It would help if you give us more details. And I think you dont need a calculator tutorial, just c tutorials.
+, -, *, /
First you can start like this:
Define a variable; if the variable is
0, you perform an +
1, you perform a -
2, *
3, /

Code:

int a,v1, v2;
int result;
while(1){
  printf("Enter: 0 for addition, 1 for substraction, 2 for multiply, 3 for divide, 4 to quit!/n");
  scanf("%d", &a);
  if( a == 4 ) break;
  printf("Enter first value:");
  scanf("%d", &v1);
  printf("Enter second value:");
  scanf("%d", &v2);
  switch( a ){
    case 0:
      result = v1 +v2;
      break;
    case 1:
      result = v1 - v2;
      break;
    case 2:
      result = v1 *v2;
      break;
    case 3:
      result = v1 /v2;
      break;
  default:
      printf("Illegal operator/n");
      break;
  }
  printf("result = %d", result);
}
