Thread: else if statement with example

I want to write c program to display status of student. if student get less then 40 marks then print " Failed". if he get mark's 40-50 then print "average. if he get marks 50- 70 then print "good" if he get mark's 70-100 then print "excellent "

I was trying to write program but I am not getting status of student. How to print different status of students ?

Code:

#include<stdio.h>
    
int main(void)
{
 int marks;
 
 printf(" exam marks : ");
 
 scanf("%d", &marks);
 
 
 if (0 < marks && marks > 40)
 {
  printf ("failed");
 }
 
 else if (40 < marks && marks > 50)
 {
       printf ("average");
 }
    
 else if (50 < marks  && marks > 70)
 {
       printf ("Good");
 }
 return 0;
   
 }
