    terminate a bubble sort

    My bubble sort finishes before the loop finishes, so I get some unless printout. Is there a way I terminate my bubble sort early if no more swaps is being made with code without using bool?

    void sortlist(int nums[],int size)
    		for(int index = 0 ; index < size-1; index++)		
    			if (nums[index] > nums[index+1])
    			   int temp = nums[index+1];   
    	    nums[index+1] = nums[index];               
    	      nums[index] = temp;

    Don't call printlist() inside sortlist() perhaps?

    Besides, I thought a bubble sort had two nested loops, and you only have one.
    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.
