    Array error learning from a book

    I placed the multi array below in my code straight from a book and get the following error:

    Number of initializers cannot be greater than the number of aggregate members

    Code:
    int multi[3][4] = {{1,2,3,4,5,6,7,8,9,10,11,12}};
    Does anyone see why this line would cause the error?

    Yes, and the error message says what is the problem: you are trying to initialise a two dimensional array with a two dimensional array whose inner array has more elements than that specified by the two dimensional array to be initialised.

    You probably want to write:
    Code:
    int multi[3][4] = {{1,2,3,4},{5,6,7,8},{9,10,11,12}};
    or if you are lazy:
    Code:
    int multi[3][4] = {1,2,3,4,5,6,7,8,9,10,11,12};
    However, I am usually confused by multi-dimensional arrays, so I try not to be lazy for my own sake.

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.
