Shell script not running through all files of certain extensions - bash

Question

I wrote a shell script that searches the directory that it is in for files that match any suffixes in the env var SUFFIXES.
#!/bin/bash
SUFFIXES=$(SUFFIXES:-'.c .cpp .cc'}
CC=${CC:-gcc}
CFLAGS=${CFLAGS:-"-Wall -Werror"}
VERBOSE=${VERBOSE:-1}
for i in *$SUFFIXES
do
$CC $CLAGS -o ${i%$SUFFIXES} $i 2> /dev/null
if [ $VERBOSE == 1 ]
then
echo "$CC $CLAGS -o ${i%$SUFFIXES} $i"
fi
done
Say I have a directory with hello.c, hey.c, howdy.cc, and hallo.cpp. Whenever the script is ran without changing the environment variables in the terminal, I get the following output:
gcc -Wall -Werror -o hello.c hello.c
gcc -Wall -Werror -o hey.c hey.c
gcc -Wall -Werror -o .cc .cc
gcc -Wall -Werror -o .cpp .cpp
The output that I am trying to get is:
gcc -Wall -Werror -o hello hello.c
gcc -Wall -Werror -o hey hey.c
gcc -Wall -Werror -o howdy howdy.cc
gcc -Wall -Werror -o hallo hallo.cpp
How would I go about fixing this?

Except for a few typos in your code that probably occurred here, you have some mistake in your loop
i in *$SUFFIXES means that *.c .cpp .cc, so it won't work on file.cpp or file .cc
${i%$SUFFIXES} try to cut all suffixes that you defined, from end of file name, while you have one of them in each file name
maybe an inner loop will helpful
for i in $SUFFIXES
do
for j in *$i
do
$CC $CFLAGS -o ${j%$i} $j 2> /dev/null
if [ $VERBOSE == 1 ]
then
echo "$CC $CFLAGS -o ${j%$i} $j"
fi
done
done
