CodePudding user response:

The problem here:
Score [STUD] [running]

So
for(j=0; j{
Sum [I]=sum pScore [I] + [I * n + j];
}
Is wrong
Sum [I]=sum pScore [I] + [I * COURSE + j];

Such ability can
The following Print function is the same problem

Column a pointer is an array of the number of columns for each of the mobile, the original array line corresponding row pointer course is several times? The memory of those empty array is empty
The book says column pointer is equivalent to the two dimensional array as a one-dimensional array
According to this problem is a string of number in discontinuous luo

Int a [2] [3]={6};
A [0]=={1, 2, 3} [0] a [0]==1 a [0] [1]==2 a [0] [2]==3
A [1]=={4 and 6} [1] a [0]==4 a [1] [1]==5 a [1] [2]==6

Two-dimensional array like excel spreadsheet, with two rows and columns to determine the specific position,

Int score [STUD] [running]; This is the original definition
Memory structure is STUD on the length of one by one, the COURSE of a one-dimensional array of storage, can be used as a one-dimensional array to no problem
Score [I] [j] in distance score the first address of memory is the I * COURSE
So when using one dimensional array, are to be calculated according to the position
