String Problem
I have a bit of a problem with this:
The problem is: no matter what I type in, it prints out the else statement.Code:#include <iostream.h> #include <string.h> int main() { cout << "\nEnter a number: "; char name[50]; cin.getline(name, 50, '\n'); strcmp(name, "Dean"); if (name == "Dean") cout << "\nThat's my name too!"; else cout << "\nThat's a nice name!"; return 0; }
You can't compare c-strings using ==
You need to put your call to strcmp inside the if statement, and check if it returns 0;
if (strcmp(name, "Dean") == 0)
OR you could use C++ strings, they'll save you a lot of trouble
Code:#include <iostream> #include <string> //... std::string name; getline(std::cin, name); if (name == "Dean) // ... else //...
Ok im pretty sure that strcmp returns either 0(true) or 1(false) so try this insteadThe problem is: no matter what I type in, it prints out the else statement.
and wouldnt it be enter a name, not enter a number =\.Code:if (strcmp(name, "Dean") == 0) ...

They are right, you should use strcmp(), but I was wondering why did you do this:
I cann't get why.Code:strcmp(name, "Dean"); if (name == "Dean")
none...
using strcmp...
Code:#include <iostream.h> #include <string.h> int main() { cout << "\nEnter a number: "; char name[50]; cin.getline(name, 50, '\n'); if(!strcmp(name, "Dean") cout << "\nThat's my name too!"; else cout << "\nThat's a nice name!"; return 0; }
I am against the teaching of evolution in schools. I am also against widespread
literacy and the refrigeration of food.
