larger than current Lar*/
		*Sum += Nums[count];                                          /*add Nums[count] to sum */
	}
	return *Sum/10.0;                               /*10.0 for casting the result to float, returning the Average*/
}

int main()
{
	int Nums[MAX];
	int Count = 0;
	int Sum,Low,Lar;
	float Aver;
	printf("\n\t* c 10int *\n\n");
	for ( Count = 0; Count < MAX; Count++)
	{
		printf("GIVE ME NUMBER %d :", Count+1);
		if(!scanf("%d", &Nums[Count]))
		{
		fprintf(stderr,"Wrong Input\n");
		exit(0);
		}	
	}
	Aver = my_func(Nums,&Sum,&Low,&Lar);
	printf("\n\t*RESULTS*\n\n");
	printf("Lowest:\t\t%d\nLargest:\t%d\nSum:\t\t%d\nAver:\t\t%.1f\n",Low,Lar,Sum,Aver);
	return 0;
}

Whooo hooo you are awsome.... that was even simpler than the first.. thank you muchies.......
