git clone https://github.com/IldhanSec/simple-calculator-c.git
cd simple-calculatorUsing GCC (Linux/macOS/Windows with MinGW):
gcc calcu.c -o calcu -lm
-lmis required to link the math library.
./calcuIf you don't have a compiler like GCC, it is recommended to install it,
otherwise the program will not run because it requires a compiler,
if you are using Windows it is recommended to install minGw because it is one of the C language compilers.
- Launch the program from your terminal.
- Select an operation from the menu.
- Enter the numbers when prompted.
- Instantly get the result.
