    the display total the number of grade in 2 dimensional array
    i stuck in the middle don't know how to calculate the gpa realy stuck in thia part
    this is my program
    Code:
    #include<stdio.h>
    #include<stdlib.h>
    #define column_size 30
    #define row_size 50
    
    void input_table(int *rows,int *column,int arr[][column_size]);
    void output_table(int rows,int columns,const int arr[][column_size]);
    
    int main()
    {
    
    	int test_score[row_size][column_size];
    	int rows,columns,score;
    	
    	input_table(&rows,&columns,test_score);
    	output_table(rows,columns,test_score);
    
    	return 0;
    }
    void input_table(int *no_of_rows,int *no_of_columns,int arr[][column_size])
    {
    	int i,j;
                    printf("\n");
    	printf("\t\t\UNIVERSITY OF SUNDERLAND\n");
    	printf("\t\t\t------------------------\n");
    	printf("\n");
      	printf("Enter number of rows    : ");
    	scanf("%d",&(*no_of_rows));
    	printf("Enter number of columns : ");
    	scanf("%d",&(*no_of_columns));
    
    	for(i=1;i<=*no_of_rows;i++)
    		for(j=1;j<=*no_of_columns;j++)
    		{
    			printf("Enter value of test score [%d][%d] :",i,j);
    	     	scanf("%d",&arr[i][j]);
    		
    		}
    }
    void output_table(int rows,int columns,const int arr[][column_size])
    {    
    	int i,j;
    	
                    system("cls");
    	printf("\n");
    	printf("\t\t\tEXAMINATION PERFORMANCE REPORT\n");
    	printf("\t\t\t------------------------------\n");
    	printf("\n");
                    printf("Student No\tAACS1089\tAACS1283\tGrade Point Average\n");
    	printf("-------------\t--------\t--------\t-------------------\n");
    
    	for(i=1;i<=rows;i++){
    		printf("\t\n%3d",i);
    	for(j=1;j<=columns;j++)
    		printf("\t\t%3d",arr[i][j]);
    	}
    	
    	printf("\n\n");
    	printf("AVERAGE GPA = %d\n ");
    	printf("\n");
    	printf("HIGHEST GPA =  %d     obtained by student No.=\n");
    	printf("LOWEST  GPA =  %d     obtained by student No.=\n");
       
    	}
