Use strcpy() and then two strcat() calls.

And you're mixing C and C++ code.   If you want to use C, use printf(), not cout.
#include <string.h>

result[0] = '\0';
strcat(result, input);
strcat(result, "_");
strcat(result, inputType);

Hi keepworking,

For the record, it's "traditional" to use strcpy() to put the first string in the buffer and scrcat() to append additional strings.

Just for future knowledge, you could have done this with a single statement.  :)

  sprintf (result, "%s_%s", input, inputType);

Good Luck!
