But on codeforces I am getting two weird outputs.In one O/P I am getting just blank spaces while in other O/P I am getting correct output but with no line break; (published)
Since you are using char arrays as strings, you need to make sure that these strings end with a '\0' byte. Or better use c++ string class instead, it is usually less error prone.
By using String class and getline the whole input of the test case is not accepted,i.e,Out of the 9 lines of sequences the code is not reading the last line..Now I am confused.I have also tried by cin, char array including null character at the end but I am not getting expected output. Here I am attaching the link of the same. https://codeforces.com/contest/1335/submission/86218770
Please tell me where I am doing wrong!!
string s1;This creates a string object of length 0. If you want a specific length then just put arguments to the constructor:string s1(10, ' ');creates a string of ten blanks.Ohk!!
THen formally if I say like by declaring a string like this and taking input of length upto 1000 characters many of my previous codes were accepted . Can you explain the logic which poses problem here.Like to the point I want to get to know why by not declaring the string size poses a problem. Like in many cases it is possible that string size is not known to us beforehand. Then what to do in those situations.??
string s; cin>>s;works fine, no problem.string s; s[1]='a';makes problems, because it is an access to undefined memory, an array out of bounds access.This is basic c++ knowledge. Try some of these tutorials.
Ohk Thanks a lot gentleman!!
Dont mix cin/cout with scanf/printf if you use this
ios_base::sync_with_stdio(0)and increase the size of the char arrays by 1 to accomodate the\0.
