Definition : Lines terminated by a backslash(\) are specified together with the next line very early in the process of translation.
Meaning and use : If we use a backslash (\) at the end of a comment line then the ending backslash makes the next line also a comment for the Compiler.
EX :
int main () {
//line splicing \
printf("Hello\n") ;
printf ("welcome") ;
return 0;
}
Output : welcome
Reason : the line printf ("welcome") ; treated as a comment by Compiler because at line the commented line is ending with a \.
