Thread: A few problems getting data from an array

Hey guys, having a bit of trouble with more of this array stuff. This is my code so far:

Code:

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

int main(void)

{
int data[50];
int i, n, start, stop;

printf("How many integers should I read (1--50)? ");
scanf("%d", &n);

if(n > 50)
{
	printf("That value is too large.\n");
		exit(1); 
}

printf("\nEnter your values, one per line.\n");

for(i = 0; i < n; i++)
	scanf("%d", &data[i]);

printf("\nYou entered\n");
	for(i = 0; i < n; i++)
	printf("%d\n", data[i]);

	printf("Enter a Starting Value: ");
	scanf("%d", &start);

	printf("Enter a Stopping Value: ");
	scanf("%d", &stop);

	
}

There are a few things I gotta get out of this. I have to print the values from the array that are greater than or equal to the starting value AND less than or equal to the stopping value. I then have to count the number of values between the starting and stopping values and how many of them are even and how many are odd. I tried using some IF statements, but it wasnt working out.

Try with the following code,

Code:

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

int main(void)

{
int data[50];
int i, n, start, stop;
int count=0,even=0,odd=0;
printf("How many integers should I read (1--50)? ");
scanf("%d", &n);

if(n > 50)
{
        printf("That value is too large.\n");
                exit(1);
}

printf("\nEnter your values, one per line.\n");

for(i = 0; i < n; i++)
        scanf("%d", &data[i]);

printf("\nYou entered\n");
        for(i = 0; i < n; i++)
        printf("%d\n", data[i]);

        printf("Enter a Starting Value: ");
        scanf("%d", &start);

        printf("Enter a Stopping Value: ");
        scanf("%d", &stop);

        printf("Elements are :");
for(i=0;i<n;i++)
{
        if(data[i]>=start&&data[i]<=stop)
        {
                printf("%d ",data[i]);
                count++;
                if((data[i]%2)==0)
                        even++;
                else
                        odd++;
        }

}

printf("\n");
printf("Count : %d \n",count );
printf("Odd : %d \n", odd );
printf("Even : %d \n",even );
}

Thanks a lot man. Got an error about the count, even, and odd not being declared or something, but I figured that out.

Question, the data[i] is basically the directory for everything that was inputted into the array? I thought you would have to do a separate statement for each variable in the array.

Code:

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

int main(void)

{
int data[50];
int i, n, start, stop;

printf("How many integers should I read (1--50)? ");
scanf("%d", &n);

if(n > 50)
{
        printf("That value is too large.\n");
                exit(1);
}

printf("\nEnter your values, one per line.\n");

for(i = 0; i < n; i++)
scanf("%d", &data[i]);

int j ;
int temp;
int stat,stat1;

for(j=0;j<n;j++)
{
for(i=j;i<n-1;i++)
if(data[j]>data[i+1])
{
temp=data[j];
data[j]=data[i+1];
data[i+1]=temp;
}
}

 printf("\nYou entered\n");
for(i = 0; i < n; i++)
printf("%d\n", data[i]);

        printf("Enter a Starting Value: ");
        scanf("%d", &start);

  printf("Enter a Stopping  Value: ");
        scanf("%d", &stop);

 for(i=0;i<n;i++)
{
        if(data[i] == start)
        {
           stat=i;
        }
        if(data[i] == stop)
        {
                stat1=i;
        }
}

int even=0;
int odd=0;
int count=0;
 printf("The  elements between %d and %d are\n",start,stop);
for(i=stat;i<=stat1;i++)
{
         count++;
        printf("%d ", data[i]);
        if((data[i]%2)==0)
               even++;
        else
                odd++;
}
printf("\nThe odd is :%d\n",odd);
printf("The even is :%d\n",even);
printf("The count is:%d\n",count);
}

Note: This code will take the start and stop number as a last number only, if you give the duplicate element for an array values.

sorry ! I can not understand your question.
