    selfstudy: Remove all smallest integers

    #include <stdio.h>
    #define MAX_ARRAY_SIZE 100
    int RemoveAllSmallest(int A[],int n) 
    	int i;
    	int id_smallest=0;
    	int min_value=A[0];
    		for (i=1;i<n;i++)
    			if (A[i]<min_value)
    		for (i=id_smallest;i<n-1;i++)
    void main()
    {	int i;
    	int A[MAX_ARRAY_SIZE];
    	int n;
    	//Ask and read the number of integers.
    	printf("How many integers totally? (1-%d)",MAX_ARRAY_SIZE);
    	printf("\nInput the integers.\n");
    	printf("(Each integers should be in the range 0-99. ");
    	printf("Seperate them with spaces.)\n");
    	//Read all integers 
    	for (i=0;i<n;i++)
    	//Remove all smallest numbers
    	//Display result
    	printf("\nAfter removing all smallest number(s):\r\n");
    	for (i=0;i<n;i++)
    		printf("%d ",A[i]);

    I have tried the above, but it can not remove all the samllest integer, but only one. Can anyone help me to approch it?

    Layout ten M&Ms in front of you in a row. Start removing all the yellow ones and sliding the others over to fill in the empty spaces. Each time you remove another yellow one, notice how the sliding you are doing changes. Do the same thing with your array.

    Also, don't forget to return a value from your function. What value you return will also help you figure out when to stop the deletion loop.

    First: code tags are your friend.

    Second: This is the C++ forum; your program is C. Either you should convert it to C++ (which in fact would make this far, far easier to solve -- using a std::vector in place of the array makes the logic for removal trivial) or ask the mods to move the post to the correct forum.
    You ever try a pink golf ball, Wally? Why, the wind shear on a pink ball alone can take the head clean off a 90 pound midget at 300 yards.

    void main()
    I thought many compilers would flag this as an error nowdays. Void main has long since gone.
    I use
    int main ( void )
    . I think void main is non standard, but i could be wrong.
    Perhaps C compilers like Miriacle C still accept it, but many standard C++ compilers wouid give at least a warning

    Miracle C isn't a C compiler.
    It's a student assignment pretending to be a compiler, but since it's $$$ nagware, and there are many free (and fully featured) compilers available, it makes for a very poor choice.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
