Small Example of C language array pointer

1. function: enter 5 course scores of 6 students and calculate the average score of each student and the average score of each course.
2. C language implementation code: (in fact, it is implemented using two-dimensional arrays. the reference and transfer of two-dimensional arrays are completed using array pointers) Copy codeThe Code is as follows: # include <stdio. h>
# Define STUDENT 5
# Define SCORE 6
Void input_array (float (* score) [STUDENT]);
Void avg_score (float (* score) [STUDENT]);
Void avg_course (float (* score) [STUDENT]);
/**
* Calculate student average score and course average socore.
*/
Int main (){
Float a [SCORE] [STUDENT];
Input_array ();
Avg_course ();
Avg_score ();
}
Void input_array (float (* score) [STUDENT]) {
Int I, j;
For (I = 0; I <SCORE; I ++ ){
Printf ("input the % d student score:", I + 1 );
For (j = 0; j <STUDENT; j ++ ){
Scanf ("% f", score [I] + j );
}
}
}
Void avg_course (float (* score) [STUDENT]) {
Int I, j;
Float s;
For (j = 0; j <STUDENT; j ++ ){
Printf ("course % d", j );
}
Printf ("\ n ");
For (I = 0; I <SCORE; I ++ ){
S = 0;
For (j = 0; j <STUDENT; j ++ ){
Printf ("% f", * (score [I] + j ));
S + = * (score [I] + j );
}
Printf ("\ ts = % f, avg = % f \ n", s, s/STUDENT );
}
}
Void avg_score (float (* score) [STUDENT]) {
Int I, j;
Float s;
For (I = 0; I <STUDENT; I ++ ){
S = 0;
For (j = 0; j <SCORE; j ++ ){
S + = * (score [j] + I );
}
Printf ("% f", s/SCORE );
}
}
