Run your C program in gcc with one line.

gcc one command run

Add aliases in your .(shell)rc:

alias gcb='f(){ gcc "$1" -o "$2"; ./"$2"; unset -f f; }; f'
alias gcr='f(){ gcc "$1"; ./a.out; rm -f a.out; unset -f f; }; f'
The first modifies the name of the binary and executes it. The second compiles, runs, and delete the binary.

Demo gcb:

~$ gcb main.c build 
Hello World
~$ ls
main.c build

Demo gcr:

~$ gcr main.c  
Hello World
~$ ls
main.c
