bash alias - running two commands

Question

How do I make an alias in my .bashrc such that I can run two commands with arguments?

For example, compile source and run.

gcc-run -lm example.c

would run

gcc -lm example.c
./a.out

The closest I found was this question but it doens't have any arguments.

If you want to pass an argument, you can't use an alias. You need to use a shell function. It sounds like you want something similar to

gcc-run () {
    gcc "$@"
    ./a.out
}

Another small related question. How would I then pick out individual arguments to use in an if-else statement?

the shell functions are simuliar as "normal" shell program, you can use $1 $2... for individual arguments.

You might actually want to make sure that compilation was successful. gcc-run () { gcc "$@" && ./a.out; }
