Loop Control Statement - " for Loop " 1

Loop Control :
Sometime we need to do a specific task more than one time.In that case,we don't write that statement again and again.We use loop controlling statement.

In " C " there are three loop controlling statement :
                                               
                                                  1. for
                                               
                                                  2.while
                                               
                                                  3.do.....while

for loop :
To use one or more statement for a selected time in " C " we use " for " loop.

Ex :
I need to print " SHUVO " for 50 times on computer screen.Here,no need to write "printf" for 50 times.We can do it more easily by using " for " loop.

                                                   for(i=1; i<50; i++)
                                                   printf("SHUVO");

The structure of "for loop" is as follow:
                     
                          for(initialization;                    condition;               increment/decrements)
                                     |                                                               |                                         |               |
          Variable and Assignment Operator             <, >, >=, <=, <<, ||                          ++           - -


Initialization :
The starting value of a loop is declared here.Usually,variables and assignment operators( = ) are used here.

Condition :
Here usually used relational expressions.When loop will end,that depends on this conditional section.If the condition become false in this section the program will also be terminated.

Increment :
Declared value of variables in the initialization section turned  incremented or decremented in this section.

Watch The Program :
                                                       #include<stdio.h>
                                                       #include<conio.h>
                                                       main()
                                                       {
                                                        int i=1;
                                                        for(i=1; i<=15; i++)
                                                        Printf("The Value is ?%d",i);
                                                        getch();
                                                        }

OUTPUT:

1,2,3,4,5,6,7,8,9,10,11,12,1315


Program Analysis:
->  for ( i=1; .....; ..... )
This is initialization part in for loop.Here the value of i is declared 1.

-> This is the conditional part.If the condition become satisfied printf() function will execute.So when i=1 and 1 is less than 15,condition is true.

-> for ( .......; .......; i++ )  
After executing printf(), i++ will execute.The loop will be working and value of i will be increasing by one every time until the condition become false.
