I am very new to this coding work and thus am facing issues with this code.

You should improve your knowledge about loops with visiting some Learn C tutorial to better understand what a loop in C mean. Most obvious are for loops when you can count up or down, or while loops, when you have some controlling condition in your code. See the tutorial for details.

There is not even the attempt of 'looping' in your code.
A simple loop I can imagine:

C

#include<stdio.h>
int main()
{
  char c;
  do
  {
    printf("enter your marks \n");
    int m=0;
    if (  scanf("%d",&m) == 1)
    {
      if (m>90)
      {
        printf("congratulations you got GRADE A");
      }
      else if (m>80)
      {
        printf("you got B GRADE");
      }
      else if (m>75)
      {
        printf("YOU got C grade");
      }
      else if (m>70)
      {
        printf("you got D grade");
      }
      else
      {
        printf("you got E grade");
      }
      printf("\n");
    }
    printf("do you wish to continue?\n");
    scanf(" %c", &c);
  } while (c == 'y');

  return 0;
}

First you need to add %d% in scanf to get numbers and second add printf("Enter Your Marks:") inside do-while loop to prompt marks for second time and third add || operator because user can enter 'Y' or 'y' for new marks.

#include<stdio.h>
main()
{
    char option;
	int m=0;
	do
	{
	    printf("Enter Your Marks: ");
	    scanf("%d",&m);
	    if (m>90)
    	{  
    	   printf("Congratulations you got GRADE A");	  
    	}	
    	else	
    	{
    		 if(m>80)
    		 {
    		    printf("You got B GRADE");	    
    		 } 	
    		 else if(m>75)
    		 {
    			printf("You got C grade");
    		 }	
    	     else if(m>70)
    	     {
    	    	printf("You got D grade");
    		 }	
    		 else
    		 {
    			printf("You got E grade");
    		 }				
    	}
        
    	printf("\nDo You Want to Continue? (Y/y): ");
        scanf(" %c", &option);
  } while (option == 'Y' || option == 'y');
	
	
	
}
