for loop use is one are more then printing in printup 
statements.

for loop use is more then one calculation or process can be 
performed, for example:
          for(int i=0;i<5;i++)
          { 
                printf("%d",i);
           }
In the above example the printf statement can be excuted in 
five times.
 Output:0 1 2 3 4

for loop is used to repeate the process for certain number 
of time s known.

for loop is executed as long as condition is true and 
process the loop until condition is fail.

it is a loop which can have 3 conditions like
1)initiating a value to a variable
2)incrementation/decrementation
3)and a specific condition

for the repeated eecution of a statement or a block we use 
for loop.

testing the condition more than one time.when it gets true 
the loop will be finished.
