I am learning to program C++ and I am learning about loops. Why won't this program compile? Here is the error message I am getting:
Quote/usr/lib/gcc/x86_64-linux-gnu/4.9/../../../x86_64-linux-gnu/crt1.o: In function `_start':
(.text+0x20): undefined reference to `main'
collect2: error: ld returned 1 exit status
If anyone here is fluent in C++ I would appreciate help.
I thought I identified the problem, I saved it with .cpp rather than .cc. I tried to compile it again and got,
Quote/usr/lib/gcc/x86_64-redhat-linux/5.3.1/../../../../lib64/crt1.o: In function `_start':
(.text+0x20): undefined reference to `main'
collect2: error: ld returned 1 exit status
Every C++ program needs a main() function:
int main() {
cout << "Hello, world!\n";
return 0;
}
I always liked to use a working example, when I was learning. Then make lateral modifications to get what my goal was. That way, all the bits are there for the particular language and compiler and run-time environment. As soon as it broke, then the last change I made is where the error is.
My first C language experience was negative, because the compiler sucked. In theory it was supposed to ignore white space, but it didn't. So I removed all the white space, then put it all back in. Probably couldn't tell a single space from a one-space tab ;-)

Thank you very much, this worked.
