converting from char * to int on result from strtok

input is something like "word-2" How do I convert from char pointer to int ?

1. char *tmp_result = NULL;
2. char standard = "";
3. int version = 0;
5. tmp_result = strtok( argv[1], delims );
6. printf( "token standard is "%s"
   ", tmp_result );
7. standard = *tmp_result;
9. if( tmp_result != NULL ) {
10. tmp_result = strtok( NULL, delims );
11. printf( "token tmp_result is "%s"
    ", tmp_result ); <===== prints "2" as it should be
13. version = *tmp_result;
15. printf( "token as_version is "%d"
    ", as_version ); <===== prints "50" after assignment

}

A char pointer refers to the start memory address of a string. You can't directly transfer to an int.

However, it your trying to convert a string (ie "123.42") then you can use atoi for integers or atof for real numbers
