Write a program to print the grades to a student.

 //program to print the grades to a student.

//marks < 35 is C

//35 <= marks < 70 is B

//70 <= marks < 90 is A

//90 <= marks <=100 is A+


#include<stdio.h>

#include<math.h>


int main()


{

int marks;

printf("enter marks(0-100)\n");

scanf("%d", &marks);

if(marks <35 ){

printf("grade C\n");

}

else if(marks >= 35 && marks < 70){

printf("grade B\n");

}

else if(marks >=70 && marks < 90){

printf("grade A\n");

}

else if(marks >=90 && marks <= 100){

printf("grade A+\n");

}

else{

printf("invalid marks");

}

return 0;

}

Output :

enter marks(0-100)
