Trouble understanding the char-type variable

[theMadman]

I've been kind of bridging the gap from PHP/Javascript website design to C++, and found a weirdness about the char variable type.

This is what I don't understand. This program fails to compile:

int main()
{
char testString="t";
cout << testString << "\n";
return 0;
}

with the output:

./stringTest.cpp: In function `int main()`:
./stringTest.cpp:8: error: invalid conversion from `const char*` to `char`

Yet the following program compiles and works as expected:

int main()
{
char testString;
cin >> testString;
cout << testString << "\n";
return 0;
}

int main()
{
char testString='t';
cout << testString << "\n";
return 0;
}

I hope you see now

single-quotes for individual characters, double-quotes for strings?

[Denis]

yes
