Following is the inshort inrodustion of loops theroticaly.
- C++ programming language provides the following type of loops to handle looping requirements.
| Sr.No | Loop Type & Description |
|---|---|
| 1 | while loop
Repeats a statement or group of statements while a given condition is true. It tests the condition before executing the loop body.
|
| 2 | for loop
Execute a sequence of statements multiple times and abbreviates the code that manages the loop variable.
|
| 3 | do...while loop
Like a ‘while’ statement, except that it tests the condition at the end of the loop body.
|
| 4 | nested loops
You can use one or more loop inside any another ‘while’, ‘for’ or ‘do..while’ loop
|
There may be a situation, when you need to execute a block of code several number of times. In general, statements are executed sequentially: The first statement in a function is executed first, followed by the second, and so on.
Programming languages provide various control structures that allow for more complicated execution paths.
A loop statement allows us to execute a statement or group of statements multiple times and following is the general from of a loop statement in most of the programming languages −
- The Infinite Loop
A loop becomes infinite loop if a condition never becomes false. The for loop is traditionally used for this purpose. Since none of the three expressions that form the ‘for’ loop are required, you can make an endless loop by leaving the conditional expression empty.
code:-
#include <iostream> using namespace std; int main () { for( ; ; ) { printf("This loop will run forever.\n"); } return 0; }
- ‘for (;;)’ construct to signify an infinite loop.
You can terminate an infinite loop by pressing Ctrl + C keys.
note:-it's just a sudo code if its not executing on your device make some changes in the further code this is only for understanding logic.
