How to install gcc 7.4 on noobs 3.2.1 version..?

Why doesn't the default gcc work for you? Later versions are usually a superset of older junk. — Dougie, Oct 10, 2019 at 9:08
You can't install anything (except an OS) on NOOBS, because it isn't an OS. — Milliways, Oct 10, 2019 at 12:05
Raspberry Pi Desktop - a operating system for PC and Mac has NOTHING to do with the Pi or NOOBS — Milliways, Oct 10, 2019 at 12:06

I'm assuming you have buster installed. As mentioned by @Dougie, there is really no point in using an older version of gcc. However:

Out of the box repos have 7.3:

pi@raspberrypi:~ $ apt-cache madison gcc-7
     gcc-7 |   7.3.0-19 | http://raspbian.raspberrypi.org/raspbian buster/main armhf Packages

You can install it with sudo apt-get install gcc-7
