Write the function READ_NB_ROWS which reads the number of rows R of a matrix.

Write the function READ_NB_COLUMNS which reads the number of columns C of a matrix.

Write the function READ_MATRIX taking 3 parameters MAT, R, and C which reads the components of a matrix MAT of the type int and dimensions R and C.
