 printf("Enter your obtained marks:\t");         //a message to the user regarding the program
 scanf("%d",&marks);              //input taken from user.
                    
  if(marks<=100){              //if starts from here with a condition
  if(marks>=80 && marks<=100) printf("A+\n");       //else ....if ladder starts from here.
