For loop Structure in C and C++ For Loop : - In for loop first we give the initial value and then.it checks the condition if the condition is true then it enters the loop and execute all the statement inside the curly braces and after this it go to the third part that is increment/ decrement . And it again checks the conditions. In this way it runs till the condition is true. When the condition becomes false it come out of the loop. .   Syntax   for( Initialization ; Condition  ;  Increment/ decrement ) { body of the loop }   EX for(i=0;i<=10;i++) { /**************************/ } c programming language,c programming software,c programming download,c programming online,c programming examples,c programming tutorial,c programming code c programming w3schools,c++ compiler download,turbo c compiler,online c compiler,c compiler for windows,c++ compiler,online compiler online c++ compiler,gdb compiler,c pro...

  Control LOOP Loop are two type 1. Entry Control loop: - In which condition is checked at the entry point for the execution of the loop. For and while loop comes in this category 2.Exit control loop : - In which condition is checked at the last point for the execution of the loop. Do while loop is exit control loop. It execute at least once.         1. While Loop : - In while loop we first write the initial  value and                              then we checks the condition                             if the condition is true it enters the loop otherwise it comes out. In true condition it executes all the statement inside the curly braces. And then again checks. The condition this process repeats till the condition is true. Syntax Initialization; ...
