problem in C

[esi]

I am new to using C language and also to programing and would like some help on the following problem.

Write a function to take integer input from user: If user input 1 then the program prints ONE and if user input 2 then program print TWO. If user input is neither 1 nor 2 then program prints: DEFAULT VALUE.
The program should ask user whether he want to repeat the programe again. If student enters ‘y’ then program is repeated and if student enters ‘n’ then program is terminated.
Note:
Use while selection statement to decide the repetition of program and use switch multiple selection statement to print ONE or TWO or DEFAULT VALUE based on the user input.

im having problem in repeating the whole thing. can anyone help me in this case. the source cde ive writen is as follows:

#include<stdio.h>
int main()
{
int a;
char b;
char y;
char n;
char counter;
y=3;
printf("Enter Number \n");
scanf("%d",&a);
switch (a)
{
case 1:
printf("\n You Entered one \n");
break;

case 2:
printf("\n You Entered Two \n");
break;
default:
printf("default");
}
printf("do u want to repeat?\n");
scanf("%d",&counter);
while (counter=y)
{
printf("Enter Number \n");
scanf("%d",&a);
switch (a)
{
case 1:
printf("\n You Entered one \n");
break;

case 2:
printf("\n You Entered Two \n");
break;
default:
printf("default");
}
}
}

1. Moved from C# to C board
2. Code tags added
You might want to edit your post to make the code indented.

You want to englobe your whole switch statement with a while loop. So you'd do something like :

char continue ='y';

while(continue == 'y')
{
          //  Do your stuff

         printf("Do you want to continue ?");
         c = getchar();  // Or a combination of fgets and sscanf.
}

It's good that you showed us your attempt.

Here are some suggestions for improving your code:
1. Use meaningful variable names.
2. Understand the difference between == (a comparison operator) and = (the assignment operator).
3. Try to reduce repetition in codes that you develop.
4. Use proper indentation to make your code more readable.

This is what your code should look like after putting the above suggestions in use:

#include<stdio.h>
int main()
{
  int number;
  char answer='y';
  
  while (answer =='y' || answer == 'Y')
  {
    printf("Enter Number\n");
    scanf("%d",&number);
    
    switch (number)
    {
    case 1:
      printf("You Entered one\n");
      break;            
    case 2:
      printf("You Entered Two\n");
      break;
    default:
      printf("default\n");
    }
    
    printf("do u want to repeat?\n");
    scanf(" %c", &answer); /*The space before %c tells scanf to ignore
                             any white space (like the newline) left in the input*/
  }
}
