C Program Code to find the grade of a student

This program code determines the grade of a student based on the following grade sheet. We have used an if else if statement to carry out the process.

Percentage	Grade
>90	First Class with distinction
80-90	First Class
70-80	Second Class
60-70	Third Class
50-60	Passed
<50	Failed

	#include<stdio.h>
	int main()
	{
	int m1,m2,m3,total;
	float p;
	printf("Enter the 3 marks (out of 100): ");
	scanf("%d%d%d",&m1,&m2,&m3);
	total =m1+m2+m3;
	p=(float)total/300;
	p=p*100;
	printf("Your Percentage is %f\n",p);
	if(p>=90)
	{
	printf(" You have First Class with Distinction");
	}
	else if(90>p&&p>=80)
	{
	printf("You have First Class");
	}
	else if(80>p&&p>=70)
	{
	printf("You have Second Class");
	}
	else if(70>p&&p>=60)
	{
	printf("You have Third Class");
	}
	else if(60>p&&p>=50)
	{
	printf("You have Passed");
	}
	else
	{
	printf("You have Failed");
	}
	getch();
	return(0);
	}
