I have been trying to solve and sum the each row in the problem for like trying to from last two days with no luck . kinda new to programming and please help me out with this….the real problem im facing is when im trying to sum after initializing the the array of 20 students with 5 subjects ,in the first case i got sum of garbage value many times now im ended up with garbage of a code below.

im trying to oragnize the code function wise too!

would be gratefull if someone helps!

the problem says to find sum of each students marks average , number of students who have scored
below 50 in their average, he scores obtained by every student.

i dont wanna use pointers since it kinda messes up readability.

 #include <stdio.h>
  int sumofmarks();
  int main(){
 int row,col;

   printf("Enter the total number of student = ");   `students as columns`
   scanf("%d",&col);
 
    printf("Total number of subjects = ");
    scanf("%d",&row);                                `put marks as rows`

    int marks[col][row];
    for (int i=0; i<row; i++) {
        for(int j = 0; j<col; j++){
            printf("Enter the marks obtained by %d student n in %d subject =  ",i+1,j+1);
            scanf("%d",&marks[i][j]);
        }

    }
    sumofmarks(marks,row,col);   `fuction call`

}

int sumofmarks(int marks[10][10],int r,int c){  `sum funtion defination`
    int sum = 0;
     for (int i=0; i < r; i++) {
         sum=0;
         for(int j = 0; j < c; j++){
              sum +=marks[i][j];
           }
         printf("nThe Sum of marks of student %d is %d in 5 subjects",i+1,sum );
   }

   return sum;
}
