For example, this would be an error: ```c 5 = 6 ``` #### Possible solutions: * check your assignment statement and provide a variable which will store the value. ```c int x = 5 ``` * if right-hand side of the assignment returns multiple values, left-hand side should have the same number of variables, delimited by commas: ```c float x, y, z x, y, z = Char.GetCoordinates(10@) // store X-, Y-, and Z- coordinates in three variables ``` --- # Agent Instructions This documentation is published with GitBook.
