Row major order in 2d array

WebIt's a completely arbitrary decision. In Fortran, for example, "people" prefer column-major order, whereas in C "they" prefer row-major order. In C the row-major order is forced due to reasons of syntax and the fact that dimensions are not always known in advanced. Fortran doesn't have that problem, so according to your line of argument, column ... WebN is the number of rows in an array. M is number of columns in array Ques 17 Explain column major order with an example. Answer: Column Major Order is a method of representing multidimensional array in sequential memory. In this method elements of an array are arranged sequentially column by column. Thus elements of the first column …

Now my observations are: If Row Major Order is taken, then we have 2 arrays of a[3][4] so each array has $12$ elements. If we take Column Major Order, then we have 4 arrays of a[2][3]; that is we have only $6$ elements per array. sharon stone beauty secrets https://amazeswedding.com
