The use of a backslash seems to date back to the days when punch cards were used:

Making the number of spaces at the end of a line be
signifigant means you can't represent your programs on punch cards, or

If you don't use punch cards you could use something like this:
#include <stdio.h>
int main() {
printf("hello"
", dear");
return 0;
}
