c++ calling main() function
i just finished a project for a c++ class that i wrote at home on my computer, compiled with gcc. when i brought the code into school it would not compile, it would complain that cannot call main() function. at school we use ancient borland c++ from 1995. anyway my program has 20 different functions, and each one hasa menu to start the program over, some with switch structure, and others with else if, everyone calls the main function when it is started over, so my question is, which is right? in c++ should you be able to call the main function from other functions? or is this a lax in conformity with gcc?
---
i simply created a new function identical to main() and called that when i need to start over.

LEARN ABOUT DEBIAN
builder-cc
BUILDER-CC(1) Debian GNU/Linux BUILDER-CC(1)
NAME
builder-cc - gcc wrapper to facilitate pentium-optimizations
SYNOPSIS
export DEBIAN_BUILDARCH=architecture
export DEBIAN_BUILDGCCVER=gcc-version
gcc ...
DESCRIPTION
The builder-cc wrapper is normally used by calling gcc as usual. If the environment variable DEBIAN_BUILDARCH is not set, builder-cc does
nothing, and the real gcc is invoked with the specified arguments.
When the DEBIAN_BUILDARCH environment variable is set, builder-cc invokes gcc with the specified arguments, plus -mcpu=DEBIAN_BUILDARCH
-march=DEBIAN_BUILDARCH This has the effect of telling gcc to use architecture-specific optimizations without changing the command line.
This is particularly useful for package builds.
If DEBIAN_BUILDGCCVER is not set, builder-cc calls gcc.real. If DEBIAN_BUILDGCCVER is set, builder-cc calls gcc-DEBIAN_BUILDGCCVER
instead.
ENVIRONMENT
DEBIAN_BUILDARCH
If set, the architecture to compile for. Useful values are pentium or pentiumpro.
DEBIAN_BUILDGCCVER
If set, the version of gcc to be invoked. Useful values are 3.0 or 2.95.
NOTES
The real gcc is renamed gcc.real, and a diversion is registered with dpkg-divert(1). Thus builder-cc's idea of the default gcc is dictated
by whatever package installed /usr/bin/gcc.
