for Loop
A for loop is a repetition control structure that allows you to efficiently write a loop that
needs to execute a specific number of times.
Syntax
The syntax of a for loop in C programming language is:
for ( init; condition; increment )
{
statement(s);
}
Here is the flow of control in a ‘for’ loop:
1. The init step is executed first, and only once. This step allows you to
declare and initialize any loop control variables. You are not required to put a statement here, as
long as a semicolon appears.
2. Next, the condition is evaluated. If it is true, the body of the loop is
executed. If it is false, the body of the loop does not execute and the flow of control jumps to the
next statement just after the ‘for’ loop.
3. After the body of the ‘for’ loop executes, the flow of control jumps back up
to the increment statement. This statement allows you to update any loop control variables. This
statement can be left blank, as long as a semicolon appears after the condition.
