How can I put back a character that I've read when I detect it's the start of a new row?
- by gcc
char nm; int i=0;
double thelow, theupp; double numbers[200];
for(i=0;i<4;++i)
{ { char nm; double thelow,theupp; /*after erased ,created again*/
scanf("%c %lf %lf", &nm, &thelow, &theupp);
for (k = 0; ; ++k) ;
{ scanf("%lf",numbers[k]);
if(numbers[k]=='\n') break;
}
/*calling function and sending data(nm,..) to it*/
} /*after } is seen (nm ..) is erased*/
;
}
I want say compiler : hey my dear code read only i-th row,dont touch characters at placed in next line. because characters at placed in next line is token after i increased by 1 and nm ,thelow,theupp is being zero or erased after then again created.
how can I do ?
