re-enter the info.

I write the code to ask the user to enter some information like below:

Enter your name: Kewill
Enter your age: 20

After the user entered his/her name and age, he/she realise that he/she entered the wrong name.

My question is how to move the cursor back to "Enter your name: " and allow the user delete the wrong name and re-enter again.

you could use a combination of gotoxy(); and clrscr(); in <conio.h>
but this is compiler specific, check compiler help files for details.

Here's a real simple version of how to do this.
Hope it helps.

Code:

---

#include <stdio.h>
#include <stdlib.h>
#include <conio.h>

int main(void)
{
 char ans='\0';
 char name[BUFSIZ];
 char age[BUFSIZ];
 char input[BUFSIZ];

 do
 {
  clrscr();
  puts("");
  // get the name
  printf(" Enter your name:");
  if(fgets(input,BUFSIZ,stdin)!=NULL)
  {
  sscanf(input, "%s", name);
  }

  // get the age
  printf(" Enter your age:");
  if(fgets(input,BUFSIZ,stdin)!=NULL)
  {
  sscanf(input, "%s", age);
  }

  printf("\n name is %s", name);
  printf("\n age is %s\n", age);
  printf("\n type y if this is correct,  n if wrong <>");

  if(fgets(input,BUFSIZ,stdin)!=NULL)
  {
  sscanf(input, "%c", &ans);
  }
 } while(ans!='y');

 return EXIT_SUCCESS;
} // end int main(void)
