that such friends I am creating a program in c ++ with structures: 2. Store the names and ages of 10 people in an arrangement. Find the name corresponding to a certain age and the age corresponding to a person. Both options must be accessible through a menu: a) Search by name. b) Search by age. c) Exit.

but at the time of making the query by name it tells me that the person of that name does not exist in the registry I leave the complete code I would appreciate prompt help

Convert OutPutStreamWriter to ByteArrayOutPutStream Generate permutations from a number in PHP

When comparing strings, as is your case when comparing names, it is not good to use == , it is better to use a string comparer. I suggest changing the line if (persona[1].nomb == persona[i].nombre) to the following: int strcmp ( const char * str1, const char * str2 ) . This condition will return a 0 when the two strings are equal.

Here is an example of how that command works:

char key[] = "apple";
  char buffer[80];
  do {
     printf ("Guess my favorite fruit? ");
     fflush (stdout);
     scanf ("%79s",buffer);
  } while (strcmp (key,buffer) != 0);
  cout<<"Correct!!"<<endl;

I say it's not good to use == because == will not always work, only in cases where the string overloads the operator. In the case where you do not overload the operator, when using == you will be comparing the memory address instead of the object itself. For this reason I prefer to use strcmp .
