Difference between ‘In case’ and ‘ If’
There is a clear-cut difference in the usage of IN CASE and IF. In the case of ‘In case”, something is being done in anticipation of something else. Similarly we did ( or not) something anticipating something else. But in the case of ‘IF’ , nothing is being done anticipating something else. We do something only if a need arises. When ‘In case ‘ is used in the past , it explains why we did something in the past.
