Repeat the Program for again Search Array Element

Question

Repeat the Program for again Search Array Element.

 #include <stdio.h>
#define MAX_SIZE 100  

  int main()
  {
    int arr[MAX_SIZE];
    int size, i, toSearch, found;
    char repeat;

    printf("Enter the size of an array\n");
    scanf("%d", &size);
    printf("Enter the array elements\n");
    for (i = 0; i < size; i++) 
    {
      scanf("%d", &arr[i]);
    }
do{
printf("\nEnter element to search: ");
scanf("%d", &toSearch);
found = 0; 

 for(i=0; i<size; i++)
  {
      if(arr[i] == toSearch)
      {
          found = 1;
          break;
     }
 }
 
  if(found == 1)
  {
      printf("\n%d is found at position %d", toSearch, i + 1);
  }
 else
  {
      printf("\n%d is not found in the array \n", toSearch);
  }
  printf("\n \n \nPress Y to again Search Any Element in Array\n \nPress Any other Key to Exit the Program\n\n");
scanf(" %c \t",&repeat);
}
while(repeat == 'y' || repeat == 'Y' );
return 0;

}

I want to repeat my program when user give the input of Y || y otherwise it'll exit the program. In this code i want to make an array then search the element after this show's the results and in last repeat the code from the search the element block.

I ran your code and everything seems to be working properly except for this line:

scanf(" %c \t",&repeat);

Remove the \t from the scanf and it should work properly. You don't want to scan for a tab character, just the 'Y' or 'y' character.

Also, your use of newlines is a bit unusual. Try putting newline characters at the end of your strings as opposed to the beginning.

Updated code:

#include <stdio.h>
#define MAX_SIZE 100  

int main() {
  int arr[MAX_SIZE];
  int size, i, toSearch, found;
  char repeat = ' ';

  printf("Enter the size of an array\n");
  scanf("%d", &size);
  printf("Enter the array elements\n");
  for (i = 0; i < size; i++) 
    scanf("%d", &arr[i]);
    
  do{
    printf("Enter element to search: \n");
    scanf("%d", &toSearch);
    found = 0; 

    for(i=0; i<size; i++) {
      if(arr[i] == toSearch) {
        found = 1;
        break;
      }
    }
    
    if(found == 1)
      printf("%d is found at position %d\n", toSearch, i + 1);
    else printf("%d is not found in the array\n", toSearch);
    
    printf("Press Y to again Search Any Element in Array\nPress Any other Key to Exit the Program\n");
    scanf(" %c",&repeat);
  }
  while(repeat == 'y' || repeat == 'Y' );
  return 0;
}
