    Question getch() doesn't wait for input

    I am working on Dev-C++. But the output window closes as soon as the program gets executed. I read through their forums and I tried using getch() but it isn't of any use.

    conn.c

    Code:
    #include <stdio.h>
    #include <windows.h>
    #include <conio.h>
    #include <stdlib.h>
    #include "C:/Program Files/MySQL/MySQLServer5.1/include/mysql.h"
    
    int main(int argc, char **argv)
    {
    
      MYSQL *conn;
      conn = mysql_init(NULL);
    
      if (conn == NULL) {
          printf("Error %u: %s\n", mysql_errno(conn), mysql_error(conn));
          exit(1);
      }
    
      if (mysql_real_connect (
                conn,           /* pointer to connection handler */
                "localhost",    /* host to connect to */
                "root",          /* user name */
                " ",              /* password */
                "test_db",     /* database to use */
                0,               /* port (default 3306) */
                NULL,           /* socket or /var/lib/mysql.sock */
                0 ) == NULL) {
          printf("Error %u: %s\n", mysql_errno(conn), mysql_error(conn));
          exit(1);
      }
    
      if (mysql_query(conn, "create database test_db")) {
          printf("Error %u: %s\n", mysql_errno(conn), mysql_error(conn));
          exit(1);
      }
    
    
      mysql_close(conn);
      printf("Database successfully created.");
      getchar();
      return (0);
    
    }
    any thoughts on why this happens?

    You also have exit calls in there that aren't waiting for keypresses either, so it's possible one of your if checks is just failing.

    Hope is the first step on the road to disappointment.

    Yes, there are chances and i have already tried commenting all the exit calls. Rather, I made the program very simple.

    Code:
    #include <stdio.h>
    #include <windows.h>
    #include <conio.h>
    #include "C:/Program Files/MySQL/MySQLServer5.1/include/mysql.h"
    
    
    int main(int argc, char *argv[])
    {
        MYSQL *conn;    /* pointer to connection handler */
        conn = mysql_init ( NULL );
        mysql_real_connect (
                conn,           /* pointer to connection handler */
                "localhost",    /* host to connect to */
                "root",    /* user name */
                " ",     /* password */
                "client_test_db",         /* database to use */
                0,              /* port (default 3306) */
                NULL,           /* socket or /var/lib/mysql.sock */
                0 );            /* flags (none) */
        printf("hello");
        mysql_close ( conn );
    	getch();
        return 0;   
    
    }
    But still it isn't working!! I mean the dev-c++ doesn't retain the output window.

    And in between, thanks for replying.
