Write C Programs for the Following Problems:
Follow these steps to compile and execute a C program on a Linux operating system. By default, Linux provides a C compiler.
-> Open a text editor from the Applications menu.
-> Write your C program according to the given problem.
-> Save the program file with a .c extension, for example, abx.c .
-> Open the Terminal from the Applications menu.
-> Type the following command in the terminal to compile the program:
gcc abx.c -lm
-> If the compilation generates any error messages, correct the errors in the program and compile it again.
-> If the compilation is successful, a binary executable file named a.out will be generated in the current directory.
-> Execute the binary file by typing the following command in the terminal:
./a.out
-> After execution, the successful output of the program will be displayed in the terminal.
