Newbie need help

i need to produce a program which display Odd and Even number. User must be able to enter how many time the program loop.

example:
Enter loop: 2

Enter Selection: o
Enter Input 1: 1
Enter Input 2: 10

output:

number: 1 3 5 7 9
total: 25

Enter Selection: e
Enter Input 1: 1
Enter Input 2: 11

output:

number: 2 4 6 8 10
total: 30

Code:

int main()
{
      int i, total=0, input1, input2, counter;
      char selection;

      printf("Enter loop: ");
      scanf("%d", &counter);

      for(i=0; i<counter; i++)
      {
          printf("\nEnter selection: ");
          scanf("%s", &selection);
          printf("\nEnter input 1: ");
          scanf("%d", &input1);
          printf("\nEnter input 2: ");
          scanf("%d", &input2);

          switch (selection)
          {
              case 'e':
                       if(input1 % 2 == 0)
                       {
                           printf("\nEven Number: ");
                           while(input1<=input2)
                           {
                              printf("%d ",input1 );
                              total = total + input1;
                               input1+=2;
                           }
                           printf("\nTotal: %d", total);
                           printf("\n");
                       }
                       else
                       {
                           input1++;
                           printf("\nEven Number: ");
                           while(input1<=input2)
                           {
                                printf("%d ",input1 );
                                total = total + input1;
                                input1+=2;
                           }
                           printf("\nTotal: %d", total);
                           printf("\n");
                       }

                       break;

              case 'o':
                       if(input1 % 2 != 0)
                       {
                           printf("\nOdd Number: ");
                           while(input1<=input2)
                           {
                               printf("%d ",input1 );
                               total = total + input1;
                               input1+=2;
                           }
                           printf("\nTotal: %d", total);
                           printf("\n");
                       }
                       else
                       {
                           input1++;
                           printf("\nEven Number: ");
                           while(input1<=input2)
                           {
                               printf("%d ",input1 );
                               total = total + input1;
                               input1+=2;
                           }
                           printf("\nTotal: %d", total);
                           printf("\n");
                       }
                       break;

          }
       }

      system("pause");
      return 0;
}

my program always terminte after it runs once. where do i make the mistake ?

Thank You

this is wrong

Code:

scanf("%s", &selection);

use this instead

Code:

getchar(); /* kludge */
selection = getchar();

becouse selection is single char. Read this. When you use switch always use also default.

got it. thank you for helping
