Abdulaziz, that is what called comparison

Answer 3

4 Thing I found wrong,
1. findLowest() function have different datatypes for its arguments in prototype and definition.
2.findLowest() function do not return anything.
3. Algorithm to calculate average is not defined.
4. Use == for comparison instead of just a single =.

Answer 7

calculate the average first, then assign it to average variable...then do the if else stmt

Answer 8

Resolved the error code.
Made few changes in FindLowest.
It would be more easier if you use for loop instead of if/else if in FindLowest function.
Hope help full...

that findlowest method is wrong
1.u dont return anything,it must return int
