C.16. Examples Using the for Statement
The following examples show techniques for varying the control variable in a for
statement. In each case, we write the appropriate for
header. Note the change in the relational operator for loops that decrement the control variable to count downward.
a) Vary the control variable from 1
to 100
in increments of 1
.
for ( int i = 1; i <= 100; ++i )
b) Vary the control variable from 100
to 1
in decrements of 1
.
for ( int i = 100; i >= 1; --i )
c) Vary the control variable from 7
to 77
in increments of 7
.
for ( int i = 7; i <= 77; i += 7 )
d) Vary the control variable from 20
to 2
in decrements of 2
.
