string fullname;inta = fullname.length(); I see that at this point in the code, the string is empty. Of size zero. Soawill always be zero. So you might as well just write inta = 0; Did you mean for a to always b
std::string to_string( int value ); Defined in header <string>. Converts a numeric value to std::string. 1) Converts a signed decimal integer to a string with the same content as what std::sprintf(buf, “%d”, value) would produce for sufficiently large buf. An example C++ program...
I can do a loop to add a string to a new string/int and break whenever I see a hyphen. I think this is what was intended. I can do a sort of combination like my current code. I can stoi the month value really easy and remove the year value. If I could store that year to an...
cin, input); while(input != "q"){ stree.insert(stringto_int(input)); stree.print(); getline(cin, input); } } else if(input == "2"){ cout << endl; cout << "Enter integer keys to delete. Enter \"q<Enter>\" to quit." << endl; cout << endl; getlinecin, input); ...

what we still have to know is: When does an error occur? It does occur if you expect an integer, (like in your case) but the first chars in your string are no numbers, but some alphabetic chars. In other words, if the Stream cant extract what you wish for, because we cant match...
Edit & run on cpp.sh '12345' => converted to integer 12345 '12345xyz' => converted to integer 12345 the first 5 characters were converted 'xyz12345' => no conversion could be performed '123456789012345' => converted value would be out of the range of an int ...
mystring[1] = 0xBC; mystring[2] = 0x7D; mystring[3] = 0xEA;myint[0] = mystring[3]; myint[1] = mystring[2]; myint[2] = mystring[1]; myint[3] = mystring[0];mycastint = (int*)myint;This will convert your string into an integer correctly. The reason why you must do ...
#include <iostream> #include <string> using namespace std; int main() { int x = 70; int *ptr; ptr = &x; cout << *ptr << endl; } Edit & run on cpp.sh ok so int x = 70; and i made a pointer *ptr, then i assigned the memory address of x to ptr then de refernced ...
After days of attempts, I am able to grasp that UInt8Array in the index.cpp file, but not able to convert it to c++ datatypes such as std::array or std::vector. For Integer type or String type, I can cast it to using ToNumber() or ToString(). But for direct conversion of ...
