Answer:
for (i = 0; i < 100; i++)
Step-by-step explanation:
Required:
Which will iterate 100 times.
Analysing the loops one after the other

This loop begins at 0; i.e i = 0
and ends at 98; i.e. i<99
From 0 to 98 is 99; i.e. 98 - 0 + 1 = 99
Hence, this loop will iterate in 99 times

This loop begins at 1; i.e i = 1
and ends at 98; i.e. i<98
From 1 to 98 is 98; i.e. 98 - 1 + 1 = 98
Hence, this loop will iterate in 98 times

This loop begins at 0; i.e i = 0
and ends at 99; i.e. i<100
From 0 to 99 is 100; i.e. 99 - 0 + 1 = 100
Hence, this loop will iterate in 100 times

This loop begins at 1; i.e i = 1
and ends at 99; i.e. i<100
From 1 to 99 is 99; i.e. 99 - 1 + 1 = 99
Hence, this loop will iterate in 99 times
