Why 'for' loop not working, but 'while' working?

[urbangeek]

hello guys,
the output of the program should be like this:

With how many numbers do you love to work with? 3
Enter no 1: 23.4
Enter no 2: 15.54
Enter no3: 55.48

In ascending order the numbers are:
15.54
23.40
55.48

I've written this program:

#include <stdio.h>
#include <stdlib.h>
int main()
{
    int i,limit,flag;
    double numbers[100],temp;
    char inputstr[50];
    printf("With how many numbers do you love to work with? ");
    fgets(inputstr,49,stdin);
    limit=atoi(inputstr);
    for(i=0;i<limit;i++);
    {
        printf("Enter number %d: ",i+1);
        fflush(stdout);
        fgets(inputstr,49,stdin);
        numbers[i]=atof(inputstr);
    }
    while(1)
    {
        flag=0;
        for(i=0;i<limit-1;i++)
        {
            if(numbers[i]>numbers[i+1])
            {
                temp=numbers[i];
                numbers[i]=numbers[i+1];
                numbers[i+1]=temp;
                flag=1;             //flag=1 if the atleast one number get swapped in the array
            }
        }
        if(flag==0){break;}         //no swapping anymone, i.e. the numbers are in order already
    }                               //outer while loop end
    printf("\nIn Ascending order the numbers are:\n");
    for(i=0;i<limit;i++)
    {
        printf(" %.2lf\n",numbers[i]);
    }
    return 0;
}

The output is like:

With how many numbers do you love to work with? 3
Enter no 4: 23.4

In ascending order the numbers are:
0.00
1.#R
1.#R

I changed the for for loop into while loop in line 11:

while(i<limit)
    {
        printf("Enter number %d: ",i+1);
        fflush(stdout);
        fgets(inputstr,49,stdin);
        numbers[i]=atof(inputstr);
        i++;
    }

Now it's working perfect. But how it is possible? And also how come the program was asking me for "Enter no 4" where i just set the limit to 3 numbers!!?:-/

Thanks in advance

for(i=0;i<limit;i++); <---- semi colon

You have a semicolon after the for loop at line 11, so the for loop just runs line 11 the amount of times required. When the loop finishes, i will now be at the maximum value. Once you take off the semicolon, the code works okay.

Shucks,

Didn't see the above post, where are my glasses?

[urbangeek]

for(i=0;i<limit;i++); <---- semi colon

ah...how did i miss that!!

where are my glasses?

man...i need glasses....
m too bad in debugging..:(
