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 =.

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... https://code.sololearn.com/c4RdNkkedmNv/?ref=app

that findlowest method is wrong 1.u dont return anything,it must return int 2.the average variable,it is undefined.u are not assigning it to any value, but yet u use it inside the if else stmt 3.inside the if else statement, use == or === for comparasion not =
