    This is supposed to sum up numbers entered by the user but, for some reason it seems to only add every second number!!!
    # include <stdio.h>

int main(void){
    int sum = 0;
    int add = 0;

    while (scanf("%d", &add) == 1){
	scanf("%d", &add);
	sum = sum + add;
	printf("Sum = %d\n", sum);}

    printf("\nThe sum of those numbers is %d.\n", sum);
    return 0;
}

    looks like you're doing scanf twice, but only adding once. try it without the second scanf statement.

    You're using scanf twice in each pass through loop.

    Remember, anytime you call a function, you are running it AND testing its result.
