How does the for loop function in C?
a) Repeats code a specific number of times
b) Executes code only once
c) Checks a condition after executing
d) Declares a variable
Answer:
a) Repeats code a specific number of times
Explanation:
The for loop in C is designed to repeat a block of code a specific number of times. It is commonly used when the number of iterations is known before entering the loop. The for loop has three main parts: initialization, condition, and increment/decrement. These are used to control the loop’s execution.
For example, a for loop can be used to iterate through elements in an array or to perform a set of operations a predetermined number of times. Mastery of the for loop is fundamental to efficient programming in C.
