c program for matrix multiplication using pointers
How do you write a multiplication matrix program?
Initialise the value of the element (i, j) of the new matrix to 0.
Set an inner loop inside the above loop from k=0 to k=p.
Using the add and assign operator (+=) store the value of a[i][k] * b[k][j] in the third matrix, c[i][j].
Print the third matrix.Matrix multiplication Condition
To perform multiplication of two matrices, we should make sure that the number of columns in the 1st matrix is equal to the rows in the 2nd matrix.
Therefore, the resulting matrix product will have a number of rows of the 1st matrix and a number of columns of the 2nd matrix.
How to use pointer in matrix in C?
So easy, if you have a matrix: int m[2][2]={{1,0},{0,1}}; and you want to define a pointer to m, so you must declare: int (*mptr)[2][2]; mprt=m; // or mptr=&m; is the same.
How to do multiplication of pointers in C?
Multiplying pointers is not a valid operation in C because pointers do not represent numerical values in the same way that integers or floating-point numbers do.
Pointers are used to store memory addresses, which are the locations of data in a computer's memory.
