C Programming Concepts Challenge

What is the correct syntax to define a function in C?

• return_type function_name(parameter_type parameter_name) { // function body }

• return_type { function_name(parameter_type parameter_name) }

• function_name { return_type parameter_type parameter_name }

• function_name(parameter_type) return_type { // function body }

How do you declare an array of integers in C?

• int arr(10);

• int array[10];

• array int arr[10];

• int arr[10];

What will be the output of the following loop: for(int i=0; i<5; i++) printf("%d ", i);?

• 1 2 3 4 5

• 0 1 2 3 4

• 0 1 2 3

• -1 0 1 2 3

What is the purpose of the 'break' statement in a loop?

• To exit a loop prematurely.

• To restart the loop from the beginning.

• To skip the current iteration of the loop.

• To pause the loop temporarily.

How do you access the third element of an array named 'arr'?

• arr(2)

• arr{2}

• arr[3]

• arr[2]

What will the following code output: if(5 > 3) printf("True"); else printf("False");?

• True

• Maybe

• False

• Definitely not

What is the result of the following pointer arithmetic: int *p; p = arr; p++;?

• p is uninitialized and cannot be used.

• p now points to the second element of the array (arr[1]).

• p now points to the first element of the array (arr[0]).

• p now points to the third element of the array (arr[2]).

How do you declare a function that takes an array as a parameter?

• function myFunction(array) { // code here }

• myFunction(arr) => { // code here }

• function myFunction(arr: Array) { // code here }

• function myFunction(arr) { // code here }

What is the output of the following code snippet: int a = 10; if(a == 10) printf("Equal"); else printf("Not Equal");?

• Not Equal

• Equal to 15

• Equal to 5

• Equal

What is the difference between a while loop and a do-while loop?

• A while loop executes at least once before checking the condition; a do-while loop checks the condition first.

• A while loop can only be used with integer values; a do-while loop can use any data type.

• A while loop checks the condition before execution; a do-while loop executes at least once before checking the condition.

• A while loop is used for infinite loops; a do-while loop is used for conditional loops.
