Visual C++ - Simple Student Grading Logic

---

I have given here a simple student grading by using if conditions and pointer assignment.

Source Code

---

#include <stdio.h>

#include <iostream>

int main()

{

int i, arrMark[10];

char *grade = 0;

for(i = 0; i < 10; i++)

{

std::cout << "Enter %d Student Mark: " << i + 1;

std::cin >> arrMark[i];

}

printf("\n\nNo\tMark\tGrade\n");

for(i = 0; i < 10; i++)

{

if(arrMark[i] > 100)

grade = "Error";

else if(arrMark[i] > 90)

grade = "A+";

else if(arrMark[i] > 70)

grade = "B+";

else if(arrMark[i] > 50)

grade = "C+";

else if(arrMark[i] > 30)

grade = "C";

else

grade = "F";

printf("%d\t%d\t%s\n", i + 1, arrMark[i], grade);

}

return 0;

}

Output
