Write a program to read a 2D array marks which stores the marks of five students in three subjects. Write a program to display the highest marks in each subject

#include <stdio.h>
#include <conio.h>
int main()
{
int marks[5][3], i, j, max_marks;
for(i=0; i<5; i++)
{
printf("\n Enter the marks obtained by student %d",i+1);
for(j=0; j<3; j++)
{
printf("\n marks[%d][%d] = ", i, j);
scanf("%d", &marks[i][j]);
}
}
for(j=0; j<3; j++)
{
max_marks = –999;
for(i=0; i<5; i++)
{
if(marks[i][j]>max_marks)
max_marks = marks[i][j];
}
printf("\n The highest marks obtained in the subject %d = %d", j+1, max_marks);
}
getch();
return 0;
