I want to read numbers(integer type) separated by spaces using scanf() function. I have read the following:
It doesn't help me much.
How can I read numbers with space as delimiter. For e.g. I have following numbers as input 2 5 7 4 3 8 18 now I want to store these in different variables. Please help.

There are 2 methods to take input from the user which are separated by space which are as follows: Using BufferedReader Class and then splitting and parsing each value. Using nextInt( ) method of Scanner class.
So we use “%[^\n]s” instead of “%s”. So to get a line of input with space we can go with scanf(“%[^\n]s”,str);
Adding a whitespace character in a scanf() function causes it to read elements and ignore all the whitespaces as much as it can and search for a non-whitespace character to proceed. scanf("%d "); scanf(" %d"); scanf("%d\n"); This is different from scanf("%d"); function.
The scanf() function can read input from keyboard and stores them according to the given format specifier. It reads the input till encountering a whitespace, newline or EOF.
I think by default values read by scanf with space/enter. Well you can provide space between '%d' if you are printing integers. Also same for other cases.
scanf("%d %d %d", &var1, &var2, &var3); Similarly if you want to read comma separated values use :
scanf("%d,%d,%d", &var1, &var2, &var3); scanf uses any whitespace as a delimiter, so if you just say scanf("%d", &var) it will skip any whitespace and then read an integer (digits up to the next non-digit) and nothing more.
Note that whitespace is any whitespace -- spaces, tabs, newlines, or carriage returns. Any of those are whitespace and any one or more of them will serve to delimit successive integers.
