How is a C program executed?
a) Write, compile, and run
b) Write and run
c) Compile and run
d) Write, run, and compile
Answer:
a) Write, compile, and run
Explanation:
A typical C program goes through three main stages: writing the source code, compiling the code into an executable file, and running the program. The process starts with writing the program in a text editor, followed by using a C compiler to translate the source code into machine code. Finally, the compiled code is executed to perform the desired operations defined in the program.
This sequence is crucial because the compiler checks for syntax errors and other issues during the compilation stage, ensuring that the program runs correctly. If the program contains errors, the compilation will fail, and the errors must be corrected before the program can be executed.
