Hi I need to have an array in my program that is defined by the user. I just need the user to enter the size of the array and then enter the integer values that they want to store in the array.
I know how to declare the array myself, and Ive looked around and I cant find a straightforward solution to my problem. Any help/suggestions will be greatly appreciated.
Thankyou

Jump to Postscanf is the input function in C. You'll want to ask the user for the size of the array, and then have a loop that reads their numbers. Do you know how to do a loop?
Jump to Postif you are not new to C language then you can use malloc or calloc function to create your Arrays..
Jump to Post…# include <stdio.h> # define MAX 100 int main(void) { int array[MAX],i,n; printf("\n Enter Array size (1 - %d):",MAX); scanf("%d", &n); for(i = 0; i < n; i++) { printf("\n Enter %d value :",i+1); scanf("%d", &array[i]); } // whatever else you want to do....... return 1; }

I am new to C language and I have no idea what those are functions? Will it be easier to use?

it's easier to use but cause you are new then you should use predefined arrays.

ok
# define MAX 100
int main(void)
{
int array[MAX],n;
// scan array size from user but it must not be greater than MAX
scanf("%d",&n);
// now run your loop from 0 to less than n and scan array values
return 1;
}

Thanks for the quick reply...What loop would you suggest? A for loop? Im not sure how to use the loop to scan the numbers?
Also what does Return 1 do?
Thanks again

# include <stdio.h>
# define MAX 100
int main(void)
{
int array[MAX],i,n;
printf("\n Enter Array size (1 - %d):",MAX);
scanf("%d", &n);
for(i = 0; i < n; i++)
{
printf("\n Enter %d value :",i+1);
scanf("%d", &array[i]);
}
// whatever else you want to do.......
return 1;
}main function returns a integer vaule.. that is why return 1 is used.
