What is Loop
Loop is used to reuse any code again and again there are three types of loop in C
For loop
While loop
Do while loop
For loop
While loop
Do while loop
For loop
For initialize the value a=2
check the condition a<=10
and inc/dec the value a++/a--
Syntax:-
For(initialization;condition;inc/dec)
{
statement
}
check the condition a<=10
and inc/dec the value a++/a--
Syntax:-
For(initialization;condition;inc/dec)
{
statement
}
