We’ve seen many places where repetition is necessary in a problem.. We’ve been using the for loop for that purpose. For loops are called . definite. loops because we know how many times the loop needs to be executed. Loops in Python.

A loop inside an if statement. Control structures can be nested inside each other to any degree you need . Nested loops. The general principle of nesting loops is that the inner loop must completely finish its execution before the next iteration of the outer loop starts. Describe for loops and their implementation in C . Describe their purpose. Specifically count-controlled loops. Count-controlled loops. We previous looked at executing a block of code a fixed number of times:. Why use loops in C language?. The looping simplifies the complex problems into the easy ones. It enables us to alter the flow of the program so that instead of writing the same code again and again, we can repeat the same code for a finite number of times. For example, if we need to print the first 10 natural numbers then, instead of using the .
