To write into the oil_tanks array in the first place, you can use
assignment statements in which the array name, a bracketed integer index,
and the member-variable name appear on the left side:
*-- Array's name | | *-- Array's index | | | | *-- Member-variable name | | | | | | *-- Value to be stored | | | | v v v v oil_tanks[counter].radius = 8;
To read data from the oil_tanks array, once the data
have been inserted, you simply write an expression containing the
array name, a bracketed integer index, and the member-variable name. The
following expression, for example, yields the radius of the
cylinder stored in the place indexed by the value of
counter:
oil_tanks[counter].radius
