C Programming Fundamentals Assessment

What are the basic data types available in C?

• boolean

• int, float, double, char, void

• string

• array

How do you declare an integer variable in C?

• int myVariable;

• var myVariable;

• integer myVariable;

• float myVariable;

What is the purpose of the 'if' statement in C?

• To execute code conditionally based on a boolean expression.

• To create loops in C.

• To declare variables in C.

• To define a function in C.

Explain the difference between 'while' and 'for' loops in C.

• 'While' loops can only be used with integer values.

• 'For' loops do not require a condition to terminate.

• 'While' loops are faster than 'for' loops in all cases.

• The main difference is that 'while' loops check the condition before each iteration, while 'for' loops are used for a known number of iterations with initialization and increment in one line.

What is a float data type used for in C?

• The float data type is used to represent decimal numbers in C.

• The float data type is used for defining integer values in C.

• The float data type is used to represent characters in C.

• The float data type is used for storing boolean values in C.

How do you create a switch statement in C?

• for(value in variable) { // code; }

• if(variable == value1) { // code; } else if(variable == value2) { // code; }

• switch(variable) { case value1: // code; break; case value2: // code; break; default: // code; }

• while(variable == value1) { // code; }

What is the output of the following code: int x = 5; printf('%d', x++);?

• 6

• 5.0

• 4

• 5

Describe the use of the 'break' statement in control structures.

• The 'break' statement pauses the current loop execution.

• The 'break' statement terminates the current loop or switch case execution.

• The 'break' statement continues to the next iteration of the loop.

• The 'break' statement is used to skip the current iteration in a loop.

What is the purpose of the 'return' statement in a function?

• To exit the function and return a value to the caller.

• To declare a variable within the function.

• To create a loop within the function.

• To define a new function.

What is the role of the 'continue' statement in loops?

• To skip the current iteration and continue with the next iteration of the loop.

• To terminate the loop immediately.

• To pause the loop execution for a specified time.

• To exit the loop and return to the calling function.
