Iteration and loops are fundamental programming techniques used to repeat a set of instructions a specific number of times. They allow you to perform a specific task or operation on a set of data.
Iteration is a sequence of instructions that execute a block of code repeatedly, executing the same set of operations until the loop condition is met. The loop condition can be based on various conditions, such as the value of a variable, the completion of a specific operation, or reaching a certain point in a program.
Loops are a structured way of iterating through a set of data. They provide more control over the order of execution compared to iteration. There are two main types of loops: for loops and while loops.
For loops execute a block of code a specified number of times. The number of iterations is defined explicitly within the loop condition. For example, the following code uses a for loop to print the numbers from 1 to 10:
for (int i = 1; i <= 10; i++) {
printf("%d ", i);
}
While loops continue to execute a block of code until a specified condition is met. The loop condition is checked before each iteration, and if it is true, the loop continues to execute. Once the condition is false, the loop terminates.
For example, the following code uses a while loop to print the numbers from 1 to 5:
int i = 1;
while (i <= 5) {
printf("%d ", i);
i++;
}
By understanding iteration and loops, you can write more efficient and elegant code that can solve various problems
