Thread: string & if statement

This is a basic question so here goes. I'm trying to perform a logic operation on a string (an if statement on a persons name). I've tried with quotation marks "if (name == "Joe")" and with apostrophes "if (name == 'Joe')" but neither seems to work. Name is declared as "char name[25]." The statement with quotation marks it thinks even if I type the name right it is false. With apostrophes I get a "warning: multi-character character constant" error. Since I don't know anything I don't know where to start looking for answers. I've tried getting the string with "cin" and "cin.getline" but both give the same results. Also is there a way to make this statement not caps sensative, so "joe", "Joe", or "JOe" all end up being true in the statement?

look up strcmp().

please excuse my syntax on toupper, i havent used it in a while and i think i may have messed up. im sure someone will correct if i am wrong


and btw, wut did i do wrong with the quote tag?

you did mess it up, it's supposed to be used in a for loop since it takes one character, and this is a char array.

i.e.

Code:

int i;
for(i=0; i < SIZE; i++) {
  name[i] = tolower(name[i]);
  //you could also use toupper
  // name[i] = toupper(name[i]);
}

tolower() and toupper() are in cctype.

I think there may be one that does the whole string, not sure.

Using a string object might be helpful...

Code:

#include <iostream>
#include <string>

using namespace std;

int main() {

	string name;

	getline(cin, name);

	if(name == "Joe") 
		cout <<"My name is Joe too! (ok, not really)" <<endl;
}
