Answer
Counters are numeric variables that are used to keep a record of the number of times a process is repeated. A counter is initialised with a numeric value. and it increases by 1 as the process starts repeating.
For example, suppose we want to print our name five times on the screen, then we use counter.
Program:
CLS
C=1
LET N$ = "TOM"
START:
PRINT N$
C = C + 1
IF C <=5 THEN GOTO START:
END
Output:
TOM
TOM
TOM
TOM
TOM
Here C is the counter variable and keeps on incrementing till it reaches 5.
