• The 'while' loop checks the condition before executing the code inside the loop, while the 'do-while' loop executes the code inside the loop at least once before checking the condition.

• The 'while' loop and 'do-while' loop both check the condition before executing the code inside the loop

• The 'while' loop executes the code inside the loop at least once before checking the condition, while the 'do-while' loop checks the condition before executing the code inside the loop

• The 'while' loop and 'do-while' loop both execute the code inside the loop at least once before checking the condition

What is the use of 'typedef' keyword in C?

Explain the difference between 'local' and 'global' variables in C.

• Local variables are declared inside a function and can only be accessed within that function, while global variables are declared outside of any function and can be accessed by any function in the program.

• Local variables are declared outside of any function and can be accessed by any function in the program, while global variables are declared inside a function and can only be accessed within that function.

• Local variables are declared inside a function and can only be accessed within that function, while global variables are declared inside a function and can be accessed by any function in the program.

• Local variables are declared outside of any function and can be accessed by any function in the program, while global variables are declared outside of any function and can only be accessed within that function.
