Let’s understand the concept of exit criteria with an example—creating a loop to print
numbers from 1 to 100.
The exit criterion in this case is that the loop must stop when the 100th number is printed.
If the exit condition is not defined properly, the program may enter an infinite loop.
JUMP STATEMENTS
While executing a program, there are
times when we need to change the While (Loop-Condition)
flow of execution. This means altering {
the normal sequence of statements Statement 1;
to jump from one part of the program Statement 2;
...........
to another. For this we can use break Break; Execution of the program
and continue statements. ........... skips after the break
} statement is encountered in
Break Statement the loop body.
Statement
The break statement alters or change
the normal flow of execution of the
statement by terminating the existing loop and continues the execution of the statement
following that loop.
Break statement is used to come out of a loop early when the specific condition is met.
In break, the control skips the lines after the break statement is found and executes the first
statement outside the loop.
Critical Thinking
Example 1: Program to print number from 7 to 4, and another print
statement when you encounter break.
Pseudocode:
Program Start
set value of a to 7
while the value of a is greater that 0
display 'Current variable is: ' value of a
if value of a is equal to 4
break
decrease the value of a by 1
display Bye!
Program End
